Gottfried Leibniz embarked on a research program to prove all the Aristotelic categorical syllogisms by diagrammatic and algebraic methods. He succeeded in proving them by means of Euler diagrams, but didn’t produce a manuscript with their algebraic proofs. We demonstrate how key excerpts scattered across various Leibniz’s drafts on logic contained sufficient ingredients to prove them by an algebraic method –which we call the Leibniz-Cayley (LC) system– without having to make use of the more expressive and complex machinery of first-order (...) quantificational logic. In addition, we prove the classic categorical syllogisms again by a relational method –which we call the McColl-Ladd (ML) system– employing categorical relations studied by Hugh McColl and Christine Ladd. Finally, we show the connection of ML and LC with Boolean algebra, proving that ML is a consequence of LC, and that LC is a consequence of the Boolean lattice axioms, thus establishing Leibniz’s historical priority over George Boole in characterizing and applying (a sufficient fragment of) Boolean algebra to effectively tackle categorical syllogistic.

: To address the question “on what there is” raised by Quine, and to accomplish the task of comprehending exhaustively the many ontological units that populate the great province of Being, we propose as an alternative to Puntel’s ontology a new ontology designated as “Structural Ontology” (SO). Such ontology is based on systematic-structural theoretical foundations, but leads to a diverse view in which structured factual units, structural configurations (dynamics), as well as apparent ontological units (objects), all encompassed by the temporal (...) sub-dimension that interconnects them, understood as an internal sub-dimension of the macro-dimension of Being, co-subsist. In this sense, we begin by situating the ontological theme in current philosophical discussion from a Quinean perspective. We then present a concept of truth derived from our reading of puntelian philosophy, which will be the point of connection between language and the world. Subsequently, we show how from the concept of truth, after a brief foray into philosophical semantics, we arrive at the ontological field from the ontological categories of structure and ontological state. Finally, we outline, in its general features, our structural ontology, which includes its own ontological notions that give new directions to philosophical understanding of this great theme.

In this paper I discuss some problems with Aristotle’s characterization of lucky events as events which are “for the sake of something”. I argue that there is no special sense of the phrase “for the sake of something” when applied to lucky events. Qua event, a lucky event has come about for the sake of something and thus unqualifiedly belongs among things that come about for the sake of something. But qua lucky event, it has not come about for the (...) sake of that thing it has come about qua event, but it nevertheless is, or turns out to be, for the sake of something. (shrink)

The paper examines the account of the mortal parts of the human soul in theTimaeus. What is their nature? What is their relationship to the immortal part of the soul and its inner structure on the one hand, and to the body and its organs and their functioning on the other? Are they incorporeal or corporeal? What kind of movement do they have? In what sense precisely are they ‘another kind of soul’ ?

The author discusses Aristotle’s notion of deliberation and shows that it differs considerably from the model of deliberation as is common in contemporary discussions of free will and moral responsibility. As opposed to the contemporary model, Aristotle’s account does not require that the deliberator has any belief (or lack thereof) concerning the availability of possible courses of action. However, the action chosen by deliberation, before it is performed, is still contingent––i.e. such that it can both be and not be done––and (...) up to us. Moreover, the action’s being up to us can be seen as grounded in our having rational capacities that are necessarily two-sided. This might suggest that the agent can do otherwise than she has decided by deliberation. The author argues that this is not the case: after deliberation, or after forming the relevant desire, the agent can actualize only one arm of her two-sided capacity, and hence, she cannot act differently than as decided by deliberation. If it makes sense to say that she can act differently, it is only because there may occur, in the interval between deliberation and action, some other desire which takes over a role of the decisive factor.

Žádnému tématu – s výjimkou historie Anglie – nevěnoval David Hume více pozornosti než náboženství. Jak už to ale s Humovým filosofickým odkazem bývá, i jeho teorie náboženství byla podrobena celé řadě mnohdy naprosto protikladných interpretací – a právě těm bude věnována první část mého článku. Došlo totiž k pokusům představit jej jako teistu, fideistu, deistu, agnostika nebo ateistu. Ve druhé části budu obhajovat hypotézu, podle níž je úsilí zařadit Huma do jediného údajně správného výkladu liché, protože každá taková snaha (...) naráží na nepřekonatelné terminologické spory, interpretační potíže a argumentační pochybení. Nemusí nás ovšem zajímat, co si Hume ve skutečnosti o náboženství myslel, případně za jaký typ věřícího či nevěřícího se považoval. Mnohem přínosnější je pochopit, jakým způsobem Humova koncepce předchází a obohacuje současnou ateologii. Ve třetí části proto představím textovou evidenci z primárních pramenů, v nichž se Hume zabýval kritikou zjeveného i přirozeného náboženství, morálních i psychologických aspektů religiozity. Závěrem se krátce zamyslím nad Humovou koncepcí „pravého náboženství“ a jejím uplatněním v sekulární společnosti. (shrink)

In this paper I challenge the widespread assumption that the conditions for singular reference are more or less the same as the conditions for singular thought. I claim that we refer singularly to things without thinking singularly about them more often than it is usually believed. I first argue that we should take the idea that singular thought is non-descriptive thought very seriously. If we do that, it seems that we cannot be so liberal about what counts as acquaintance; only (...) perception will do. I also briefly discuss and reject semantic instrumentalism. Finally, I argue that while singular reference is cheap, singular thought comes only at a price. (shrink)

Myšlenkové experimenty jsou populárním argumentačním nástrojem ve vědě i filosofii. Jejich kritika ze strany naturalistických a experimentálních filosofů vedla k vytvoření deflačních a minimalistických koncepcí, které oslabují epistemickou sílu myšlenkových experimentů a smiřují je s empirismem. Cílem článku je ukázat, že tyto pokusy nepřekonávají hlavní problémy, se kterými se myšlenkové experimenty ve filosofii střetávají. Omezená lidská racionalita a představivost znemožňují experimentátorům řešit nereálné scénáře spolehlivým způsobem. Myšlenkové experimenty se ve filosofii používají jinak než ve vědě, protože ty pravé jsou obvykle (...) neuskutečnitelné a uzavřené vůči možnosti empirické falsifikace. Navíc jsou založeny na vadných analogiích a neoprávněně přenášejí důkazní břemeno. Persvazivní úspěšnost myšlenkových experimentů je velmi nízká, a proto nedokáží přispět k řešení filosofických problémů. Závěrem článku je, že nejběžnější druhy myšlenkových experimentů by měly být odstraněny ze souboru filosofických metod. (shrink)

In 2009, we celebrated the bicentennial of the birth of Charles Darwin and the sesquicentennial of the publication of his book The Origin of Species. This seems to be a good opportunity to evaluate the importance of Darwin’s work for the social sciences, mainly for philosophical anthropology. The aim of this paper is to discuss the traditional anthropocentric conceptions of man, which consider our biological species to be exceptional – qualitatively higher than other living organisms. Over the course of the (...) 20th century, philosophers have argued for the claim in a number of ways: man is supposed to be the only animal capable of laughter, love, thought or language. It has also been claimed that only members of Homo sapiens have free will, morality or religion. The paper refutes these arguments on the basis of contemporary studies by M. Davila Ross, H. Fischer, K. Arnold, K. Zuberbühler, G. Konopka, B. Libet, F. De Waal, M. Bekoff, P. Boyer, B. Hood, G. Paul and others. The author argues that the only differences between man and other animals are quantitative, and therefore the nature of humans should be studied using the methods of naturalized philosophy, with respect to the natural sciences.

From the temporal perspective, this article examines shifts in the productionof sociological knowledge. It identifies two kinds of rhythms of sociology: 1) that of sociological standpoints and techniques of investigation and 2) that of contemporary academic life and culture. The article begins by discussing some of the existing research strategies designed to "chase"high-speed society. Some, predominantly methodological, currents are explored and contrasted with the "slow" instruments of sociological analysis composed of different, yet complementary, modes of inquiry. Against this background, the (...) article stresses that it is through the tension between fast and slow modes of inquiry that sociology reproduces itself. The subsequent part explores the subjective temporal experience in contemporary academia. It is argued that increasing administration and auditing of intellectual work significantly coshapes sociological knowledge production not only by requiring academics to work faster due to an increasing volume of tasks, but also by normalizing time-pressure.The article concludes by considering the problem as to whether the increasing pace of contemporary academic life has detrimental consequences for the more organic reproductive rhythms of sociology.

n the first part of the paper I will present Pritchard’s approach to Wittgenstein’s notion of hinge commitments, which is essential to his solution to the closure-based sceptical arguments. And, in the second par of the paper, I will raise some concerns that I have regarding Pritchard’s non-belief reading of the hinge commitments. In the third and final part, I make some concluding remarks regarding Pritchard’s overall strategy to solve the closure-based sceptical paradox.

Traditionally, the so-called ‘redintegration experiment’ is at the center of the comments on the supposed Boyle/Spinoza correspondence. A. Clericuzio argued (refuting the interpretation by R.A. & M.B. Hall) in his influential publications that, in De nitro, Boyle accounted for the ‘redintegration’ of saltpeter on the grounds of the chemical properties of corpuscles and did not make any attempt to deduce them from the mechanical principles. By contrast, this paper claims that with his De nitro Boyle wanted to illustrate and promote (...) precisely his new Corpuscular or Mechanical Philosophy, and that he did significant attempts to explain the phenomena in terms of mechanical qualities. Boyle had borrowed the ‘redintegration experiment’ from R. Glauber and used it as a tool to prove that his philosophy was the right alternative for the Peripatetic and Paracelsian theory of qualities of bodies. Consequently, Clericuzio’s characterization of the Boyle/Spinoza controversy as a discussion between a strict mechanical philosopher and a chemist is problematic and should be revised. (shrink)

The term ‘heat’ originates from the Old English word hǣtu, a word of Germanic origin; related to the Dutch ‘hitte’ and German ‘Hitze’. Today, we distinguish three different meanings of the word ‘heat’. First, ‘heat’ is understood in colloquial English as ‘hotness’. There are, in addition, two scientific meanings of ‘heat’. ‘Heat’ can have the meaning of the portion of energy that changes with a change of temperature. And finally, ‘heat’ can have the meaning of the transfer of thermal energy (...) from a hotter to a colder system or body. By contrast, for the Ancients and Scholastics, ‘heat’ was a manifest, real quality of bodies and there was an ontological distinction between biological or innate heat (which was regarded as an innate principle of life for warm-blooded animals) and the physical manifest heat of external objects, which is potentially harmful. During the late Renaissance period, however, both views changed fundamentally and evolved - via the application of physical and mechanical analogies - into the foundations for today’s unified mechanistic theory of heat.

Filósofos como Jonathan Kvanvig (2003) e Duncan Pritchard (2010) tem argumentado que o entendimento é um estado epistêmico distinto do conhecimento com base no argumento da sorte epistêmica. Eles alegam que dado que o entendimento é compatível com sorte epistêmica e o conhecimento não, então esses estados epistêmicos são distintos. Com base nos autores Christoph Kelp (2017) e Kenneth Boyd (2018), será argumentado que esse argumento não é o suficiente para mostrar que o entendimento e conhecimento são estados epistêmicos distintos. (...) Primeiro, o tipo de cenário que Kvanvig e Pritchard desenvolvem é um cenário em que a sorte é compatível com conhecimento. Segundo, ao desenvolverem os cenários de sorte compatível com o entendimento, eles tomam o objeto avaliativo errado do entendimento. Ao desenvolvermos um cenário com o objeto avaliativo correto para o entendimento, conclui-se que o entendimento não é compatível com sorte epistêmica. (shrink)

Phenomenology and Quantum theory have defined themselves against the subject-object tradition of thought and against the modern objectivistic attempt to unify explanation of reality or being. Scientific technology and calculative way of thinking have prevailed over meditative and qualitative thinking in modern times. Despite scientific efforts to eliminate any inconsistency caused by metaphysical speculations and systems, in everyday life and science we encounter such phenomena which cannot be explained unambiguously and fully on the basis of purely conventional criteria. This paper (...) focuses on Bohr's framework of complementarity. The idea enables us exploring and describing a given phenomenon in such manner that we get adequate knowledge of the same phenomenon or subject of interest only by completing incompatible descriptions.

V dějinách filozofie se objevilo nespočetné množství snah překonat kognitivní nedostatečnost člověka. Většinový názor zněl, že zatímco vnější smyslové poznání podléhá nejrůznějším klamům, poznání vnitřní je mnohem jistější, či dokonce neomylné. Předpokládaná znalost sebe sama je ovšem iluzorní a stala se důvodem pro vznik mnoha chybných přístupů ke skutečnosti. Kniha se skládá ze tří částí. První kapitola se zabývá introspekcí, především jejím přijetím v dějinách filozofie a odmítnutím v psychologickém behaviorismu 20. století. Druhá kapitola pojednává o iluzornosti svobody rozhodování, která (...) je způsobena řadou nevědomých mechanismů, o jejichž fungování máme zatím jen dosti matnou představu. Ve třetí kapitole jsou domýšleny důsledky kauzálního determinismu pro etiku a právo, především ve smyslu odmítnutí koncepcí morální odpovědnosti a retributivní spravedlnosti. Autor se tak pokouší dokázat, že podstatná část názorů zdravého rozumu je chybná a měla by být nahrazena sadou nových, kompatibilních s dnešní vědou. (shrink)

Karl Polanyi's double movement is a dialectical process characterized by a continuous tension between a movement towards social marketization and a movement towards social protectionism. Notably, Polanyi condemns the former movement while defending the latter. Without using the term " double movement " , F.A Hayek's theory of social evolution acknowledges the same phenomenon but reaches different normative conclusions. While for Polanyi the marketization of society is a utopia with dystopian consequences, Hayek's evolutionary explanation of this dialectical process asserts that (...) there is no alternative to a market oriented society. Both authors defend that their favoured movement is the one that truly supports the continuity of life. This article compares the authors' normative readings of the double movement and concludes that, from an evolutionary perspective, Polanyi's conclusion possesses a robustness that Hayek's postulate lacks.

In the following interview, conducted by email between June 21 and July 2, 2020, Filipe Cahungo talks about his academic trajectory, Angolan philosophy and the relations – including tectonic ones – between Brazil and Angola. I hope that our dialogue can strengthen (on the intellectual and emotional levels) a relationship that already exists (on the historical and geological levels). I also hope that readers are not bothered by the fact that I use the Brazilian Portuguese spelling and he the (...) Angolan one. As Rafael Haddock-Lobo explained, it is only possible to philosophize in Portuguese. Not because Portuguese is a metaphysically privileged language. Not because we lexically distinguish between “being [ser]” and “being [estar]”, something that neither the French or the German languages do. It is only possible to philosophize in Portuguese for a much simpler reason: it is in our mother tongues, with their particular spellings, that we feel most comfortable. Filipe Miguel Mário Cahungo was born on August 13, 1992, in the province of Bengo, municipality of Dembos-Quibaxe. He attended the “Seminar of the Missionaries of the Divine Word” in Angola from 2010 to 2016. In 2013, he joined the Instituto Superior Dom Bosco, a unit attached to the Universidade Católica de Angola, where he attended studies in philosophy as a Seminarian of the Congregação dos Missionários do Mundo Divino. In 2017 he graduated in Philosophy at the Instituto Superior Dom Bosco – Universidade Católica de Angola. He is a member of the Organização Ondjango Filosófico (FILONORG). He investigates African philosophy, African theology and African spirituality, and is the author of several academic articles. (shrink)

The indisputable success of experimental science caused a division in philosophy at the turn of the 21st century. A substantial part of philosophers was inspired by ground-breaking writings of W. V. O. Quine and they followed philosophical naturalism that considers hypothetical-deductive method the most effective or the only way to acquire justified true beliefs. Other philosophers are worried about the hegemony of empirical sciences and warn against excessive ambitions of scientific methodology. Scientism or scientific imperialism is a point of view, (...) according to which there are no boundaries of scientific knowledge. According to its supporters, science can describe and explain what is to be described and explained. In my paper I will introduce some common ways how to define and criticize scientism and scientific imperialism. The aim is to demonstrate that criticism of scientism and scientific imperialism is based on the incorrect understanding of what scientific methodology is, how scientific knowledge emerges from natural cognition and in which ways science differs from its alternatives.

The use of teleological language in biology is burdened with many difficulties. Speakers in everyday and scientific discourse confuse functions with purposes and misunderstand functionality, finality, and intentionality. The paper is structured into three sections. In the first part the difference between Platonic supranatural and Aristotelian quasi-natural account of teleology will be explained, with examples from the history of philosophy of biology. The second part will present the Darwinian approach to etiology that constitutes a more sound alternative to the teleological (...) explanation. In the last section I will briefly introduce the teleological bias that is studied by developmental and cognitive psychologists. I believe that this psychological inclination is the real source of intuitive worldviews that are incompatible with contemporary science. (shrink)

Pseudovědecké teorie jsou uzavřeny vůči možnosti vyvrácení, ale s konspiračními teoriemi to tak jednoduché není, protože mnohé zprávy o konspiracích jsou pravdivé.

Článek se zabývá dějinami střetu mezi analytickou a kontinentální tradicí, který dominoval filozofii 20. století. I když obě tradice vzešly ze stejného intelektuálního prostředí a byly výrazně ovlivněny novokantovstvím, přesto se jejich vzájemné neporozumění postupem času prohlubovalo a při několika příležitostech situace přerostla v otevřené nepřátelství. V článku je popsáno deset nejzávažnějších konfliktů: Russell vs. Bergson, Schlick vs. Husserl, Carnap vs. Heidegger, Ryle vs. Heidegger, Popperova kritika pseudovědy, konference v Royaumont, Searle vs. Derrida, odhalení Heideggerovy nacistické minulosti, Derridův čestný doktorát (...) z Cambridge a Sokalův podvrh. Na počátku 21. století se ukazuje, že rozepře analytické a kontinentální filozofie se vyčerpala. Mnohem podstatnější je spor o samotnou metodologii filozofie, jenž se projevuje v rozhraní mezi naturalisticky a antinaturalisticky zaměřenými mysliteli. (shrink)

Semantics based on representational theories of mind has met challenges recently. Traditional accounts consider meaning as an entity with semantic properties, i.e. a mental object that denotes or represents a real-world object. The paper discusses ways of constructing meaning without representations, as shown in Rapaport’s syntactic semantics and Rosenberg’s eliminative theory of mind and language.

Para solucionar a questão “sobre o que há” levantada por Quine, e realizar a tarefa de compreender de forma exauriente as muitas unidades ontológicas que povoam a grande província do Ser, propomos como alternativa à ontologia punteliana, uma nova ontologia designada de “Ontologia Estrutural” (OE). Tal ontologia parte de bases teóricas sistemático-estruturais, mas desemboca em uma visão diversa em que co-subsistem unidades factuais estruturadas, configurações estruturais (dinâmicas), bem como unidades ontológicas aparentes (objetos), todas englobadas pela subdimensão temporal que as interconexiona, (...) compreendida esta como uma subdimensão (interna) da macrodimensão do Ser. Nesse sentido, começamos situando a temática ontológica na discussão filosófica atual a partir de uma chave quineana; prosseguimos apresentando um conceito de verdade derivado de nossa leitura da filosofia punteliana, o qual constituirá o ponto de ligação entre linguagem e mundo. Na sequência, mostramos como do conceito de verdade trazido à lume, após uma breve incursão na semântica filosófica, chegamos ao campo ontológico a partir das categorias ontológicas de estrutura e estado ontológico. Ao final, delineamos, em seus caracteres gerais, a nossa ontologia estrutural, compreensiva de noções ontológicas próprias que dão novos rumos à compreensão filosófica desta grande temática.

In Ancient Greece, when philosophy began, it included all the theoretical knowledge. But later, in the time of Aristotle, specialized sciences started to emerge and the scope of philosophy grew smaller and smaller. The question is what to do when philosophy has lost its competence to deal with any relevant topic. The paper discusses three possible views of the relation between philosophy and science: anti-scientism, conceptual analysis and naturalism. All these approaches deal with various disadvantages. For anti-scientism it is mainly (...) the inability to explain the unprecedented success of modern science. Proponents of conceptual analysis are confronted with Quine’s attack on analytic statements and its consequences for a priori truths. Finally, naturalistic philosophers might be threatened by hegemony of science and its universal application of hypothetico-deductive method. The worst scenario for naturalistic philosophers is not as bad as some worry. Philosophers can solve their traditional problems using the knowledge of well-established special sciences, even though they might play the role of high-end science journalists. (shrink)

Na závěr je uvedena možnost biosémiotické reinterpretace mimo-lidského sociálního rozumění na pozadí teorie umweltu. (shrink)

The demarcation of pseudoscience has been one of the most important philosophical tasks since the 1960s. During the 1980s, an atmosphere of defeatism started to spread among philosophers of science, some of them claimed the failure of the demarcation project. I defend that the more auspicious approach to the problem might be through the intellectual character of epistemic agents, i.e., from the point of view of vice epistemology. Unfortunately, common lists of undesirable character features are usually based on a priori (...) reasoning, and therefore might be considered artificial or too vague. When we base our position on contemporary behavioural sciences, we can see that the epistemic character of believers in pseudoscience is for the most part determined by two related factors. Firstly, these epistemic agents show a higher level of cognitive laziness. By this I mean an inability or unwillingness to engage in reflective thinking and a reluctance to account for counterevidence. Secondly, they yield more easily to metacognitive overconfidence. This can be broadly understood as so-called “knowledge illusion”, the inability to recognize one’s own intellectual limits. The deficiency usually stems from a misunderstanding of the division of cognitive labour and of the agent’s role in epistemic society. I find the proposed epistemological approach to pseudoscience crucial. Only if we understand the descriptive aspects of the problem, can we think of normative solutions to it. (shrink)

Příspěvek se zaměřuje na zavádějící příběh o tzv. kodaňské interpretaci kvantové mechaniky, již jako údajně nerozpornou či jednotnou vytvořili a sdíleli na základě tzv. kodaňského ducha kvantové teorie její tvůrci v roce 1927. Článek bude vycházet z role, kterou v tomto příběhu sehráli především N. Bohr a W. Heisenberg. První část příspěvku seznamuje s variacemi toho, co se v literatuře považuje za kodaňskou interpretaci.

In this paper, we show that there are some strong philosophical and exegetical reasons to argue that according to the view developed in the first chapter of Aristotle’s De Memoria, the objects of memory are non-present, or absent, things and events rather than our past acts of awareness of them. We argue that on Aristotle’s account, the objects of memory can be particulars or universals, perceptibles or intelligibles, and that all these kinds of things are past in the same sense, (...) namely, in the sense of previously having been present to the perceiver or knower. Aristotle’s claim that we remember that we previously learned or saw something is the description of how, rather than what, we remember. Keywords: Aristotle, memory, past, pathos, present. (shrink)

Disertační práce se zabývá problematikou připisování myšlení jiným entitám, a to pomocí imitační hry navržené v roce 1950 britským filosofem Alanem Turingem. Jeho kritérium, známé v dějinách filosofie jako Turingův test, je podrobeno detailní analýze. Práce popisuje nejen původní námitky samotného Turinga, ale především pozdější diskuse v druhé polovině 20. století. Největší pozornost je věnována těmto kritikám: Lucasova matematická námitka využívající Gödelovu větu o neúplnosti, Searlův argument čínského pokoje konstatující nedostatečnost syntaxe pro sémantiku, Blockův návrh na použití brutální síly pro (...) řešení imitační hry, Frenchova teorie subkognitivních informací a Michieho skepticismus ohledně možnosti umělého vědomí. Závěr práce zachycuje současný stav recepce Turingova testu a představuje pokusy o jeho praktickou realizaci, například v každoroční soutěži o Loebnerovu cenu. Autor práce zastává názor, že ani po více než šedesáti letech od uveřejnění Turingova paradigmatického eseje stále neexistují žádné vážné důvody pro zamítnutí jeho tvrzení. Tradiční komputační funkcionalismus možná není ideální teorií vysvětlující činnost myslí a jako slibnější se může jevit vývoj v neurálních vědách, ale Turingův test je přesto užitečným a snad i jediným nástrojem pro detekci inteligence u lidmi vytvořených strojů.

The semantic analysis of conditional sentences does not entirely align with their morphosyntactic structure. I substantiate this hypothesis with instances from both Czech and English that extend beyond conventional textbook examples. I also highlight that logicians and philosophers often make terminological errors when they disregard the insights from linguistic disciplines. Despite the early analytic philosophy’s emphasis on terminological precision, the practical application falls significantly short of this ideal. I firmly believe that a proper understanding of the morphosyntax and semantics of (...) conditional sentences is a prerequisite for their classification and analysis. In our pursuit of a comprehensive exploration of conditional clauses, we must also grapple with methodological challenges that delve into the very core of the philosophy of language. The primary issue revolves around the fact that two out of the three a priori methods in philosophy rely heavily on the analysis of conditional sentences: thought experiments and modal metaphysics.

Objective of the study: To analyze the costs and profits of sugarcane production regarding the cultural practices of sugarcane suppliers. Methodology/approach: This study positions itself in this gap by comparatively analyzing 6 types of cultural practices: unraveling, windrowing, application of correctives, herbicides, insecticides and fertilizers, with the option of two systems Fixed rate (TF) and Variable rate (TV). Originality/Relevance: Brazil is a world reference in sugarcane production, with the State of São Paulo being the largest Brazilian producer. However, for sugarcane (...) suppliers to maintain this activity there is a need to reduce production costs and increase profitability/ha. However, there is a theoretical-practical gap in the financial assessment (costs and profits) of different cultural practices inherent to sugarcane production. Main results: The results demonstrated that the costs of cultural practices represent more than 30% of the total sugarcane production costs. The TF system proved to be more cost-efficient in the following operations: correctives, herbicides and insecticides. In the application of fertilizers, the TV system, in broadcast mode, had the best result. Finally, the profit/ton was R$1.70, demonstrating a very low profit margin/ha given the risk of the activity. Theoretical/methodological contributions: The sample for this research comprised 55 sugarcane suppliers from the State of São Paulo, whose data were obtained through a survey. The comparative analysis was based on the difference in costs of cultural practices and the estimation of the level of certainty (profit/costs), analyzed through the cumulative frequency carried out through the Monte Carlo Simulation (SMC).

Morality can be adaptive or maladaptive. From this fact come polarizing disputes on the meta-ethical status of moral adaptation. The realist tracking account of morality claims that it is possible to track objective moral truths and that these truths correspond to moral rules that are adaptive. In contrast, evolutionary anti-realism rejects the existence of moral objectivity and thus asserts that adaptive moral rules cannot represent objective moral truths, since those truths do not exist. This article develops a novel evolutionary view (...) of natural law to defend the realist tracking account. It argues that we can identify objective moral truths through cultural group selection and that adaptive moral rules are likely to reflect such truths. (shrink)

Finding the demarcation criterion for the identification of scientific knowledge is the most important task of normative epistemology. Pseudoscience is not a harmless leisure activity, it can pose a danger to the functioning of liberal democratic societies and the well-being of their citizens. First, there is an outline of how to define science instrumentally without slipping into the detrimental heritage of conceptual essentialism. The second part is dedicated to Popper’s falsification criterion and the objections of its opponents, which eventually led (...) to the abandonment of “naïve” falsificationism. Then I present two promising solutions to the problem, namely the ostensive definition of pseudoscience and the cognitive research of pseudoscientific thinking. In conclusion, I suggest to further extend the typology of alternatives to science to include parascience. (shrink)

The article presents an ontological analysis of games. In every game one could distinct four constitutive elements: players, game rules, material substratum of the game and intentional world of the game. The last element correspond with make-believe quality of games. These are two kinds of acts of playing (creating the world of the game): performative and kinetic. The article presents an analysis of these two kinds of acts of playing and present the division of games (performative-based/kinetic-based) which is ontologically fundamental (...) and sets two radically different groups of games. Kinetic games are based on physical, kinetic aspect of the player’s bodies and material tools they use in the game. Performative games are based on transmission some pieces of information. This division enable us to indicate some non-trivial facts about games, like implicit presence of laws of physics in kinetic games or double character or rules in performative games. Interesting fact is that although these two groups of games are very different in the terms of kinds of acts of playing (and also kinds of effort connected with these acts) there is at least one performative-kinetic hybrid game – chessboxing.

W filozofii czasu Ingardena szczególną rolę odgrywa charakterystyka ontologiczna teraźniejszości. Należy do niej m.in. szczelinowość. Okazuje się, że pojęcie to można powiązać z koncepcją tzw. teraźniejszości pozornej (specious present). Opierając się ponadto na pewnych rozważaniach S. Lema oraz B. Ogrodnika wiążę różne wartości szczelinowości (trwania kwantu teraźniejszości), ze złożonością formalną budowy przedmiotów. Uogólnienie tych wyników umożliwia dopełnienie rozważań Ingardena nad szczelinowością – sformułowanie zarysu ontologicznej teorii względności trwania teraźniejszości.

In this paper, I discuss Aristotle's notion of rational powers as presented in his Metaphysics Θ.2 and Θ.5. I argue, first, that his account cannot serve as the model for explaining human rational actions in general. The role of rational powers is restricted to the explanation of arts and their exercises, including the exercises of knowledge through teaching. The exercises of character virtues do not follow the same pattern that is discernible in the exercises of rational powers. Second, I try (...) to show that the similarities between Aristotle's rational powers and powers as they are commonly understood in contemporary accounts of agency, especially regarding their two-sidedness and up-to-usness, are only superficial. Aristotle's rational powers are not genuinely two-sided, and their being up to the agent has nothing to do with the availability of alternative courses of action. (shrink)

In this paper I offer a close reading of Aristotle’s argument in the Nicomachean Ethics 3.5.1114a31–b25 and try to show that despite considerable interpretive difficulties, some clear structure can nevertheless be discerned. While Aristotle’s main concern in this passage is to refute the so-called asymmetry thesis – the thesis that virtue is voluntary, but vice is not – there is much more in it than just a dialectical encounter. Aristotle wants to respond to a more general objection, which has as (...) its target the voluntariness of both virtue and vice, and which is provoked by some of his ideas in EN 3.4 and 3.5. Further, I will try to show why Aristotle thinks that we are only co-causes of our dispositions. In my opinion, his reasons have nothing to do with compatibilist or incompatibilist considerations as they are commonly understood in modern philosophy. In particular, he does not want to argue that nature is aitios of our dispositions just as ourselves are. Rather, we are co-causes of our dispositions because we are causal origins of actions without which a certain good, which is the final cause of our actions and of our dispositions, cannot be achieved. Finally, I will try to show that Aristotle’s discussion implies that there is no more to the responsibility for dispositions than there is to the responsibility for actions. (shrink)
