En este texto argumento a favor de la consideración de la forma como sujeto y, por tanto, como responsable de la identidad del objeto a través del movimiento. Se consideran sucesivamente la prioridad de la forma como sustancia, su carácter particular y los distintos sentidos en los que algo puede ser sujeto, para concluir por qué en Z, 3, la forma es el mejor candidato no sólo para ser sustancia, sino para ser sujeto en sentido principal. El objeto del texto (...) es abordar la discusión en torno a por qué la forma satisface ontológicamente mejor que la materia o el compuesto el criterio de ser sujeto y las consecuencias filosóficas de esa postura. Como corolario, haré algunas observaciones en torno a la doble ontología que se sigue en Aristóteles desde Categorías o Metafísica. (shrink)

Aristotle states in Metaphysics Z13 that nothing said universally τῶν ϰαϑόλου λεγομένων is substance, rather the substance of each thing is particular to it. The natural interpretation of this statement is that being said universally is a sufficient condition for not being substance. But this claim is very perplexing since it is the key premiss in the following apparently inconsistent set:Form is substance.Form is universal.Nothing universal or said universally is substance, rather the substance of something is particular ἴδιος to it.

In Metaphysics Z 13 Aristotle argues that no universal can be substance. Prima facie, this appears to rule out the possibility that any universal can be substance, species as well as genera. Nevertheless, many commentators have denied that this chapter intends to rule out the possibility that any universal can be substantial. Aristotle, it is thought, cannot wish to deny that any universal can be substance because he believes that some universals are substances, viz. species.

This book investigates Aristotle’s views on abstraction and explores how he uses it. In this work, the author follows Aristotle in focusing on the scientific detail first and then approaches the metaphysical claims, and so creates a reconstructed theory that explains many puzzles of Aristotle’s thought. Understanding the details of his theory of relations and abstraction further illuminates his theory of universals. Some of the features of Aristotle’s theory of abstraction developed in this book include: abstraction is a relation; perception (...) and knowledge are types of abstraction; the objects generated by abstractions are relata which can serve as subjects in their own right, whereupon they can appear as items in other categories. The author goes on to look at how Aristotle distinguishes the concrete from the abstract paronym, how induction is a type of abstraction which typically moves from the perceived individuals to universals and how Aristotle’s metaphysical vocabulary is "relational.’ Beyond those features, this work also looks at how of universals, accidents, forms, causes and potentialities have being only as abstract aspects of individual substances. An individual substance is identical to its essence; the essence has universal features but is the singularity making the individual substance what it is. These theories are expounded within this book. One main attraction in working out the details of Aristotle’s views on abstraction lies in understanding his metaphysics of universals as abstract objects. This work reclaims past ground as the main philosophical tradition of abstraction has been ignored in recent times. It gives a modern version of the medieval doctrine of the threefold distinction of essence, made famous by the Islamic philosopher, Avicenna. (shrink)

El presente trabajo de investigación tiene por objetivo reconstruir la noción de identidad práctica tanto en Aristóteles como en Leibniz, a fin de mostrar en qué medida el hannoveriano es deudor del Estagirita y en qué medida se distingue una propuesta de la otra. Para lograr esto hacemos dos cosas: por un lado, analizamos la noción aristotélica de praxis y de agencia moral a la luz de su noción de habituación; por otro lado, damos cuenta de la dimensión práctica que (...) el hannoveriano adscribe a su noción de identidad personal, a partir de sus nociones de conscientia y cualidad moral. -/- The purpose of this research is to reconstruct the notion of practical identity in both Aristotle and Leibniz in order to show to what extent, the Hanoverian is indebted with Aristotle and to what extent one proposal can be distinguished from the other. To achieve this we do two things: on the one hand, we analyze the Aristotelian notion of praxis and moral agency trough his notion of habituation; on the other hand, we notice the practical dimension that Leibniz assigns to his notion of personal identity, based on his notions of conscientia and moral quality.

Aristotle states inMetaphysicsZ13 (1038b9-11) that nothing said universally τῶν ϰαϑόλου λεγομένων is substance (οὐαία), rather the substance of each thing is particular to it (οὐαία ἐϰάστου ὴ ίδιος ἐϰάστῳ). The natural interpretation of this statement is that being said universally is a sufficient condition for not being substance. But this claim is very perplexing since it is the key premiss in the following apparently inconsistent set:(1)Form is substance.(2)Form is universal.(3)Nothing universal or said universally is substance, rather the substance of something (...) is particular ἴδιος to it.

Some wag reported the following story: Scholars have recently established that the Iliad and the Odyssey were not, after all, written by Homer. They were actually written by another author, of the same name.The majority of current theories of naming and reference, including ones as divergent in other respects as those of Russell and Searle, would rule this story impossible. They would do so on roughly these grounds: the sense and reference of the name ‘Homer’ is determined, given the absence (...) of other reliable testimony, by the sole description: ‘Author of the Iliad and the Odyssey’. ‘Homer is the author of the Iliad and the Odyssey’ is therefore known a priori, hence necessarily true. There could not be another author of that name and claim to fame.In lectures delivered at Princeton in the Winter of 1970, Saul Kripke offered a lucid alternative to such theories. (shrink)
