Zájem současné sociologie a dalších společenských věd o výzkumy spokojenosti a štěstí zatemňuje skutečnost, že původně právě sociologie chtěla „štěstí" poskytovat a nahrazovat tak náboženské přístupy ke světu. Tento implicitně nábo- ženský charakter je patrný i v rané české sociologii v dílech prvních propagátorů sociologie, jako byl především Emanuel Makovička, a později u některých následovníků a epigonů T. G. Masaryka, v meziválečném období zejména u Ladislava Kunteho, R. I. Malého, Alexandra Sommera-Batěka, Jindřicha Fleischnera a Jana Duška. Z hlediska vývoje české (...) sociologie šlo o zcela okrajové postavy, ačkoli mnohé z nich vynikly v jiných oblastech, jako celek jsou nicméně vyjádřením jednoho z aspektů dobových teoretických úvah o společnosti, jejím uspořádání a vývoji, na který by nemělo být zapomínáno. Zatímco T. G. Masaryka a pozdější akademické sociology „omezoval" vědecký charakter jejich práce, a i pokud směřovali k sociálnímu reformismu, oddělovali jej od teoretické sociologie, „sociologie vedoucí ke štěstí" nalezla plné uplatnění ve vizích a ambiciózních projek- tech těchto amatérských takésociologů - třebaže skončily faktickými nezdary nebo ani nedošly praktického naplnění, ostatně stejně jako v případě jejich pravzoru, Comtova pozitivistického apoštolátu.

Obiettivo di questo articolo sarà presentare l’analisi fenomenologica e teoretica che Sartre propone del concetto di malafede, a partire dal romanzo La Nausea fino all’opera L’essere e il nulla. Ricostruendo il procedimento sartriano, che dall’atteggiamento interrogativo dell’uomo di fronte all’essere porta alla posizione del non-essere, giungeremo alla libertà e all’angoscia, quali caratteri costitutivi dell’essenza umana. Il tentativo di fuggire dalla libertà, a cui per Sartre siamo condannati, e dall’angoscia che da essa deriva, condurrà l’uomo sartriano all’autoinganno, ad una vita inautentica… (...) alla malafede.

Tato studie je recenzní statí ke knize Andrew MCGETTIGAN, The Great University Gamble: Money, Markets and the Future of Higher Education. London: Pluto Press, 2013. Klíčovým motivem studie je využití McGettiganovy analýzy technických aspektů reformy univerzitního systému započaté v Anglii na konci první dekády jednadvacátého století pro výklad vzestupu specifického režimu vzdělávání vyjádřeného v jazyce a logice „trhu a peněz". Vzestup tohoto režimu je interpretován s ohledem na procesy odpojování univerzitního prostředí od dosavadního vzdělávacího rámce spojeného s veřejnými zájmy. Studium (...) způsobů, jakými procházejí peníze zaváděným systémem vzdělávání, odkrývá novou podobu konfrontace klasických ideálů univerzitní výchovy s realitou masového vzdělávání. (shrink)

The present essay provides an overview of the images of seventeenth-century philosophy in the Rivista di storia della filosofia (then retitled Rivista critica di storia della filosofia) in the years 1946–1983. Founded in 1946 by Mario Dal Pra, the journal promoted a new anti-idealistic approach to the history of philosophy. Based on philological accuracy, this approach enhanced the complexity of history and the interdependence of different fields of knowledge. In particular, the unprecedented emphasis on the connections between science and philosophy (...) entailed a preeminent place for empiricism in the Rivista. This explains why this essay focuses on empiricist currents in seventeenth-century philosophy and especially on three of their representatives, namely Galileo Galilei, Thomas Hobbes and Francis Bacon.

Debata o tzv. „Novém Humovi“ byla v posledních desetiletích dominantním tématem humovské interpretace. James Hill ve svém příspěvku v tomto časopise podporuje hlavní požadavek „novohumovců“, který vymezuje Huma jako epistemologického skeptika a ontologického realistu. Vůči tomuto pojetí máme několik výhrad. Některé se týkají nejasností v definici realismu a celkově i smysluplnosti projektu „Nový Hume“. Některé se týkají konkrétních Hillových argumentů zaměřených na Humovy Dialogy a především jeho tvrzení, že v tomto díle lze nalézt další důkaz Humova realismu.

Larry Laudan v článku z roku 1983 označil problém demarkace, tj. rozlišení „vědy" a „pseudovědy", za filosofický pseudoproblém, kterým není třeba se zabývat, a slova „vědecké" a „pseudovědecké" za prázdné pojmy, které můžeme z našeho slovníku zcela vyškrtnout. V předkládané studii zpochybňuji toto Laudanovo stanovisko a předkládám argumenty ve prospěch tvrzení, že 1) rozlišení vědy a pseudovědy představuje důležitý a aktuální problém, kterým je třeba se zabývat, a že 2) možný způsob řešení tohoto problému nabízejí současná sociální studia vědy. Jejich (...) východiskem je pojetí vědy jako „formy života" a pojetí demarkačního kritéria jako proměnlivého souboru charakteristik, který sice nelze jednoznačně definovat, ale přesto jej lze zkoumat, a to prostřednictvím sociologické analýzy vědecké praxe. Mým záměrem je na příkladu několika vzorových studií představit specifika sociologického přístupu z hlediska jeho metodologie i povahy nabízených řešení a zhodnotit jeho možnosti i omezení pro filosofii vědy.

Článek se zabývá problematickou politické korektnosti ve vztahu k feministické filosofii vědy. Zaměřuje pozornost na užší pojem politické korektnosti - hodnotově motivovanou nekorektní práci s fakty. Konstatuje, že navzdory explicitnímu soustředění feministických autorek a autorů na význam hodnot v projektu vědy nelze chápat feministickou filosofii vědy jako politicky korektní nebo jako vybízení k politicky korektní vědě. Naopak se politicky korektní argumentace v tomto užším smyslu mohou dopouštět i práce vystupující proti feministické či politicky korektní agendě ve vědě.

V rámci filosofie věd panuje široká shoda na tom, že druhá polovina 20. století složila „labutí píseň" pozitivismu. Milton Friedman a Paul Samuelson, dva klíčoví autoři k metodologii ekonomie v daném časovém období, přitom tento vývoj ve filosofii vědy prý nikdy nereflektovali. Pozitivistická východiska - v prvé řadě v podobě redukcioni- stického přístupu - jsou tudíž stále přítomna ve vlivných teoretických konceptech rozvinutých ekonomy hlavního proudu. Značný počet autorů však v současnosti sdílí náhled, že tyto koncepty v nezanedbatelné míře přispěly (...) k vývoji, jenž ústil ve finanční krizi, vrcholící v letech 2008 a 2009. Předkládaný článek se proto táže, zda to byla právě krize - v níž mnozí spatřují empirické zamítnutí řady pozitivistických konceptů - která napsala „labutí píseň" pozitivismu v ekonomii hlavního proudu.

Este trabalho desenvolve uma investigação sobre as noções de coerência e comunidade nas obras de Bento de Espinosa (1632-1677), em especial na Ética demonstrada em ordem geométrica. A noção de coerência, entendida como modo pelo qual as partes da natureza se relacionam para compor o todo do universo, é um problema central em toda a história da filosofia. Espinosa também se posicionou em relação a essa questão, formulando uma teoria que procura explicar a relação entre as partes do universo sem (...) recorrer a nenhuma causa exterior a ele, configurando assim uma filosofia da imanência. Nessa perspectiva, o objetivo da pesquisa consiste em mostrar como o problema da coerência apareceu em diferentes campos da obra espinosana, sendo sempre solucionado através de uma mesma explicação imanente da natureza, que se estabeleceu definitivamente com a introdução da noção de comum na cadeia dedutiva da Ética. Para isso, partimos de uma perspectiva histórica e examinamos inicialmente algumas cartas de Espinosa, verificando como a pergunta sobre a coerência da natureza foi ali respondida. Posteriormente, ao analisar a Ética, apresentamos como, em cada de uma de suas cinco partes, a ideia de comunidade se faz presente, emergindo tanto no campo especulativo quanto no campo prático.

Mimarlık diğer sanat dallarından iki bakımdan ayrılır. İlk olarak mimari yapıtlarla etkileşim kaçınılmazdır. Müzik dinlemeden, tiyatro veya sinemaya gitmeden, resim veya heykel sergilerini gezmeden yaşamımızı sürdürebiliriz ancak mimari yapılar olmadan bu olanaklı olmaz. Bu bakımdan mimarlık sanatlar içinde belki de insan yaşamını en fazla etkileyen daldır. İkinci olarak mimarlık bir yaşam gereksinimini karşılayan, böyle bir işlevi olan belki de tek sanat dalıdır. Örneğin resim, heykel, şiir, sinema veya tiyatro yapıtlarını sanatsal açıdan değerlendirirken hangi gereksinimimizi karşıladıkları sorusunu sormayız. Buna karşılık mimari (...) yapılar barınma başta olmak üzere bir dizi maddi gereksinimimizi karşılarlar.

Tato studie se zabývá dvěma spřízněnými jevy odehrávajícími se ve vědeckém prostředí. Jedná se o fenomén frustrace ve vědecké praxi a s ním spojenou touhu po rozpoznání vlastního výzkumu vědeckou komunitou a následně o otázku uznání od akademického společenství. Zmíněné fenomény jsou přitom úzce propojeny s ústředním tématem filosofie a sociologie vědy: kdo rozhoduje, co bude předmětem vědeckého bádání? Předkládaná studie nejprve představuje Mertonův mýtus o okamžitém rozpoznání vědeckého objevu a následně prostřednictvím exkurzu do oblasti ekonomie a na příkladech z (...) vědecké praxe poukazuje na jeho neplatnost.

Poppera a tvrdošíjného zastánce kritického racionalismu, neboť právě Agassi ve svých dílech rozebírá dopady vědeckého vyloučení a neochoty naslouchat. (shrink)

Tato studie se zabývá zobrazováním alchymie v malbách, knižních ilustracích i v architektuře v období raného novověku. Na jednotlivých příkladech obrazů či ilustrací prezentuje různé aspekty alchymistova života i jeho práce. Nezabývá se symbolickou alchymickou ikonografií, ale zaměří se především na zobrazování prostředí a vybavení alchymických dílen i osobností samotných alchymistů. Soustředí se zejména na vyobrazení zařízení alchymických laboratorií, s nimiž se lze setkat jak u renesančních malířů, tak v ilustracích alchymických rukopisů a poměrně ojediněle i v české architektuře. Poskytuje (...) také pohled na vyobrazení vzniklá v souvislosti s literární kritikou alchymie. Alchymisté byli zejména v dílech předních evropských humanistů často záměrně zesměšňováni, kritizováni a označováni za blázny a zloděje. V závěru se zabývá vybranými příklady ze žánrového umění, kde byli rovněž alchymisté zobrazováni často satiricky, ale i s určitou úctou, jako vzdělaní učenci. Výtvarné umění raného novověku nám představuje různé aspekty života alchymistů a je v dnešní době jednou z možností, jak se přiblížit porozumění jejich vědeckým aktivitám. Jak však studie ukazuje, k těmto obrazovým materiálům je třeba přistupovat kriticky. (shrink)

Dini epistemoloji, teistik inançların rasyonel zeminde gerekçelendirilme yollarını arayan, çağdaş epistemolojinin bir alt dalıdır.

Cílem článku je podat kritický rozbor predikcí týkajících se budoucnosti sociálních věd, jak je formuluje Ladislav Kvasz pod záštitou svého projektu „formální epistemologie". Modelem dynamiky vztahů mezi obory na vědeckém poli nabízí Kvasz v otázce střídání paradigmat alternativu ke Kuhnově teorii vědeckých revolucí. Text zkoumá, na jakých základech je mechanismus změn u Kvasze vystavěn a co z toho plyne pro relevanci předpovědí z tohoto modelu vyvozených - především těch o sociálních vědách. K tomu slouží souběžné představení historické metody Michela Foucaulta, (...) který zdůrazňuje potřebu vyvarovat se zavádění falešných kontinuit ve zkoumání trajektorií vědeckých oborů, u kterých dochází ke zlomům v jejich epistemické struktuře. Zvláštní zřetel je kladen na souvislost predikcí s možnostmi odlišit epistemologicky a sociologicky uchopitelné prvky spojené s chodem vědy. Jako klíčový moment se tedy ukáže možnost práce se sociálně vědními obory pomocí jemných nástrojů, které Kvasz vyvinul na vědách exaktních. (shrink)

Predication is a lingual relation. We have this relation when a term is said (λέγεται) of another term. This simple definition, however, is not Aristotle’s own definition. In fact, he does not define predication but attaches his almost in a new field used word κατηγορεῖσθαι to λέγεται. In a predication, something is said of another thing, or, more simply, we have ‘something of something’ (ἓν καθ᾿ ἑνὸς). (PsA. , A, 22, 83b17-18) Therefore, a relation in which two terms are posited (...) to each other in a way that one is said (predicated) of the other is a predication. The term of which the other term is said is called a subject (ὑποκειμένον) and the other, which is said about the subject, is called the predicate. Thus, in a predication the predicate is predicated of the subject; given that being predicated is almost as the same as being said. The relation between being said and being predicated is so close that ‘if something is said of a subject both its name and its definition are necessarily predicated of the subject.’ (Cat., 5, 2a19-26) This, however, is true only about the second genera and not the accidents. a) Nature of relation in predication What is Aristotle’s theory about the nature of the relation in a predication? How does he fundamentally understand this relation? Phil Corkum distinguishes between predication logic and traditional term logic and argues that the relation between subject and predicate in Aristotle is of the latter kind. While in predicate logic, subjects and predicates have distinct roles, they have the same role in traditional term logic. In predication logic, subjects refer, but predicates characterize. Thereupon, a sentence expresses a truth if the object to which the subject refers is correctly characterized by the predicate. In traditional term logic, both subjects and predicates refer and a sentences expresses a truth if both name one and the same thing. He concludes that Aristotle ‘problematically conflates prediction and identity claims’ because while he thinks both subjects and predicates refer, he would deny that a sentence is true just in case the subject and the predicate name one and the same thing. Based on this, Corkum believes that Aristotle’s core semantic is not identity but the weaker relation of constitution, which is a mereological interpretation: ‘All men are mortal’ is true just in case the mereological sum of humans is part of the mereological sum of mortals. b) Aristotle’s theory of predication: one or two theories? Frank Lewis finds an inconsistent gap between the theory of predication in the Categories and that in the later books of the Metaphysics VII, 6. So too Joan Kung, Terry Irwin, Daniel Graham. c) Distinction of ‘being said of’ and ‘being in’ Owen enumerates the texts in which Aristotle’s distinction between ‘being said of’ and ‘being in’ is asserted: OI. 11b38-12a17; To., 127b1-4; Cat. 1a20-b9; 2a11-14; 2a27-b6; 2b15-17; 3a7-32; 9b22-24 d) Predication in Aristotle and the standard ‘S is P’ Marie De Rijk Lambertus thinks that the ‘S is P’ pattern is misleading when it comes to express predication in Aristotle. In his view, ‘The Aristotelian procedure should be described in terms of appositively assigning an attribute (κατηγορούμενον) to a substrate (ὑποκείμενον), rather than ascribing a predicate to a subject by means of a copula…. The comment should be considered an attribute which is said to fall to a substrate, without understanding this procedure in terms of sentence predication.’ e) Aristotle’s predication: bipartite or tripartite? It is a difficulty to make Aristotle’s theories of name-verb predication and tripartite predication consistent. The reason is that tripartite is not consistant with his name-verb structure based on which he says that the predicate term is the ‘verb.’ (20a31; 20b1-2; 16a13-5) The problem is that in a tripartite form like ‘Socrates is white’ we cannot take ‘is white’ as the verb because, based on Aristotle himself, no part of a verb can be significant itself. (16b6-7) However, his assertions about the equivalences between the two structures (OI. 12, 21b9-10; PrA. 51b13-16; Met., 1017b22-30) must mean that they are not inconsistent in his own view. Thus, as Allen Bāck points, ‘Aristotle seems to think that he has a single, consistent theory.’ The sense of saying or speaking as the root sense of rhema makes the relation between predication (saying something of something) and verb more interesting. The use of rhema in the sense of a long expression approves this. In Plato’s work (399ac) where Socrates claims that the name anthropos derives from anthron ha opopen (‘he who examines what he has seen’) we have an onoma from, or in place of, a rhema. 1) Subject The subject (ὑποκειμένον) is that of which another term is said or predicated. Aristotle’s own definition is of a much more philosophical value: ‘By subject I mean that which is expressed by an affirmative term (λέγω δὲ ὑποκείμενον τὸ κάταφάσει δηλούμενον).’ (Met., K, 1067b18) Throughout Aristotle’s work, three kinds of subjects can be found: possible, prime and absolute subject. a) Possible subject Those things that can take the position of a subject in a predication we call possible subjects, no matter they can or cannot take the position of predicate in any predication. All terms except the ultimate predicates are possible subjects because they can take the position of subject. b) Prime subject Those that in any predication can only take the position of a subject and not the position of a predicate are prime subjects. (Cat., 5, 3a36-b2; Met., Z, 1028b36-1029a1) This is the truest sense of subject and belongs only to substances. (Met., Z, 1029a1-2) In fact, ‘that which is not predicated of a subject, but of which all else is predicated’ is a substance. (Met., Z, 1029a7-9) In Categories, besides primary substances (Cat., 2, 1b3-6), individual qualities are also said not to be able to be said of anything else. (Cat., 2, 1a23-29) Aristotle’s examples are a certain ‘knowledge-of-grammar’ (τὶς γράμματικὴ) and ‘an individual white’ (τὸ τὶ λευκὸν). Thus, although substances are indeed in the truest sense individuals and, thereby, in the truest sense primary subjects, other individuals can take the position of subject as well. c) Absolute subject While substances are prime subjects of all other things, there is still something of which substances can be predicated and this predication is not an accidental predication: matter. (Met., Z, 1029a21-24) This predication is, indeed, the predication of a ‘form or this’ on matter and material substance. (Met., Θ, 1049a34-36) The only thing that is absolutely a subject, therefore, and can be a predicate is prime matter (πρώτη ὓλη). (Met., Θ, 1049a24-27) d) Subject and substance The most important thing in being a substance is being a subject: ‘It is because the primary substances are subjects for all the other things and all the other things are predicated of them or are in them, that they are called substances most of all.’ (Cat., 5, 2b15-17) And what is nearer to this position is more a substance as a species is more a substance than a genus.’ (Cat., 5, 2b7-8) e) Primary versus accidental subject A subject is a primary subject in a predication when the predicate is predicated of it as itself. In such a case, the subject is the subject of the predicate qua itself and not qua something else. A subject, on the one hand, is an accidental subject when it is not the primary subject of the predicate that is predicated on it. It means that a subject is an accidental subject when the predicate is predicated of it not qua itself but qua something else. An accidental subject is, therefore, anything other than a substance. 2) Predicate as universal It is evident from our discussion of kinds of subjects that except matter, primary substances (if we ignore both accidental predication and cases of absolute subjects) and other individuals, everything else can take the position of a predicate. Since primary substances are individuals, it results that everything except matter and individuals are capable to take the position of predicate. The immediate consequence of this is that the predicate must be a universal. When individuals cannot take the position of predicate, this position cannot be taken by any particular. Therefore, only universals can be predicated of others. Moreover, albeit universals can be a simple subject (for another universal), they are not prime subjects. The closeness of universal and predicate is to the extent that Aristotle differentiates universal from subject. (Met., Θ, 1049a27-30) 3) Categories or classes of predicates Aristotle distinguishes ten highest classes into one of which each predicate must necessarily fall: substance (or what a thing is), quality, quantity, relation, place, time, position, state, activity and passivity. (Cat., 4, 1b25-27; To., I, 9, 103b20- ; PsA., A, 22, 83b13-23) The substance counted among predicates must refer to secondary and not primary substances not only because Aristotle insists that primary substances cannot be predicated but also from his own examples of the category of substance: man and animal. (To., I, 9, 103b25) However, if a predicate be asserted of itself or its genus be asserted of it, the predicate signifies substance or what is; but if ‘one kind of predicate is asserted of another kind,’ it signifies one of the other nines. (To., I, 9, 103b30) These categories are so comprehensive that no predicate can remain outside them so that even non-being has as many senses as categories. (Met., M, 1089a26-30) a) That whether Aristotle’s categories are merely linguistic or fundamentally ontological is a so much controversial dispute. Some like G. E. R. Lloyd believe that ‘categories are primarily intended as a classification of reality … rather than of the signifying terms themselves.’ b) Although Aristotle’s categories have been historically regarded as a classification of predications, there are some recent commentators like Jonathan Barnes that think it is classifying predicates and not predications. 4) Kinds of predicates In his introduction of Categories, as J. W. Thorp truly points out , Aristotle distinguishes between the category of substance and the other categories using μὲν ... δὲ construction. This construction illustrates that beside tenfold classification of categories, there is an even more crucial differentiation between two kinds of predicates: substance or what is on the one hand and the other nine ones on the other hand: the distinction between what is predicated of the subject as what it is and what is predicated of it as an accident. Therefore, we have three kinds of classification - a twofold, a fourfold and a tenfold-complicatedly classifying the same thing, viz. the predicate. Predicates can be divided also to four kinds: property, definition, genus and accident. (To., I, 4, 101b11-20) A property is that predicate that is convertible with its subject and does not signify its essence. A definition is that predicate that is convertible with its subject and signifies its essence. It is a genus if it is not predicated convertibly and is contained in the definition of its subject. And it is an accident if it is neither convertible nor contained in the definition of its subject. (To., I, 8, ^103b3) All of these four kinds are among categories. (To., I, 9, 103b20) It seems that there might be some kind of relation between the twofold and the fourfold distinction: whereas genus and definition are predicated as what it is, accidents are not so predicated. There seems to be some rules that determine to each of these four kinds each predicate belongs. At To., IV, 123b30ff. Aristotle asserts: ‘If B has a contrary and A does not, then B does not belong to A as its genus.’ There is a dispute around per se accidents (τὰ καθ’ αὑτὰ συμβεβηκότα) (Topics., 102a18) whether they must be regarded as either of the four kinds or as a fifth kind. Barnes (1970) argued that they ‘do not fit at all neatly into the fourfold classification.’ He argues that based on the definition of accidents at A, 5, 102b4-5, they must be accidents but based on another definition, A, 5, 102b6-7, they cannot be accidents. He also defends the view that they are not properties. Barnes concludes: ‘This shows that the two definitions are not equivalent, and hence that the ‘predicables’ are not well-defined.’ Demetris J. Hadgopoulos defends the view that the two definitions of accidents are equivalent and per se accidents are properties. 5) Five types of predications We have five kinds of predications based on our division of subjects and our discussion of predicates: simple, primary (itself divided to substantial and accident), accidental (itself divided to primary and secondary), aoincidental and absolute predication. a) Simple predication. This is a predication in which a universal is predicated of either a particular or a universal subject. This sense of predication includes all other senses except the first kind of accidental predication. b) Primary predication. This is a predication in which a universal is predicated of a primary subject, namely a substance. A primary predication is of two kinds: i) Substantial predication. A primary predication in which the predicate is part of, or is included in, the definition of the subject. The universal that is the predicate here is the definition or the genus or the species or the diferentia of the subject. It is this predication that Aristotle calls a unity: ‘A statement may be called a unity … because it exhibits a single predicate as inhering not accidentally in a single subject.’ (PsA., B, 10, 93b35-37) It is only substantial predicates that can be predicated of each other: ‘Predicates which are not substantial are not predicated of one another.’ (PsA., A, 22, 83b18-19) Aristotle defines a substantial predication also in another way. A predication in which a higher genus is predicated on a lower genus, species, a substance or an individual, (or a species is predicated on an individual) is a substantial predication. Therefore, a substantial predication is a predication in a series that has individuals on one of its ends and a general category on its other end. In fact, only substantial predicates can be predicated of one another. (PsA., A, 22, 83b17-19) This series cannot be an infinite series because otherwise not only substances would not be definable but also a genus would be equal to one of its own species. (PsA., A, 22, 83b7-10) -/- ii) Accident predication. A primary predication in which the predicate is not part of, or is not included in, the definition of its subject. The universal that is the predicate here is the property or the accident of the subject. c) Accidental predication. This is a predication in which the subject is not a primary subject and its predicate is a substance. This predication is of two kinds: i) Primary accidental predication. This is a predication in which an accident is predicated of substance. Such a predication can go ad infinitum, which is inferable from Aristotle’s assertion that the secondary accidental predication cannot go ad infinitum. ii) Secondary accidental predication. It is a predication in which an accident is predicated of another accident. Such a predication, Aristotle asserts, cannot go ad infinitum because even more than two accidents cannot be combined. Now what is the meaning of Aristotle’s assertion that we cannot continue this ad infinitum? Does it mean that we cannot continue the predication ‘The musician is white’ and say ‘The white is Athenian?’ But why not? Or maybe he means that by adding any predication, we are still in a condition of predicating two accidents of a substance on each other. -/- As primary subjects, substances can also take the position of predicate though not essentially but accidentally. In propositions like ‘the white is a log’ or ‘That big thing is a log’ we observe substance taking the position of predicate but this is only accidentally: ‘When I affirm ‘the white is a log,’ I mean that something which happens to be white is a log- not that white is the subject in which log inheres (οὐχ ὡς τὸ ὑποκείμενον τῷ ξύλῳ τὸ λευκόν ἐστι), for it was not qua white or qua a species of white that the white (thing) came to be a log (οὔτε λευκὸν ὄν οὔθ᾿ ὃπερ λευκόν τι ἐγἐνετο ξύλον), and the white (thing) is consequently not a log except incidentally.’ (PsA., 22, 83a3-9) Aristotle compares this accidental use of substance in the position of predicate with the substantial use of it in the place of a subject: ‘On the other hand, when I affirm ‘the log is white,’ I do not mean that something else, which happens to be a log, is white (οὐχ ὃτι ἓτερόν τί ἐστι λευκόν, ἐκείνῳ δὲ συμβέβηκε ξύλῳ εἶναι), (as I should if I said ‘the musician is white,’ which would mean ‘The man who happens also to be a musician is white’); on the contrary, log is here the subject- the subject which actually came to be white, and did so qua wood or qua a species of wood and qua nothing else.’ (PsA., 22, 83a8-14) Aristotle asks us not to call propositions like ‘The white is a log’ a predication at all or at least call them accidental predication instead of simple (ἁπλως) predication. (PsA., A, 22, 83a14-17) An accidental predication, in which we have a substance in the place of predicate, is different from an essential predication in that while the subject of an accidental predication is said to be the predicate not by itself but as something different with which it coincides, the subject of an essential predicate is said to be the predicate by itself and not because it is something else: ‘Since there are attributes which are predicated of a subject essentially and not accidentally- not, that is, in the sense in which we say ‘That white (thing) is a man,’ which is not the same mode of predication as when we say ‘The man is white’: the man is white not because he is something else but because he is man, but the white is man because ‘being white’ coincides with ‘humanity’ within one subject. Therefore, there are terms such as are essentially subjects of predicates. (PsA., A, 19, 81a24-29) This capability of ‘non-essentially and only accidentally’ being a subject does belong, in fact, to all sensible things. (PsA., A, 27a32-36) d) Coincidental predication. this is a predication in which none of the subject and predicate are a substance or an individual. In this predication, one of the accidents of a substance or individual is predicated of one of the other accidentals of the same substance or individual. For example, when it is said that ‘The white is musical,’ there is an individual, say Socrates, for which both of white and musical are accidents. e) Absolute predication. This is a predication in which a form or a substance is predicated of a matter or a material substance. Some commentators like Loux and Lewis regarded this predication as close to accident predication, both based on inherence. As R.M. Dancy points out, these predications make Aristotle’s theory of predication immanentist: not only accident predications are explained by the immanence of accidents in substances, some of the substantial predications, which were not explained in Categories, are also explained by the immanence of form in matter. It is interesting that in this kind of predication, it is the predicate and not the subject, which is in the strictest sense substance. As the central books of Metaphysics claim, the form is the substance. Thus, in this predication, substance gets away from the sense of ὑποκείμενον. Corkum mentiones 68a19 as the only instance where Aristotle explicitly claims that a term may be predicated of itself, a passage that is, in Corkum’s view, problematic. 6) Demonstrable predicates Those predicates are demonstrable that are so related to their subjects that there are other predicates prior to them predicable of their subjects (ἔτι δ᾿ ἄλλος, εἰ ὧν πρότερα ἄττα κατηγορεῖται). (PsA., A, 22, 83b32-34) 7) Series of predications Since it is possible for a predicate to be itself the subject of another predication, we can have a series of predications in which the predicate of a predication is the subject of the next predication. This series has the following features: a) It has a limit (in number) (PsA., A, 22, 83b14-16) on the side of subjects: there are subjects that cannot themselves be predicated (PsA., A, 27, 43a39-41), which are, as we noted, prime subjects: particulars, i.e. prime substances and other individuals. (PsA., A, 19-22) Aristotle calls them ultimate (ὓστατον). (PsA., 21, 82a36-b1) b) It has a limit (in number of kinds) (PsA., A, 22, 83b14-16) also on the side of predicates: there must be predicates that cannot be subjects. (PsA., A, 19-22; PsA., A, 27, 43a36-39) Aristotle calls them primary (πρῶτον). (PsA., A, 21, 82b1-4) These are the highest categories or the highest genera of categories. (PsA., A, 22, 83b14-16) c) The series has an escalating shape from mere subjects at its downside to mere predicates at its upside. It is Aristotle himself whos uses the words up and down in this sense. (e.g. PsA., A, 22, 83b2-3) d) The predications that lie between lowest and highest ones must be finite in number. (PsA., A, 19-22 especially: 20, 82a21-35) These have subjects and predicates, each capable of both of the roles of being subject and being predicated. A result of this fitness is that neither demonstration can go to infinity nor everything is demonstrable, the two points Aristotle always insist on. e) The upward side includes the more universal ones and the downward the more particular ones. (PsA., 20, 82a21-23) f) It follows from the above features that ‘neither the ascending nor the descending series of predications … are infinite.’ (PsA., A, 22, 83b24-25) g) Reciprocation and convertibility. Except in case of terms (i.e. subjects and predicates) that are at each of the ends of series of predications, namely ultimates and primaries, it is possible to reciprocate (ἀντιστρέφειν) terms and convert the predication. (PsA., A, 19, 82a15-20) h) Antipredication. Antipredication means that in a predication (S is P), the subject becomes the predicate of its predicate (P is S) in the same category its predicate was predicated on it. For example, if P is in the category of quality, antipredication means that S be predicated of P in the category of quality. In other words, P is a quality of S and S is a quality of P. Aristotle rejects this. (PsA., A, 22, 83a36-b3) i) Self-predication versus other-predication. Aristotle distinguishes between a predication in which a term is said of itself and a predication in which a term is said of another. (Phy., Δ, 2, 209a31-33) j) Predicablity (Cat., 5, 3a36-b2): 1) Primary substances and individuals are not predicable. 2) Secondary substances are of two kinds: genus and species i) Genus is predicable able both of the species and of the individuals. ii) Species is predicable of the individual. 3) Differentiae are predicable both of the species and of the individuals. 8) Predication as classification a) Richard Patterson believes that Aristotle’s so repeated construction using hoper (estin A hoper B) in Topics (120a23 sq., 122b19, 26sq., 123a, 124a18, 125a29, 126a21, 128a35. Also in Posterior Analytics (83a24-30) (Brunschwig’s list. ‘expresses the fact that A is a kind of B (esti A B tis), that A is a species of the genus B.’ 9) Universal predication Aristotle defines universal predication (κατὰ παντὸς κατηγορεῖσθαι) as such: ‘wherever no instance of the subject (τῶν τοῦ ὑποκειμέμνου) can be found of which the other term cannot be asserted.’ (PrA., A, 24b27-29) In this predication, the subject is included in another as in a whole (ἐν ὃλῳ εἶναι) and the predicate is predicated of all of the subject (κατὰ παντὸς κατηγορεῖσθαι). (PrA., A, 24b26-27) Attach another discussion we had about ἐν ὃλῳ here. 10) Quantity of predication A predication, truly stated, has a quantity, which is the number of objects under the name of the subject of which the predicate is predicated. The quantity of subject can be stated in four ways: a. Indefinite: when the predicate belongs or does not belong to the subject without any mark to show to haw many of the particulars under the name of the subject it does or does not belong. E.g. ‘Man is white’; ‘Man is not white.’ (PrA., A, 24a20; OI., I, 7, 17b8-12) b. Universal quantity: When the predicate belongs to all or none of the subject. E.g. ‘Every man is animal’; ‘No man is animal.’ (PrA., A, 24a18-19; OI., I, 7, 17b5-6) The contrary of a predication of a universal quality is a predication of a universal quality. E.g. the contrary of ‘Every man is white’ is ‘No man is white.’ (OI., I, 7, 17b20-23) c. Particular quantity: When the predicate belongs (or does not belong) to some of the subject. E.g. ‘Some men are white’; ‘Some men are not white.’ (PrA., A, 24a19-20) d. Single quantity: when the subject is a proper name of only one object. E.g. ‘Socrates is white’; ‘Socrates is not white.’ The contrary of this predication is of a single quantity: ‘Socrates is not white.’ (OI., I, 7, 17b38-18a4) 11) Convertibility of predication. Some predications are convertible, that is, it is possible to change the place of subject and predicate in a true proposition so that the converted proposition remains true. This is supposed to mean that given the truth of a predication, the truth of the converted predication is inferable. The convert form of a predication depends on its quantity. a. Indefinite quantity: This predication has no strictly true convert because its quantity is not stated. b. Universal quantity: It can be converted in two ways: i) A negative universal can be converted to a negative universal in which the terms are changed. E.g. ‘No pleasure is good’ can be converted to ‘No good is pleasure.’ (PrA., A, 2, 25a5-8 and a14-19) ii) An affirmative universal can be converted to an affirmative particular in which the terms are changed. E.g. ‘Every pleasure is good’ can be converted to ‘Some good is pleasure.’ (PrA., A, 2, 25a7-9) c. Particular quantity: If it is negative, it cannot be converted but if it is affirmative, it can be converted to an affirmative predication with particular quantity. E.g. ‘Some pleasure is good’ can be converted to ‘Some good is pleasure.’ (PrA., A, 2, 25a10-13 and a20-24) d. Single quantity: It cannot be converted. 12) Characteristics of relations between subject and predicate 1. A predicate is of a wider range than its subject. It is based on this fact that Aristotle: a) Prevents individuals to be predicate because there is nothing of which an individual be of a wider range. In other words, it is due to the fact that since an individual is only ‘one particular’ thing and, thus, cannot be of a wider extent than anything that Aristotle prevents them of being a predicate. Matthews, however, thinks we cannot use Socrates, a substance and an individual, in the place of predicate and say it of Socrates because ‘Socrates does not classify Socrates: it names him.’ b) Prevents differentia, species and things under species to be predicated of genus. (To., Z, 6, 144a27-) c) Prevents the species and the things under it to be predicated of the differentia. (To., Z, 6, 144b1-4) d) Also about the effect because it is wider than its subject. (PsA., B, 17, 99a) e) Each attribute is wider than every individual it is predicated on, though several attributes, collectively considered, might not be wider but exactly the substance of a thing. (PsA., B, 13, 96a32-b1) 2. The predicate of a predicate of a subject will be predicated of the subject too: ‘whenever one thing is predicated of another as of a subject, all things said of what is predicated will be said of the subject too.’ (Cat., 3, 1b10-15) In fact, it is due to its predication of the subject that it is predicated of its predicate. (Cat., 5, 2a36-b1) Moreover, what is not predicated of the predicate of a subject cannot be predicated of it as well. (PrA., A, 27, 43b22-27) Thus, what, for example, is not predicated of animal, cannot be predicated of man. 3. The predicate of a subject can be predicated of its predicates as well. (Cat., 5, 3a1-6) For example, you call the individual man grammatical and, thence, you call both a man and an animal grammatical. Nonetheless, the predicate of a subject belongs to it more properly than to its higher predicates. (PrA., A, 27, 43a27-32) 4. It is only the subject that can be distributed and not the predicate. (PrA., A, 27, 43b16-22; OI, I, 7, 17b12-16) Therefore, we can say e.g. ‘Every man is animal’ but we cannot say ‘Every man is every animal.’ 5. It is the reason of the relation between subjects and predicates, that is the reason of predication, which is the subject of inquiry. (Met., Z, 1041a20-24) In other words, since it is a meaningless inquiry to ask why a thing is itself (Met., Z, 1041a14-15), the only remaining meaningful inquiry is to ask why something is something else, i.e. to ask about the reason of predication. 6. A subject cannot categorize its predicate in the same category in which it is categorized by it. If e.g. A is a quality of B, B cannot be a quality of A. Therefore, there is no reciprocation in the same category. (PsA., A, 22, 83a36-39) 13) Characteristics of series of predications 1. A series of secondary accidental predication cannot go ad infinitum for not even more than two terms can be comnbined. For an accident is not an accident of an accident, unless it be because both are accidents of the same subject. (Met., Γ, 1007b1-4) 2. Infinite series cannot be traversed in thought. (PsA., A, 22, 83b6-7) 3. The predications of genera on each other must be ended and cannot go to infinity because otherwise not only substances would not be definable but also a genus would be equal to one of its own species. (PsA., A, 22, 83b7-10) Therefore, a series of predication of genera on each other must be limited on both sides. There must be an upward limit in general categories as well as a downward limit in individual because they cannot be predicated of others. Whatever lies between these limits can both be predicated of others and others be predicated of them. (PrA., A, 27, 43a36-43) 4. The order of predicates matters: it makes a difference whether the series be ABC or BAC. (PsA., B, 13, 96b25-32) . (shrink)

Stať se snaží analyzovat myšlenky málo známého rukopisu Sigmunda Freuda z roku 1895, v němž usiloval o nalezení biologických základů lidské psychiky. Tato práce je pozoruhodná ze dvou důvodů. Jednak představuje úvahy, které se výrazně od- lišují od toho, co je pro Freuda v oblasti psychologie tak typické. Freud se zde, až na výjimky, nezabývá psychoanalýzou či studiemi o hysterii, nýbrž popisuje, co by mohlo být základem těchto psychologických jevů na neurofyziologické úrovni. Druhým pozoruhodným faktem je, že tento manuskript byl (...) pozapome- nut až do poloviny 20. století, kdy byl vytištěn pod názvem Projekt vědecké psychologie. A jak je známo, neurofyziologická studia lidské mysli spojená s analýzou kognitivních funkcí se v ri- gorózní podobě objevují až na počátku 60. let. Stať se proto pokouší ukázat základní principy Projektu a naznačit, v čem byl Freud inspirativním průkopníkem moderních neurofyziologických přístupů k lidské mysli. (shrink)

There are at least two discussions about Pythagoreans in Aristotle’s works that can be related to paradigm, both in Book A of Metaphysics. In the first, Aristotle says that for Pythagoreans all the things are modeled after numbers (τὰ μὲν ἄλλα τοῖς ἀριθμοῖς ἐφαίνετο τὴν φύσιν ἀφωμοιῶσθαι πᾶσιν). (Met., A, 985b32-33) In the second, Aristotle tells us that Pythagoreans take ‘the first subject of which a given term would be predicable (ᾧ πρώτῳ ὑπάρξειεν ὁ λεχθεὶς ὃρος)’ as the substance of (...) the thing. His example is double and two: since two is the first thing of which double is predicated, double will be the substance of two. (Met., A, 987a22-25) 1) Forms as paradigms Some of the critiques of platonic Forms in Aristotle’s works are paradigm-oriented: they attack Plato’s theory on the basis that Platonians considered Forms as paradigms. The core of all Aristotle’s objections is that calling Forms paradigms is a mere poetical strategy and does not have any real effect. (Met., 991a20-22; M, 1079b24-26) We can recognize four reasons for Aristotle’s objections of forms as paradigms: a) To consider something as the paradigm of another thing to which it is like does not have any ontological effect: ‘For what it is that works, looking to the ideas? Anything can either be, or become, like another without being copied from it, so that whether Socrates exists or not a man might come to be like Socrates.’ (Met., A, 991a22-26; M, 1079b26-29) Therefore, paradigms are ontologically unnecessary: ‘It is quite unnecessary to set up a form as a paradigm … the begetter is adequate to the making of the product and the causing of the form in the matter.’ (Met., Z, 1034a2-5) Don’t these cases imply that Aristotle did have more the ontological necessity of paradigm in thought instead of its epistemological necessity? b) To consider Forms as paradigms means that a thing must have several paradigms; e.g. animal and too-footed and man will be paradigms of the same thing. (Met., A, 991a27-29; M, 1079b31-33) c) The theory that Forms are paradigms not only of sensible things but also of themselves makes the same thing both a paradigm and a copy (ἐικών). (Met., A, 991a29-b1; M, 1079b33-35) 2) Reasoning by paradigm Aristotle compares the arguments using paradigms to his own theory of syllogism: ‘We have an ‘example’ (παράδειγμα) when the major term is proved to belong to the middle by means of a term which resembles the third. It ought to be known that the middle belongs to the third term, and that the first belongs to that which resembles the third. For example, let A be evil, B making war against neighbors, C Athenians against Thebians, D Thebians against Phocians. If then we wish to prove that to fight against Thebians is an evil, we must assume that to fight against neighbors is an evil. Evidence of this is obtained from similar cases, e.g. that the war against the Phocians was an evil to Thebians. …Now it is clear that B belongs to C and to D (for both are cases of making war upon one’s neighbors) and that A belongs to D (for the war against the Phocians did not turn out well for the Thebians); but that A belongs to B will be proved through D.’ (PsA., B, 24, 66b38-69a11) An ‘example’ can also be made by several similar cases. (PrA., B, 24, 69a11-13) Aristotle notes (PrA., B, 24, 69a13-24) that reasoning by paradigm is ‘neither like reasoning from part to whole nor like reasoning from whole to part but is rather a reasoning from part to part, when both particulars are subordinate to the same term, and one of them is known.’ And it differs from induction in two ways: a) While induction uses all the particular cases to prove that the major term belongs to the middle, reasoning by paradigm does not draw its proof from all the particular cases. b) While induction does not apply the syllogistic conclusion to the minor term, reasoning by paradigm does make this application. (PrA., B, 24, 69a13-24) . (shrink)

Sinema, genel olarak tüm sanat dalları, aynı anda hem bir sanat dalı ve politik-ekonomik bir kurumdur. Bir yanda elimizde hareketli imgeleri ışıkla selüloidden geçirerek ekrana yansıtan mecra film vardır. Tek tek filmler ise biçim ve içeriklerine göre birbirlerinden ayrılan ve analiz edilen münferit estetik objelerdir. Öte yanda ise film endüstrisi yer alır - filmleri planlayan, üreten, pazarlayan ve kitlelere izleten sanatsal, teknik ve ekonomik araçların oluşturduğu komplike ağ. Doğumundan bu yana sinemanın estetik ve politik açıları farklı formlarda birçok teorik analize (...) maruz kalmış, karşılığında bu analizler de çeşitli eleştirilerle irdelenmiştir. Bu metin bu analizlerin ve onlara yöneltilen eleştirilerin kısa bir incelemesini ve ardından film teorisine farklı bir yaklaşımın ana hatlarını sunacağım.

Discussione a partire dal libro di M. NICHTERLEIN e J. R. MORSS, Deleuze e la psicologia, a cura di Pietro Barbetta ed Enrico Valtellina, Raffaello Cortina, Milano 2017.

Com o propósito de analisar a relação entre ser e movimento a partir dos conceitos de ato e potência, elaboramos um mapeamento do livro Θ da Metafísica, capaz de orientar o entendimento de sua estrutura central. Visto como um dos modos de se dizer o ser, o ser em ato e em potência é parte integrante e fundamental da investigação metafísica. A distinção entre ser em ato e em potência pretende resolver o clássico problema do não-ser que vem a ser, (...) mostrando como o não-ser é apenas não-ser ainda em ato, mas já é ser em potência e este guarda as condições para sua necessária atualização. A reconstrução argumentativa de Θ procurou ressaltar três aspectos principais: (1) Ato e potência funcionam como um elemento de conexão entre as outras ciências – práticas, produtivas e teóricas – que são subordinadas à Ciência do Ser enquanto Ser, a Metafísica. (2) Há uma forte relação entre o par conceitual ato/potência e os outros conceitos fundamentais da filosofia aristotélica, tais como: substância, forma, matéria, ação, bem, natureza e fim. Desse modo, ato e potência somente serão plenamente compreendidos se também forem considerados esses outros conceitos. (3) Há uma relação direta entre os dois sentidos em que ato e potência podem ser entendidos - o cinético e o metafísico - e a seguinte divisão interna de Θ: de Θ1 a Θ5 a investigação está centrada sob o ângulo do movimento, é o momento cinético, em que Aristóteles dedica-se mais à análise da potência caracterizada como um princípio de movimento.

Por isso, é viável que todo e qualquer parto seja observado à distância seja pelo criador ou o trabalhador da propriedade, visando a possível ajuda no parto do animal caso o neonato passe por complicações na hora do nascimento. Um dos grandes vilões que aumentam o percentual de mortalidade de neonatos é as possíveis complicações na hora do nascimento, o animal pode ficar preso e morrer, como denomina-se de distorcia. Observe os fatores a serem levados em consideração no quadro abaixo. -/- Edema vulvar -/- Acúmulo anormal de muco na vagina -/- Distensão de ligamentos -/- O primeiro compartimento a se distender é a vagina para a facilitação da passagem do neonato -/- Edema abdominal e mamário -/- Acumulação de líquidos anormal no abdômen e no úbere -/- Gotejamento do colostro -/- 12 – 24 horas antes do parto -/- Inquietações -/- As vacas prontas pra parir ficam inquietas, hiperativas -/- Inapetência -/- As vacas cortam a alimentação por conta própria -/- Isolamento -/- As vacas que, normalmente andam em rebanho, se isolam em um determinado lugar para que possa parir -/- 8 CONSTANTES FISIOLÓGICAS -/- Essas constantes de temperatura, frequência cardíaca e respiratória além dos movimentos ruminais, servem de base para que o produtor mantenha seu rebanho sob controle veterinário e que, mediante quaisquer alterações nos dados apresentados, o produtor deverá comunicar ao médico veterinário da propriedade para que possam ser tomadas as devidas providências.

Recentes estudos em história da ciência têm apresentado indícios de que é impossível estabelecer uma clara distinção entre estudos de óptica e de perspectiva linear quando nos referimos aos séculos XVI e XVII. Embora a perspectiva linear lidasse com a representação geométrica do espaço numa superfície bidimensional, estava, entretanto, estreitamente ligada a questões relativas à natureza da visão humana. Devemos considerar que, naquela época, o termo perspectiva era a tradução latina da palavra grega optikè, denotando a visão direta e distinta (...) que, para os gregos, revelava as coisas. Seu significado coexistiu com outros que designavam a técnica pictórica e, para distingui-los, era comum opor a perspectiva "comum” ou “natural” à perspectiva artificialis dos pintores. Essas diferentes expressões de perspetiva relacionaram-se de diferentes maneiras, cobrindo um largo espectro de possibilidades. Contudo, à medida em que se encerrou o século XVI, essas duas expressões de conhecimento passaram, gradativamente, a se referir a diferentes disciplinas. Parte desse processo esteve ligado às novas práticas matemáticas em que a óptica, a geometria e as artes buscaram redefinir seus campos de investigação, considerando questões de ordem teórica ligadas à visualização e à representação do espaço. Neste artigo, apresentamos alguns aspectos da estreita conexão entre perspectiva naturalis e artificialis, tendo por base um conjunto de documentos relativos à óptica e à perspectiva linear publicado nos séculos XVI e XVII.

O objetivo dessa dissertação é discutir alguns conceitos que dizem respeito ao estatuto da eudaimonía, tendo como pressuposto que o texto da Ética a Nicômaco possa por si só esclarecer como ela é entendida por Aristóteles. Na minha hipótese, as discussões metodológicas estabelecidas no livro I servem como orientações suficientes para esclarecer a relação entre a realização da eudaimonía e o exercício das virtudes da alma, sem com isso haver a necessidade de que recorramos a outras obras de Aristóteles. Em (...) conseqüência dessa orientação, priorizei nessa pesquisa entender a afirmativa de Aristóteles de que a eudaimonía é um bem realizável pela ação do homem virtuoso, sendo um bem de caráter prático que consisti no exercício de um érgon, que é exclusivo ao homem; privilegiei então os conceitos relacionados à vida prática para o esclarecimento do que seja a eudaimonía, a relação entre as arētaí ēthikaí, a phrónesis e a sophía na sua realização, objetivando também, através dessa relação, entender as conexões entre lógos, práxis e páthos na realização do bem supremo do homem. Meu objetivo é pensar as relações entre a eudaimonía e as virtudes morais e intelectuais na Ética a Nicômaco; em conseqüência, compreender o lugar da vida prática e da vida teórica na realização da vida plena.

Felsefe Optiğinden Aşkın Renkleri kitabı Senail Özkan’ın bir takdim yazısı, giriş ve yedi bölümden oluşmaktadır. Kitapta kaynakçaya yer verilmemiştir. Halilov, kitabın giriş kısmında ‘aşk’ın ne olduğunu ve hangi ilim dalı tarafından ele alınması gerektiğini açıklamıştır. Ona göre aşk insanın manevi âleminin en derin katmanlarında ortaya çıktığı için temel itibariyle bilinçdışı alana aittir. İlim onu irdeleyemez, aşk, ilim için muğlak bir alandır ve mantıki düzlemde değerlendirilmesi oldukça zordur. İlim açısından incelenemediği için bu işi felsefe ve şiir üstlenmektedir.(s.16, s. 55) Şiir ve (...) aşk ilişkisine değinen Halilov, şiirin aşk ile büyük bir ilgisi olduğunu Doğu’da ve Batı’da aşk konusunun şiir sanatının kapsamı içinde değerlendirildiğini söyler. Doğu’da Nizami, İbn Arabi, Mevlana, Fuzuli, İkbal ve Cavid’e kadar Doğu şairlerinin aşk konusunu ele aldığı ve bununla ilgili eserler verdiğini ekler. Halilov’a göre Doğu’da aşk, ‘ilahi nitelikte’ ele alınmaktadır. Bütün kitap boyunca ‘ilahi aşk’ meselesi üzerinde duran Halilov bazen bu görüşü savunmuş bazen de tutarsız ve gerçek hayattan uzak olduğunu anlatmaya çalışmıştır. Ona göre aşk, ilahi olmaktan ziyade ferdi, bireysel veya insanidir. Aşk, ‘yerle gök arasında’ olması gerekmektedir. Bu açıdan Halilov aşkı, rasyonel bir düzlemde alan Batı öğretisini tercih ettiğini söylemektedir.(s.18) Fakat kitabına baktığımızda aslında Halilov’un bazı gerekçeler nedeniyle bu konuda biraz tereddütte kaldığını göreceğiz.

An increasing vaccine hesitancy among parents, which has resulted in insufficient rates of immunization, provides reason to reconsider childhood vaccination practices. Studies suggest that parents’ decision-making process concerning whether to vaccinate their child is highly influenced by cognitive biases. These biases can be utilized to increase vaccination uptake via changes in the choice context. This article considers childhood vaccination programmes, which involve children being vaccinated in school or daycare unless their parents actively “opt out”. We suggest that such programmes reconcile (...) parents’ decisional authority and vaccination duties. First, opt-out childhood vaccination based in schools or daycare centres are not disrespectful of parental authority. Second, the programme aligns the default setting with a moral obligation to vaccinate one’s child that most parents have. (shrink)

This paper evaluates the economic effects of a politically communitarian model of family ties towards the pension crisis in developing countries. The use of a Canadian - an individualist-oriented political economic pension system - is compared to a religiously and culturally communitarian form of family care in Bangladesh, a country slowly feeling the effects of the pension crisis. The analysis concludes, based on theoretical and economic evidence, that it is not in the social or economic interest of Bangladesh or similar (...) countries to use the same policies currently being deployed by Canada and most other OECD countries. This paper is the first of its kind to apply socioeconomic costs and benefits of developed countries’ policies and apply them to the context of a developing country—keeping in mind the cultural aspect and its implications. It aims at bringing back original ethical and moral values with a social orientation that should inspire all stakeholders to ensure family self-regulation that converge toward a solid foundation of communitarian principles.

We have a much better understanding of physics than we do of consciousness. I consider ways in which intrinsically mental aspects of fundamental ontology might induce modifications of the known laws of physics, or whether they could be relevant to accounting for consciousness if no such modifications exist. I suggest that our current knowledge of physics should make us skeptical of hypothetical modifications of the known rules, and that without such modifications it’s hard to imagine how intrinsically mental aspects could (...) play a useful explanatory role.

I defend the extremist position that the fundamental ontology of the world consists of a vector in Hilbert space evolving according to the Schrödinger equation. The laws of physics are determined solely by the energy eigenspectrum of the Hamiltonian. The structure of our observed world, including space and fields living within it, should arise as a higher-level emergent description. I sketch how this might come about, although much work remains to be done.

Some modern cosmological models predict the appearance of Boltzmann Brains: observers who randomly fluctuate out of a thermal bath rather than naturally evolving from a low-entropy Big Bang. A theory in which most observers are of the Boltzmann Brain type is generally thought to be unacceptable, although opinions differ. I argue that such theories are indeed unacceptable: the real problem is with fluctuations into observers who are locally identical to ordinary observers, and their existence cannot be swept under the rug (...) by a choice of probability distributions over observers. The issue is not that the existence of such observers is ruled out by data, but that the theories that predict them are cognitively unstable: they cannot simultaneously be true and justifiably believed.

Deep learning may transform health care, but model development has largely been dependent on availability of advanced technical expertise. The aim of this study is to develop a deep learning model to predict the gender from retinal fundus images. The proposed model was based on the Xception pre-trained model. The proposed model was trained on 20,000 retinal fundus images from Kaggle depository. The dataset was preprocessed them split into three datasets (training, validation, Testing). After training and cross-validating the proposed model, (...) it was evaluated using the testing dataset. The result of testing, the area under receiver operating characteristic curve (AUROC) of the model was 0.99, precision, recall, f1-score and accuracy were 99%, precision, recall, f1-score and accuracy were 96.83%, 96.83%, 96.82% and 96.83% respectively.. Clinicians are presently unaware of dissimilar retinal feature variants between females and males, stressing the importance of model explain ability for the prediction of gender from retinal fundus images. The proposed deep learning may enable clinician-driven automated discovery of novel visions and disease biomarkers. (shrink)

Cosmological models that invoke a multiverse - a collection of unobservable regions of space where conditions are very different from the region around us - are controversial, on the grounds that unobservable phenomena shouldn't play a crucial role in legitimate scientific theories. I argue that the way we evaluate multiverse models is precisely the same as the way we evaluate any other models, on the basis of abduction, Bayesian inference, and empirical success. There is no scientifically respectable way to do (...) cosmology without taking into account different possibilities for what the universe might be like outside our horizon. Multiverse theories are utterly conventionally scientific, even if evaluating them can be difficult in practice. (shrink)

Recent literature on Christian nationalism by sociologists of religion in the United States identifies a perceived novel phenomenon: the fusion of authoritarian governmental forms with Christianity. However, the socio-historical origin of this international trend has been left relatively unexplored. Therefore, the goal of this chapter is to create a single international account that lends itself to future comparative theoretical frameworks and analyses through the term "Christofascism." -/- The chapter can also be accessed on google books at the link included in (...) the description.

As inductive decision-making procedures, the inferences made by machine learning programs are subject to underdetermination by evidence and bear inductive risk. One strategy for overcoming these challenges is guided by a presumption in philosophy of science that inductive inferences can and should be value-free. Applied to machine learning programs, the strategy assumes that the influence of values is restricted to data and decision outcomes, thereby omitting internal value-laden design choice points. In this paper, I apply arguments from feminist philosophy of (...) science to machine learning programs to make the case that the resources required to respond to these inductive challenges render critical aspects of their design constitutively value-laden. I demonstrate these points specifically in the case of recidivism algorithms, arguing that contemporary debates concerning fairness in criminal justice risk-assessment programs are best understood as iterations of traditional arguments from inductive risk and demarcation, and thereby establish the value-laden nature of automated decision-making programs. Finally, in light of these points, I address opportunities for relocating the value-free ideal in machine learning and the limitations that accompany them. (shrink)

Waiting time is widely used in health and social policy to make resource allocation decisions, yet no general account of the moral significance of waiting time exists. We provide such an account. We argue that waiting time is not intrinsically morally significant, and that the first person in a queue for a resource does not ipso facto have a right to receive that resource first. However, waiting time can and sometimes should play a role in justifying allocation decisions. First, there (...) is a duty of fairness prohibiting line-cutting where a sufficiently just queue exists. Second, waiting time has several morally attractive features that can justify its incorporation into allocation schemes. Where candidates are in relevantly similar circumstances, allocating by waiting time is relatively efficient, maximizes distribution equality relative to other Pareto efficient distributions, and treats candidates fairly. The claim that allocation using waiting time is fair is controversial. Some have claimed that formal lotteries are a fairer way to select among equal beneficiaries. We argue that lotteries are no fairer than allocation based on waiting time when it is equiprobable how a prospective queue will be ordered. In practice, lotteries share many of the disadvantages of queues; which is fairer will depend on contingent features of the allocation scenario. The upshot is that first-come, first-served is in fact a just way to allocate resources in many of the cases where it seems pre-theoretically compelling, and waiting time has unique normative properties which frequently justify its incorporation into resource allocation schemes.

The genetic modification of pigs as a source of transplantable organs is one of several possible solutions to the chronic organ shortage. This paper describes existing ethical tensions in xenotransplantation (XTx) that argue against pursuing it. Recommendations for lifelong infectious disease surveillance and notification of close contacts of recipients are in tension with the rights of human research subjects. Parental/guardian consent for pediatric xenograft recipients is in tension with a child’s right to an open future. Individual consent to transplant is (...) in tension with public health threats that include zoonotic diseases. XTx amplifies concerns about justice in organ transplantation and could exacerbate existing inequities. The prevention of infectious disease in source animals is in tension with the best practices of animal care and animal welfare, requiring isolation, ethologically inappropriate housing, and invasive reproductive procedures that would severely impact the well-being of intelligent social creatures like pigs.

It seems natural to ask why the universe exists at all. Modern physics suggests that the universe can exist all by itself as a self-contained system, without anything external to create or sustain it. But there might not be an absolute answer to why it exists. I argue that any attempt to account for the existence of something rather than nothing must ultimately bottom out in a set of brute facts; the universe simply is, without ultimate cause or explanation.

We study the question of how to decompose Hilbert space into a preferred tensor-product factorization without any pre-existing structure other than a Hamiltonian operator, in particular the case of a bipartite decomposition into "system" and "environment." Such a decomposition can be defined by looking for subsystems that exhibit quasi-classical behavior. The correct decomposition is one in which pointer states of the system are relatively robust against environmental monitoring (their entanglement with the environment does not continually and dramatically increase) and remain (...) localized around approximately-classical trajectories. We present an in-principle algorithm for finding such a decomposition by minimizing a combination of entanglement growth and internal spreading of the system. Both of these properties are related to locality in different ways. This formalism could be relevant to the emergence of spacetime from quantum entanglement. (shrink)

One widely used method for allocating health care resources involves the use of cost-effectiveness analysis (CEA) to rank treatments in terms of quality-adjusted life-years (QALYs) gained. CEA has been criticized for discriminating against people with disabilities by valuing their lives less than those of non-disabled people. Avoiding discrimination seems to lead to the ’QALY trap’: we cannot value saving lives equally and still value raising quality of life. This paper reviews existing responses to the QALY trap and argues that all (...) are problematic. Instead, we argue that adopting a moderate form of prioritarianism avoids the QALY trap and disability discrimination. (shrink)

Effective Field Theory (EFT) is the successful paradigm underlying modern theoretical physics, including the "Core Theory" of the Standard Model of particle physics plus Einstein's general relativity. I will argue that EFT grants us a unique insight: each EFT model comes with a built-in specification of its domain of applicability. Hence, once a model is tested within some domain (of energies and interaction strengths), we can be confident that it will continue to be accurate within that domain. Currently, the Core (...) Theory has been tested in regimes that include all of the energy scales relevant to the physics of everyday life (biology, chemistry, technology, etc.). Therefore, we have reason to be confident that the laws of physics underlying the phenomena of everyday life are completely known. (shrink)

Many real-world agents recognise that they impose harms by choosing to emit carbon, e.g., by flying. Yet many do so anyway, and then attempt to make things right by offsetting those harms. Such offsetters typically believe that, by offsetting, they change the deontic status of their behaviour, making an otherwise impermissible action permissible. Do they succeed in practice? Some philosophers have argued that they do, since their offsets appear to reverse the adverse effects of their emissions. But we show that (...) they do not. In practice, standard carbon offsetting does not reverse the harms of the original action, nor does it even benefit the same group as was harmed. Standard moral theories hence deny that such offsetting succeeds. Indeed, we show that any moral theory that allows offsetting in this setting faces a dilemma between allowing any wrong to be offset, no matter how grievous, and recognising an implausibly sharp discontinuity between offsettable actions and non-offsettable actions. The most plausible response is to accept that carbon offsetting fails to right our climate wrongs. (shrink)

In this paper I defend the traditional interpretations of Kant’s Formula of a Law of Nature from recent attacks leveled by Faviola Rivera-Castro, James Furner, Ido Geiger, Pauline Kleingeld and Sven Nyholm. After a short introduction, the paper is divided into four main sections. In the first, I set out the basics of the three traditional interpretations, the Logical Contradiction Interpretation, the Practical Contradiction Interpretation and the Teleological Contradiction Interpretation. In the second, I examine the work of Geiger, Kleingeld and (...) Nyholm: these three commentators reject the traditional interpretations entirely, but I argue that this rejection is ill-founded. In the third and fourth, I take a detailed look at Furner’s work, work in which he seeks to revise (rather than reject) the traditional interpretations. I argue that, despite his more modest aims, Furner’s revision is also ill-founded. (shrink)

And yet future generations are utterly disenfranchised in (...) the world today: they cannot participate in our markets, our movements, or our civil society. This presents 21st Century philanthropists with a historically unprecedented opportunity to do good by protecting the long-term future. -/- The essays within are from the pioneers who have developed the intellectual foundations of longtermism, as well as the experts and advocates who are now putting it into practice. Readers will hear the case for longtermism from professors at the University of Oxford and Longview’s own founders; longtermist policy proposals from political philosophers, members of the House of Lords, and the All-party Parliamentary Group for Future Generations; the case for work on biosecurity, artificial intelligence, and climate change from leading experts; and the first ever essay on longtermist cultural change from the former Chief of Cabinet to the Finnish President. -/- Together, these essays chart the path forward toward maximising the good that we do for our grandchildren, our grandchildren’s grandchildren, and every generation beyond.

In this paper I argue that there would be no obligatory maxims if the only standards for assessing maxims were Kant’s universalizability tests. The paper is divided into five sections. In the first, I clarify my thesis: I define my terms and disambiguate my thesis from other related theses for which one might argue. In the second, I confront the view that says that if a maxim passes the universalizability tests, then there is a positive duty to adopt that maxim; (...) I also confront a close relative of this view. In the third, I confront the view that says that if a maxim does not pass the universalizability tests, then there is a positive duty to adopt the contradictory of that maxim. In the fourth, I confront two variations of the view that says that if a maxim does not pass the universalizability tests and an agent is deliberating about the action in the maxim, then the agent has a positive duty to adopt the contrary of that maxim. In the fifth, I confront the view that says that if an agent has adopted a maxim of ends, then the agent has a positive duty to universalize that end. I then wrap up the paper with some concluding remarks. (shrink)

Psychiatric patients sometimes ask where to draw the line between who they are – their selves – and their mental illness. This problem is referred to as the self-illness ambiguity in the literature; it has been argued that solving said ambiguity is a crucial part of psychiatric treatment. I distinguish a Realist Solution from a Constructivist one. The former requires finding a supposedly pre-existing border, in the psychiatric patient’s mental life, between that which belongs to the self and that which (...) belongs to the mental illness. I argue that no such border exists, and that attempts to find it might even render the felt ambiguity worse. Instead, any solution must be constructivist; the patient (and others) should deliberate and discuss what to identify with or not. I further argue that psychiatric patients need not see their mental illness as wholly distinct from themselves to avoid ‘identifying with their diagnoses' in a problematic way. Finally, we can excuse problematic behaviour by mentally ill people – in fact, we can do so in a more nuanced and constructive way – while rejecting the view that the mental illness is wholly distinct from the patient’s self.

In August 2021, Froese et al. published survey data collected from 2,543 respondents on their subjective experiences living under imposed social distancing measures during COVID-19 (1). The questionnaire was issued to respondents in the UK, Japan, and Mexico. By combining the authors’ expertise in phenomenological philosophy, phenomenological psychopathology, and enactive cognitive science, the questions were carefully phrased to prompt reports that would be useful to phenomenological investigation and theorizing (2–4). These questions reflected the various author’s research interests (e.g., technology, grief, (...) time). Between April 7th and July 31st, 2021, a second questionnaire with the same question set was issued to respondents of the original who had agreed to do a follow-up. This was intended to capture subjective reports of life under social distancing measures a year after the initial survey. By this time–depending on their country of residence and health status–respondents had potentially lived with repeated and prolonged lockdowns and a variety of other restrictions on their social lives. When taken together, Survey I and Survey II provide a cross-cultural and longitudinal dataset that allows for analysis of longer-term impacts of imposed social distancing measures on people’s experiences. For researchers working in diverse disciplines, this dataset offers a rich resource that reflects people’s reactions to the imposition of different social restrictions in different countries and over different time periods.

In Morality & Mathematics, Justin Clarke-Doane argues that it is hard to imagine being "a realist about, for example, the standard model of particle physics, but not about mathematics." I try to explain how that seems very possible from the perspective of a physicist. What is real is the physical world; mathematics starts from descriptions of the natural world and extrapolates from there, but that extrapolation does not imply any independent reality. -/- Submitted to an Analysis Reviews symposium on Clarke-Doane's (...)

Numerous societal issues, from climate change to pandemics, require public engagement with scientific research. Such engagement reveals challenges that can arise when experts communicate with laypeople. One of the most common frameworks for framing these communicative interactions is the deficit model of science communication, which holds that laypeople lack scientific knowledge and/or positive attitudes towards science, and that imparting knowledge will fill knowledge gaps, lead to desirable attitude/behavior changes, and increase trust in science. §1 introduces the deficit model in more (...) detail and shows that adhering to this model often fails to achieve its aims, which motivates the main question of this chapter: how can Ludwik Fleck’s theory of thinking collectives address the persistent problem of deficit approaches in science communication? I suggest that it can do so by exposing the deficit model’s implicit assumption of an expert-lay divide. Accordingly, §2 lays out Fleck’s theory and §3 contrasts it with contemporary debates about science communication. Following this descriptive work, §4 draws on Fleck’s ideas to make four concrete suggestions for further questioning the expert-lay divide. (shrink)

The primary aim of this chapter is to show that several missteps made by others in in their thinking about law as an artefact are due to misconceptions about the role of intentions in understanding law as an artefact. I first briefly recap my own contention that law is a genre of institutionalized abstract artefacts (put forth in The Functions of Law (OUP 2016) and subsequent papers), mostly following Searle’s understanding of institutions and Thomasson’s understanding of public artefacts. I highlight (...) the central place that this theory affords law’s functions, without requiring the theorist to say that possession or performance of the function is either necessary or sufficient for inclusion in the class of law. Some of the most common misunderstandings are exemplified in Brian Leiter’s paper ‘Legal Positivism about the Artifact Law’. He thinks that holding an intentionalist view of artefacts commits the theorist to privileging drafters’ intentions when interpreting law. (It doesn’t.) He also has confusions about the differences between artefact tokens and artefact types leading him to a problematically broad understanding of artefacts. Another problem can be seen in thinking that functional understandings of artefacts are vulnerable to the same problems that arise in functional explanations for biological systems. I go on to consider the work of Luka Burazin and Corrado Roversi, addressing worries that making intentionality central to artefacts implies too much conscious thought is required to make one, noting that several theories of intentionality do not require conscious thought in the execution of intentional action. While those who think a central place for intentionality threatens to leave us unable to explain customary law, this can be dealt with by noting the important distinction between customary rules and customary laws (where the latter requires a decision to enlist public aid in redressing violations). I claim that authors’ intentions are communicated requests for the artefacts’ audiences to see the artefacts as members of their putative kinds. Finally, I address the question of whether or not legal systems are themselves artefacts and institutions, given that they may or may not have been intentionally created. An early lawgiver might have created a legal system by accident in the process of handing down the first laws. I raise the possibility that we might want to impute intentionality to necessary by-products of artefact creation, seeing those by-products as artefacts as well. (shrink)
