I. In analytic philosophy, so-called 'univocalism' is the prevailing interpretation of the meaning of terms such as 'being' or 'existence', i.e. the thesis that these terms have only one meaning (see Russell, White, Quine, van Inwagen). But some analytical philosophers, inspired by Aristotle, maintain that 'being' has many senses (Austin, Ryle). II. Aristotle develops an argument in favour of this last thesis, observing that 'being' and 'one' cannot be a single genus, because they are predicated of their differences (Metaph. B (...) 3). III. But 'being' for Aristotle has also a unity, i.e. 'focal meaning', which coincides with substance (Metaph. Γ 2), and substance has not only an ontological priority, but also a logical priority, in respect to the other beings, as was shown by G. E. L. Owen. IV. This 'focal meaning' cannot be identified with primary substance, i.e. with the unmovable mover, as some interpreters pretend, because this latter has only an ontological, not a logical, priority in respect to the world. V. The impossibility of this interpretation results from Aristotle's rejection of an essence and a substance of being (Metaph. B 4), i.e. the rejection of what the Christian philosophers called esse ipsum subsistens. (shrink)

In his recent edition, with translation and commentary, of Aristotle, Eth. Nic. VI, Hans-Georg Gadamer reproposes his interpretation of Aristotle's practical philosophy as a model for his own hermeneutics, confirming in this way his tendency to identify practical philosophy with the intellectual virtue of phronesis. Furthermore, although he recognizes the primacy attributed by Aristotle to the theoretical life, Gadamer tends to undervalue it and to consider phronesis and sophia at the same level. In particular he believes that the theoretical life (...) was for Aristotle an ideal accessible only to the gods. Unlike Heidegger, who refuses Aristotle's position because of the primacy of theoretical life, but appropriates his practical philosophy, Gadamer thinks that today is still possible to follow Aristotle, but only if we reduce that primacy. The article shows how, according to Gadamer, what Aristotle says about theoretical life, if rightly understood, can still be accepted. /// Na sua edição recente, com tradução e comentário ao Livro VI da Ética a Nicómaco de Aristóteles, Hans-Georg Gadamer reaflrma a sua interpretação dafllosofia prática de Aristóteles como modelo para a sua hermenêutica, confirmando deste modo a sua tendência a identificar a filosofia pratica de Aristóteles com a virtude dianoética da phronesis. Além disso, e apesar de reconhecer o primado atribuido por Aristóteles à vida teorética, Gadamer tende a desvalorizá-lo e a considerar a phronesis e a sophia como estando no mesmo piano. Gadamer parece especialmente convencido de que a vida teoretica para Aristóteles constitui um ideal apenas acessivel aos deuses. Ao contrário de Heidegger, que refuta a posição de Aristóteles por causa do primado atribuido à vida teorética, mas se apropria da sua filosqfia prática, Gadamer pensa ser ainda possivel seguir Aristóteles, para o efeito apenas se exigindo uma redimensionação desse primado. Enfim, o artigo demonstra como, segundo Gadamer, aquilo que Aristoteles diz acerca da vida teorética pode, se correctamente entendido, ser aceite ainda hoje. (shrink)

I discuss Enrico Berti “Saggezza o filosofia pratica?” published in the current issue of “Ethics & Politics”. I argue that Kant’s normative ethics was in fact a kind of virtue ethics and most of the opposition between Aristotelianism and Kantian ethics in the last three decades has been basically an exercise in cross-purpose.

Comparaison entre la philosophie pratique aristotélisante d'aujourd'hui, représentée en Allemagne surtout par H.G. Gadamer, J. Ritter et leurs élèves, et les théories d'Aristote sur la phronesis et l'ethos, visant à montrer que ces dernières, dans la pensée du Stagirite, ne remplissent pas, contrairement à ce que croient ces interprètes, le rôle de la philosophie pratique toute entière. Contrast between the aristotelizing practical philosophy of today, represented in Germany especially by H.G. Gadamer, J. Ritter and their followers, and Aristotle's theories on (...) phronesis and ethos, in order to show that these theories, in the Stagirite's thought, don't play, against the opinion of those interpreters, the rôle of the whole practical philosophy.

La classificazione delle scienze di Pietro d'Abano costituisce un'interessante riformulazione della classificazione analoga, proposta da Aristotele in Metaph. VI, e della teoria degli abiti dianoetici, proposta da Aristotele in Eth. Nic. VI. Come risulta dal Conciliator per quanto concerne la medicina e dal Lucidator per quanto concerne l'astronomia, Pietro segue la classificazione aristotelica e le interpretazioni che di essa erano state date nel medioevo , aggiungendovi come contributo originale l'introduzione di una parte pratica sia nella medicina che nell'astronomia , dove (...) quest'ultima deriva da Tolomeo e dagli Arabi. Peter of Abano's classification of the sciences is an interesting reformulation of the analogous classification proposed by Aristotle in Metaphysics VI, and of Aristotle's theory of the dianoetic habits found in Nichomachean Ethics VI. As apparent in the Conciliator for medicine and in the Lucidator for astronomy, Peter follows the Aristotelian classification and the interpretations of it given in Middle Ages , adding as his own original contribution the introduction of a practical part on medicine and on astronomy , the latter derived from Ptolemy and the Arabs.

In order to explain the contemporary relevance of Aristotle’s thought, the following discussion explores various examples of Aristotelian theories, concepts, and distinctions which remain at the centre of the philosophical debate. From the domain of logic we consider the notion of category, which was developed by G. Ryle, the distinction between apophantic and semantic discourse, that was stressed by J. Austin, the debate on the principle of non- contradiction, and the theory of fallacies; from the domain of physics, we examine (...) the concepts of substrate, form, continuum, and time, which have been discussed by I. Prigogine and R. Thom; from the field of biology, we consider the function of form in animal generation, which M. Delbrück has compared to the role of DNA; from the field of psychology, we look at the notion of soul as a complex of dispositions, which has been identified by many philosophers as a solution of the “Mind-Body Problem;” from the realm of ethics, we investigate the distinction between action and production, an approach developed by H. Arendt, and the virtue of phronesis, which has been developed by H. G. Gadamer and A. McIntyre. In particular, we discuss the Aristotelian theory of the ambiguity of the concept of being, the notion of “focal meaning,” that has been developed by G. E. L. Owen, and the function of form in the identification of individuals, which has been pursued by M. Frede. (shrink)

A literatura crítica sobre Aristóteles ainda discute se a forma é universal ou individual. A doutrina do livro Lambda da Metafísica afirma que as causas dos indivíduos são individuais, mas é no De generatione animalium que essa doutrina é justificada: o sêmen paterno transmite ao mênstruo uma série de movimentos que determinam a alma do feto e o seu desenvolvimento corporal. Portanto, o pai é causa motora do filho e produz sua alma, que pode ser individual.

This paper aims to show that an examination of some passages in Aristotle’s work can contribute to the resolution of crucial problems related to the interpretation of ancient geometrical analysis. In this context, we will focus in particular on the famous passage of the Posterior Analytics in which Aristotle cryptically refers to the analysis practised by the geometers and we will show the fundamental importance of this passage for a correct understanding of ancient geometrical analysis.
