It is always difficult to disentangle oneself from the changes in epoch-making cultural events that have taken place over several centuries. Freemasonry is an emblematic case. It was born around the seventeenth century and still exists in the twenty-first. The changes within it have been innumerable, showing that it is not a coherent and constant phenomenon in its evolution. There have been Masonic authors, of relevant presence in Western culture, who have nailed the fundamental principles of Masonic thought, of its (...) "doing" and of its "being": Gotthold Ephraim Lessing (1729 - 1781) and Johann Gottfried von Herder (1744 - 1803). Francesco Angioni explores the sometimes abyssal differences between a way of "thinking" about the Freemasonry of the two Authors and that of today. It is the critical research of understanding the differences between a Masonic thought built on solid foundations and the construction of multiple walls of composite architecture that is not characterized by a coherent project. ============== È sempre difficile districarsi tra i cambiamenti di eventi culturali epocali che si sono svolti nel corso di più secoli. La Massoneria è un caso emblematico. Essa nasce intorno al XVII secolo ed esiste ancora nel XXI. I cambiamenti al suo interno sono stati innumerevoli, palesando che non è un fenomeno coerente e costante nel suo evolversi. Ci sono stati Autori massonici, di rilevante presenza nella cultura occidentale, che hanno inchiodato i principi fondamentali del pensiero massonico, del suo "fare" e del suo "essere": Gotthold Ephraim Lessing (1729 – 1781) e Johann Gottfried von Herder (1744 – 1803). Francesco Angioni esplora le differenze talora abissali tra un modo di "pensare" la Massoneria dei due Autori e quello di oggi. È la ricerca critica di comprensione delle diversità tra un pensiero massonico edificato su solide fondamenta e la costruzione di molteplici mura di composita architettura che non si caratterizza per un progetto coerente.

In Germany, between the last decades of the 18th and the first decades of the 19th centuries, four fundamental figures of German and European culture emerged: Lessing the great playwright, Herder the promoter of the epistemological foundations of modern linguistics and of the emerging historical-social sciences, Goethe the supreme poet and novelist, and Fichte the eminent philosopher. They were all Freemasons and basic authors of Masonic thought. The most significant works of these authors have been chosen, which summarize the interpretative (...) modalities of the complex Masonic reality of the 18th century. The book analyses Lessing's five Dialogues for Freemasons, highlighting his austere vision in the search for the essence of Freemasonry. Of Herder's two Masonic Dialogues, the connotation in the sense of Humanity of a Freemasonry that leaves the Enlightenment to set out towards new goals of pure and spiritual thought is noted. Among Goethe's poetic works, two in particular highlight the depth of a Masonic thought pervaded by a sophisticated and modern hermeticism. Fichte's Lessons on Freemasonry are framed in his complex philosophical thought and in his complicated experience of Masonic life. ========== Nella Germania tra gli ultimi decenni del XVIII e i primi del XIX secolo emergono quattro figure fondamentali della cultura tedesca ed europea: Lessing il grande drammaturgo, Herder promotore delle basi epistemologiche della moderna linguistica e delle nascenti scienze storico-sociali, Goethe il sommo poeta e romanziere, Fichte l’eminente filosofo. Erano tutti Massoni e autori basilari del pensiero massonico. Di questi Autori sono state scelte le opere più significative che sintetizzano le modalità interpretative della complessa realtà massonica del ‘700. Nel libro si analizzano i cinque Dialoghi per Massoni di Lessing evidenziando la sua visione austera nella ricerca dell’essenza della Massoneria. Dei due Dialoghi massonici di Herder è rilevata la connotazione nel senso dell’Humanität di una Massoneria che esce dall’Illuminismo per avviarsi a nuove mete di pensiero puro e spirituale. Tra le opere poetiche di Goethe due in particolare evidenziano la profondità di un pensiero massonico pervaso di un sofisticato e moderno ermetismo. Le Lezioni sulla Massoneria di Fichte sono inquadrate nel suo complesso pensiero filosofico e nella sua complicata esperienza di vita massonica. (shrink)

La simbologia iniziatica raccoglie varie forme di simboli: quelli che appartengono a un’antica tradizione e che si ripresentano come una normalizzazione del passato in chiave modernizzata; quelli che derivano da un patto tra i membri della collettività iniziatica e che garantiscono l’unità del gruppo, che sono sincronici nell’ambito del gruppo stesso; quelli che hanno il senso di proiezione al superamento dei limiti gnoseologici del gruppo e dei suoi membri, sono tradizionali ma mediante il loro carattere di molteplicità semantica offrono nuove (...) opportunità gnoseologiche. Il silenzio non fa parte della prima categoria, perché non tutti i gruppi iniziatici antichi o tradizionali lo utilizzavano ritualmente o lo consideravano come simbolo e quindi non poteva avere una funzione normativa suscettibile di modernizzazione. Può essere momento cruciale del secondo quando viene ritualizzato nelle diverse fasi d’apprendimento sulla base di una pattuizione connessa alla creazione del rituale e costituendosi come uno dei fulcri sincronici del gruppo, assicurando la sua unitarietà. Può anche appartenere al terzo caso quando assume una veste tradizionale ma avendo una sua pluridimensionalità semantica, nella comunione del dicere e tacere pulsa di opportunità nuove per l’accrescimento iniziatico. Il silenzio nel contesto iniziatico è una forma linguistica specifica che caratterizza tutto il percorso degli iniziati. Questi elaborano all’interno del gruppo la sintassi del silenzio, la morfologia dei simboli espressi tacitamente, senza spiegare compiutamente i loro significati. Ogni simbolo, o segno in senso semiotico, ha delle diverse significazioni per le diverse fasi del percorso iniziatico. Ognuno appartiene a una diversa tipologia di rapporto con ciò a cui si riferisce: ha rapporto di “similarità” come il disegno di una squadra e compasso che illustra degli oggetti operativi, di “prossimità” quando manifesta l’operazione di misurazione e di relazione dei rapporti alla quale l’oggetto è destinato, di “concordanza” se rinvia all’oggetto dentro la cognizione di una regola architettonica. Il simbolo in quanto forma speciale di segno si manifesta (prima fase d’apprendimento), come nell’esempio, in modalità iconografico-descrittiva contenente un significato “dettato”. È una dictatio iniziatica da tenere nel silenzio di fronte al mondo essoterico , del quale l’iniziando è ancora permeato, la simbologia deve essere evocata senza esplicitarne i suoi intimi significati, la si descrive ma non la si espone compiutamente. È il valore evocativo, indeterminato e silenziato, che deve stimolare l’iniziando alla ricerca dei significati. L’indeterminazione del silenzio destruttura l’essoterico, il suo pensiero le sue categorie criteri e valori, porta al deserto dei significati essoterici come via all’ontologia del linguaggio iniziatico. È stadio di attesa, di rinvio a un mondo altro. Si sospettano dei significati che nella successiva fase incominciano a palesarsi in una dictatio più precisa, un dictamen funzionale a rappresentare il concetto di misurazione nelle sue plurime significanze ove la misura è assunta come astrazione simbolico-concettuale. Proseguendo, il segno in forma di oggetto si spoglia di ogni rimando fattuale ed esistenziale, di comunicazione di un’astrazione o ideazione concettuale e si smaschera nel suo essere “regola” iniziatica.

Initiatory symbology collects various forms of symbols: those that belong to an ancient tradition and that present themselves as a normalization of the past in a modernized key; those that derive from a pact between the members of the initiatory community and that guarantee the unity of the group, which are synchronized within the group itself; those that have the sense of projection to overcome the gnoseological limits of the group and its members, are traditional but through their character of (...) semantic multiplicity offer new gnoseological opportunities. Silence is not part of the first category, because not all ancient or traditional initiatory groups used it ritually or considered it as a symbol and therefore could not have a normative function susceptible to modernization. It can be a crucial moment of the second when it is ritualized in the different phases of learning on the basis of an agreement connected to the creation of the ritual and forming itself as one of the synchronic fulcrums of the group, ensuring its unity. It can also belong to the third case when it takes on a traditional guise but having its own multidimensional semantics, in the communion of saying and silent pulses of new opportunities for initiatory growth. Silence in the initiatory context is a specific linguistic form that characterizes the entire path of the initiates. Within the group, they elaborate the syntax of silence, the morphology of tacitly expressed symbols, without fully explaining their meanings. Each symbol, or sign in the semiotic sense, has different meanings for the different phases of the initiation process. Each one belongs to a different type of relationship with what it refers to: it has a relationship of "similarity" such as the design of a team and compass that illustrates operational objects, of "proximity" when it manifests the operation of measuring and relating the relationships for which the object is intended, of "concordance" if it refers to the object within the knowledge of an architectural rule. The symbol as a special form of sign manifests itself (first phase of learning), as in the example, in iconographic-descriptive mode containing a meaning "dictated". It is an initiatory dictatio to be kept in silence in front of the essoteric world, of which the initiating is still permeated, the symbolism must be evoked without making explicit its intimate meanings, it is described but not fully exposed. It is the evocative, indeterminate and silent value that must stimulate the initiating in the search for meanings. The indetermination of silence destructures the essoteric, its thought its categories, criteria and values, leads to the desert of essoteric meanings as a way to the ontology of initiatory language. It is a stage of waiting, of referral to another world. We suspect meanings that in the next phase begin to manifest themselves in a more precise dictatio, a functional dictamen to represent the concept of measurement in its multiple meanings where the measure is assumed as symbolic-conceptual abstraction. Continuing, the sign in the form of an object strips itself of any factual and existential reference, of the communication of an abstraction or conceptual ideation and unmasks itself in its being an initiatory "rule". It is assumed, therefore, that initiatory improvement passes through the understanding of the signs, an understanding that is increasingly deeper and more comprehensive and that is autonomous and independent of the signs of the exoteric world. With regard to the symbolic-initiatic language, learning, from the apprenticeship phase to the following phases, focuses on the study of the formal relationships of symbols within initiatory gnoseology, on the meanings inherent in symbols and on their relationship with the initiatory community.

Goethe, an important figure in 18th century German Freemasonry, developed a Masonic thought based on the assumptions of hermetic esotericism that influenced much of his poetic and scientific production. ===================Goethe importante figura della massoneria tedesca del XVIII secolo sviluppa un pensiero massonico fondato sui presupposti dell'esoterismo ermetico che influì su molta della sua produzione poetica e scientifica.

This chapter argues in favour of three interrelated points. First, I argue that demonstration (as expression of scientific knowledge) is fundamentally defined as knowledge of the appropriate cause for a given explanandum: to have scientific knowledge of the explanandum is to explain it through its fully appropriate cause. Secondly, I stress that Aristotle’s notion of cause has a “triadic” structure, which fundamentally depends on the predicative formulation (or “regimentation”) of the explanandum. Thirdly, I argue that what has motivated Aristotle to (...) choose the syllogism as a demonstrative tool was precisely the fact that syllogisms are apt to express causal relations in their triadic structure. Instead of complaining against Aristotle’s preference for the syllogisms as demonstrative tools, I argue that Aristotle was fully aware of the advantages of regimenting the explanandum into a predication. One of these advantages is to abandon a purely extensional standpoint and to highlight the importance of the notion of relevancy in explanation. (shrink)

This paper discusses some issues concerning the definition of moral virtue in Nicomachean Ethics 1106b 36- 1107a 2. It is reasonable to expect from a definition the complete enumeration of the relevant features of its definiendum, but the definition of moral virtue seems to fail in doing this task. One might be tempted to infer that this definition is intended by Aristotle as a mere preliminary account that should be replaced by a more precise one. The context of the argument (...) Aristotle develops in Book II of his NE give us some help. I argue that the definition of moral virtue, once considered in the light of its context, is far from being an incomplete and provisional account: it rather introduces coherently the same notion of moral virtue that Aristotle employs in other texts (as in Nicomachean Ethics VI 13). My main proposal is that the way in which "hexis" is understood in the context of previous chapters allows Aristotle to encode in it the notion of an ability to do the right things regularly. Thus, moral virtue is a "hexis prohairetike etc.", but the ability to do the right things regularly is already encoded in the occurrence of "hexis" in the definiens account of moral virtue, as if Aristotle meant "hexis [praktike] prohairetike". (shrink)

I argue that Topics VI does not contain any serious theory about definitions, but only a collection of advices for formulating definitions in a dialectical context, namely, definitions aiming to catch what the opponent means. Topics VI is full of inconsistencies that can be explained away by this approach: the inconsistencies reflect "acceptable opinions about definitions" that distinct groups of interlocutors accept. I also argue that the "topoi" need not be pieces of serious theory Aristotle is commited to. The "topoi" (...) must also be considered as "endoxa", namely, as accepted opinions about how it is legitimate to draw an inference. (shrink)

In Prior Analytics I.30, Aristotle seems too much optmistic about finding out the principles of sciences. For he seems to say that, if our empirical collection of facts in a given domain is exhaustive or sufficient, it will be easy for us to find out the explanatory principles in the domain. However, there is a distance between collecting facts and finding out the explanatory principles in a given domain. In this paper, I discuss how the key expression in the sentence (...) at 46a25 should be interpreted: “the true characteristics of things” (“τῶν ἀληθῶς ὑπαρχόντων τοῖς πράγμασιν”). I argue that, on a more accurate interpretation of the expression, Aristotle’s point would cease to look like a piece of naïve or even silly optimism. (shrink)

This paper discusses the following question: why was the term “dunatos” (“possible”) employed by Aristotle as an alternative label for imperfect syllogisms in his discussion of assertoric syllogistic? My answer ascribes to Aristotle a bottom up perspective, in which he stresses what is necessary in the premise-pairs to attain target conclusions of a given form within a given figure. I argue that “dunatos” is employed by Aristotle to stress that an imperfect syllogism is always one of the possible options to (...) attain a conclusion of a given form within a given figure. I also argue that this picture sheds some light on Aristotle’s clarifications of the final clause in his definition of syllogism. (shrink)

Eu examino cada meandro do esforço de Aristóteles identificar vários usos de termos filosóficos essenciais em sua Metafísica, V.9-17.

Translation of Aristotle's Parts of Animals Book I into Portuguese, with full commentaries.

I discuss a short string of five sentences in Metaphysics V.5, 1015b6-9 relating demonstration to necessity. My proposal is that Aristotle focuses his attention on the demonstration as a demonstration. Other interpretations reduce the necessity in question to the modality of the component sentences of the demonstrations (the conclusion and the premises). My view does not deny that the modality of the component sentences is important, but takes seriously the idea that a demonstration itself should be understood as necessary—as not (...) capable of being otherwise. A demonstration cannot be different from what it is in the sense that [i] its components cannot be different from what they are, [ii] its components must be related to each other exactly in the way they are related. Demonstrations aim at the fully appropriate explanation of a given explanandum—and each demonstration is individuated by the explanandum it takes. Thus, the basic idea is that, for the target explanandum that individuates a given demonstration, the premises delivering the fully appropriate explanation cannot be replaces with different ones. I show how this proposal, which explains Aristotle’s language in 1015b6-9 accurately, does not make demonstrations ‘melt down into conditional necessity’, first, because the modality of the component sentences is still importantly involved, second, because the explanatory relation expressed in a demonstration is a necessary fact in the real world, so that the demonstration itself is also necessary (in the way I have explained) inasmuch as it captures that fact.

Translation of Aristotle's Physics I-II into Portuguese, with commentaries. Tradução para o português dos livros I e II da Física de Aristóteles, com comentários.

My object is Aristotle's discussion of principle of non-contradiction in the first stretch of Metaphysics IV.4. My main focus rests on the connections between Aristotle's discussion of the principle and some key notions of his (explicit or implied) semantics.

I discuss in this paper Aristotle’s definition of nature in Physics 192b 20-23. I intend to prove that this definition has to be taken as a set of three (not only two) conditions: the first condition just establishes that nature is a sort of cause; the second condition concerns the relationship between nature and the natural thing that has it as a cause; the third condition concerns the relationship between nature and the properties that natural things have from nature’s causality.

I discuss some of Aristotle’s scattered remarks from which one can construct his conception of matter. Aristotle seems to oscillate between two conceptions: one in which matter is the principle of becoming, another in which matter is a constituent element with no contribution for processes of becoming. Sometimes Aristotle takes matter as a thing independent in itself, and the correlated form is a feature that does not contribute to the matter’s essence, nor is a necessary condition for its existence. But (...) sometimes Aristotle takes matter as a constituent element the existence of which depends on the whole thing it is the matter of. These different approaches to matter seem to suggest an inconsistent theory of matter. However, I argue that, quite to the contrary, Aristotle has a consistent theory about matter. One of my main points is to distinguish contexts in which Aristotle is indeed talking about matter in general from contexts in which he uses the term “matter” to refer to a given thing that was previously taken as matter and to talk about that thing not qua matter, but qua the thing it is.

These are the commentaries (or notes) for Aristotle's Metaphysics V (Delta) 18-30. This file must be read together with the translation into Portuguese, which has been published as a different item, with a different DOI. In the Introduction, I discuss many issues about Aristotle's jargon, Aristotle's style and Aristotle's awareness of many philosophical problems that nowadays we locate within the branch Philosophy of Language.

This is an introductory handbook for some of the main themes around the notion of predication in Aristotle. It does not aim at being exhaustive, but only sketches some important lines about the subject; it contains an introductory essay, besides the translation (into Portuguese) and commentary of basic texts (such as Posterior Analytics I-22, Categories 1-5, Interpretation 1-6 etc.).

Aristotle contrasts episteme and doxa through the key notions of universal and necessary. These notions have played a central role in Aristotle’s characterization of scientific knowledge in the previous chapters of APo. They are not spelled out in APo I.33, but work as a sort of reminder that packs an adequate characterization of scientific knowledge and thereby gives a highly specified context for Aristotle’s contrast between episteme and doxa. I will try to show that this context introduces a contrast in (...) terms of explanatory claims: on the one hand, episteme covers those claims which capture explanatory connections that are universal and necessary and thereby deliver scientific understanding; on the other hand, doxa covers the explanatory attempts that fail at doing so. (shrink)

I discuss what Aristotle means when he say that scientific demonstration must proceed from necessary principles. I argue that, for Aristotle, scientific demonstration should not be reduced to sound deduction with necessary premises. Scientific demonstration ultimately depends on the fully appropriate explanatory factor for a given explanandum. This explanatory factor is what makes the explanandum what it is. Consequently, this factor is also unique. When Aristotle says that demonstration must proceed from necessary principles, he means that each demonstration requires the (...) principle that is the necessary one for the fully appropriate explanation of its explanandum. This picture also provides a key to understand Aristotle's thesis that scientific explanation depends on essences: it is the essence of the attribute to be explained that should be stated as the fully appropriate explanatory factor.

Trata-se de tradução do Hípias Maior de Platão para o Português, com algumas notas de elucidação e justificação das opções.

This book discusses Aristotle’s notions of essence and substance as they are developed in Metaphysics ZH. I examine Aristotle's argument at length and defends an unorthodox interpretation according to which his motivation is to provide an answer against a conflation between criteria for existential priority (delivering substances as primary beings) and criteria for explanatory priority (delivering essences as primary principles).

I have two aims in this paper. First, I argue that, in Aristotle’s theory of the four causes, there is a basic and common feature by which all causes are causes: they all work in a triadic framework in which they explain why a given attribute holds of a given underlying thing. Secondly, I argue against a version of “compatibilism” according to which each kind of cause is complete in its own domain and does not compete with any other kind. (...) I claim that there are priority relations according to which some kinds of cause are subordinated to others, even if these relations do not hold in every cases. (shrink)

I discuss the exact meaning of the thesis according to which the object of scientific knowledge is necessary. The thesis is expressed by Aristotle in the Posterior Analytics, in his definition of scientific knowledge. The traditional interpretation understands this definition as depending on two parallel and independent requirements, the causality requirement and the necessity requirement. Against this interpretation, I try to show, through the examination of several passages that refer to the definition of scientific knowledge, that the necessity requirement specifies (...) more exactly the causality requirement: what cannot be otherwise is the explanatory relation between the explanandum and the cause by which it is what it is. (shrink)

I discuss the argument Aristotle ascribes to Parmenides at Physics 186a23-32. I discuss (i) the reasons why Aristotle considers it as eristic and inconclusive and (i) the solution (lusis) Aristotle proposes against it.

I discuss in this paper the six requirements Aristotle advances at Posterior Analytics A-2, 71b20-33, for the premisses of a scientific demonstration. I argue that the six requirements give no support for an intepretation in terms of “axiomatization”. Quite on the contrary, the six requirements can be consistently understood in a very different picture, according to which the most basic feature of a scientific demonstration is to explain a given proposition by its appropriate cause.

I discuss Aristotle's treatment of essence and definition in Metaphysics VII.4. I argue that it is coherent and perfectly in accord with its broader context. His discussion in VII.4 offers, on the one hand, minimal criteria for what counts as definition and essence for whatever kind of object, but also, on the other hand, stronger criteria for a primary sort of definition and essence—and thereby it serves the interest of book VII in pointing to the explanatory power of the essence (...) of composite substances. (shrink)

At some point in the Incessu Animalium, Aristotle appeals to some geometrical claims in order to explain why animal progression necessarily involves the bending (of the limbs), and this appeal to geometrical claims might be taking as violating the recommendation to avoid “kind-crossing” (as found in the Posterior Analytic). But a very unclear notion of kind-crossing has been assumed in most debates. I will argue that kind-crossing in the Posterior Analytics does not mean any employment of premises from a discipline (...) other than that to which the explanandum belongs. Kind-crossing was meant to cover a specific sort of employment of premises from a different discipline, namely, the case in which premises from a discipline X are taken as the most important explanatory factor that delivers the fullest appropriate explanation of an explanandum within discipline Y. If this is so, the employment of geometrical premises in the Incessu Animalium is not an instance of the prohibited kind-crossing, but something that is in line with the theory of the Posterior Analytics.

This paper discusses the contrast between scientific knowledge and opinion as it is presented by Aristotle in Posterior Analytics A.33. Aristotle's contrast is formulated in terms of understanding or not understanding some "necessary items". I claim that the contrast can only be understood in terms of explanatory relevance. The "necessary items" are middle terms (or explanatory factors) that are necessary for the fully appropriate explanation. This approach gives a coherent interpretation of each step in the chapter.

I discuss the notion of education or educatedness (paideia) involved in the ‘educated human being’ (pepaideumenos), which Aristotle presents at the beginning of his Parts of Animals and a few other passages. The competence of educated human beings makes them able to evaluate some aspects of the explanations in a given domain without having a determinate knowledge about the specific subject-matter in that domain. I examine how such a competence is possible and how it is related to other critical abilities (...) which Aristotle usually ascribes to the science of being qua being. Discuto a noção de educação ou cultura (paideia) envolvida na figura do ser humano cultivado (pepaideumenos), que Aristóteles apresenta no início do tratado As Partes dos Animais e em algumas outras passagens. A competência do ser humano cultivado o habilita a avaliar certo aspecto das explicações propostas em um dado domínio, sem requerer dele um conhecimento determinado sobre o assunto específico do mesmo domínio. Examino de que modo essa competência é possível e como ela se articula a outras habilidades críticas que Aristóteles geralmente associa à ciência do ser enquanto ser. (shrink)

I examine Aristotle’s definition of scientific knowledge in Posterior Analytics 71b 9-12 and try to understand how it relates to the sophistical way of knowing and to "kata sumbebekos knowledge". I claim that scientific knowledge of p requires knowing p by its appropriate cause, and that this appropriate cause is a universal (katholou) in the restricted sense Aristotle proposes in 73b 26-27 ff., i.e., an attribute coextensive with the subject (an extensional feature) and predicated of the subject in itself (an (...) intensional feature). Kata sumbebekos knowledge, on the other hand, can occur even when the predicate of a conclusion is coextensive with its subject and is proved by a convertible meson which is not the most appropriate from an explanatory standpoint.

Translation of Aristotle's Metaphysics IV and VI, with notes. The translation is preliminary and intended as a provisional teaching tool to be also used in seminars and discussions with peers in order to reach a more elaborated version.

In Posterior Analytics 71b9 12, we find Aristotle’s definition of scientific knowledge. The definiens is taken to have only two informative parts: scientific knowledge must be knowledge of the cause and its object must be necessary. However, there is also a contrast between the definiendum and a sophistic way of knowing, which is marked by the expression “kata sumbebekos”. Not much attention has been paid to this contrast. In this paper, I discuss Aristotle’s definition paying due attention to this contrast (...) and to the way it interacts with the two conditions presented in the definiens. I claim that the “necessity” condition ammounts to explanatory appropriateness of the cause. (shrink)

I discuss Aristotle's anomalous terminology in Physics A.1 (involving "universals" and "particulars") and its coherence with Aristotle's notion of scientific demonstration.

This is an Editorial Note for the special volume of the journal Manuscrito (42: 4) devoted to Aristotle's theory of demonstration and its logical and metaphysical entanglements, which has been organized by me and Breno Zuppolini (as Guest Editors), with papers authored by Benjamin Morison, Owen Goldin, David Bronstein, Michail Peramatzis, Andrea Falcon, Laura Castelli, Paolo Fait, Joseph Karbowski, Adam Crager, Klaus Corcilius, Robert J. Hankinson, Raphael Zillig and Pieter Sjoerd Hasper.

This chapter discusses the first part of Aristotle's Posterior Analytics A-33, 88b30-89a10. I claim that Aristotle is not concerned with an epistemological distinction between knowledge and belief in general. He is rather making a contrast between scientific knowledge (which is equivalent to explanation by the primarily appropriate cause) and some explanatory beliefs that falls short of capturing the primarily appropriate cause.

This paper attempts to clarify the nature and the importance of a third kind of sophistic argument that is not always found in the classification of those arguments in the secondary literature. An argument of the third kind not only is a valid one, but is also constituted of true propositions. What makes it a sophistic argument is the fact that it produces a false semblance of scientific explanation: its explanation seems to be appropriate to the explanandum without being so. (...) Evidence from this kind of argument comes from Sophistic Refutations 11, and Brison’s attempt to square the circle should be counted as one of its instances. (shrink)

I discuss the issue whether Aristotle's philosophy of science allows the use of mathematical premises or mathematical tools in general for explanaing phenomena in the natural sciences. I thereby discuss the concept of "metabasis eis allo genos" as it appears in Posterior Analytics I.7.

I discuss an important feature of the notion of cause in Post. An. 1. 13, 78b13–28, which has been either neglected or misunderstood. Some have treated it as if Aristotle were introducing a false principle about explanation; others have understood the point in terms of coextensiveness of cause and effect. However, none offers a full exegesis of Aristotle's tangled argument or accounts for all of the text's peculiarities. My aim is to disentangle Aristotle's steps to show that he is arguing (...) in favour of a logical requirement for a middle term's being the appropriate cause of its explanandum. Coextensiveness between the middle term and the attribute it explains is advanced as a sine qua non condition of a middle term's being an appropriate or primary cause. This condition is not restricted either to negative causes or to middle terms in second‐figure syllogisms, but ranges over all primary causes qua primary. (shrink)

Tradução para o Português de Ethica Nicomachea VI.

We outline a neo-Meinongian framework labeled as Modal Meinongian Metaphysics (MMM) to account for the ontology and semantics of fictional discourse. Several competing accounts of fictional objects are originated by the fact that our talking of them mirrors incoherent intuitions: mainstream theories of fiction privilege some such intuitions, but are forced to account for others via complicated paraphrases of the relevant sentences. An ideal theory should resort to as few paraphrases as possible. In Sect. 1, we make this explicit via (...) two methodological principles, called the Minimal Revision and the Acceptability Constraint. In Sect. 2, we introduce the standard distinction between internal and external fictional discourse. In Sects. 3–5, we discuss the approaches of (traditional) Meinongianism, Fictionalism, and Realism—and their main troubles. In Sect. 6 we propose our MMM approach. This is based upon (1) a modal semantics including impossible worlds (Subsect. 6.1); (2) a qualified Comprehension Principle for objects (Subsect. 6.2); (3) a notion of existence-entailment for properties (Subsect. 6.3). In Sect. 7 we present a formal semantics for MMM based upon a representation operator. And in Sect. 8 we have a look at how MMM solves the problems of the three aforementioned theories. (shrink)

I discuss three kinds of relationship between ends and means (or "things that promote ends") in the Aristotelian ethical theory, in order to clarify how moral virtues and phronesis are related both in adopting ends and in determining means for virtuous actions. Phronesis seems to be mainly charged with determining means for an end given by the moral virtues, but it must involve some conception of ends too. Phronesis cannot be parasitic on moral virtue concerning the conception of ends, for (...) otherwise it will lack intrinsic moral value. I argue that the intrinsic moral value of phronesis can be better understood through a certain kind of relation between means and ends that has not received much attention. (shrink)

Collective volume with papers by alumni and students from the Campinas Aristotle Group.

I argue that Aristotle’s teleology in natural science (more specifically, in biology) is not incompatible with his admissions of the “brute necessity” of the movements of matter. Aristotle thinks that the brute necessity emerging from the movements of matter is not sufficient to explain why living beings are what they are and behave the way they behave. Nevertheless, Aristotle takes this brute necessity to be a sine qua non condition in biological explanations. The full explanation of the features of living (...) beings requires the hylomorphic model, in which the brute necessity belonging to the matter is subordinated to the teleological causality of the form. The model for which I argue is pretty much Balme’s “cybernetic”. However, I explore some aspects of Aristotle’s texts that have not received much attention in the recent literature. (shrink)
