Although there are a very few occasions on which Aristotle speaks of words, on the one hand, or mental concepts, on the other, as universals, he was no nominalist and no conceptualist. This negative thesis I have argued sufficiently, at least to my own satisfaction, in an earlier paper. He was, rather, a realist, but of a very tenuous sort. As I said in the earlier paper, he viewed universals as real entities but lacking numerical oneness; each is numerically many, (...) and yet each is also one in some sense. The specific identity of numerically distinct particulars creates something like a class, and this is the universal.This interpretation was not, in the earlier paper, defended against those who would attribute to Aristotle a much more robust form of realism, and it is that defense which this paper will undertake to provide. The evidence which can be marshalled for the more robust realism is impressive – more so, I would say, than that which can be brought forth for either the nominalist or the conceptualist interpretations. It rests on numerous passages which either explicitly or implicitly seem to tie together as identical, forms, substances, universals, and intelligible objects. (shrink)

Saul Kripke ha presentado un conjunto de tesis esencialistas enmarcadas bajo la etiqueta«esencialismo aristotélico», esto es, la tesis que defiende la significatividad de la distinción entrepropiedades necesarias y accidentales de los objetos. Sin embargo, ¿es el «esencialismo aristotélico»acorde con el aristotelismo? Más aún, ¿puede alguna de las propiedades esenciales presentadas por Kripkeser interpretadas desde una perspectiva aristotélica? En este artículo pretendemos fundamentalmentedos cosas: 1) criticar la etiqueta «esencialismo aristotélico» a través de una hipótesis plausible acercade su elaboración; y 2) aportar (...) una explicación de las intuiciones que sustentan la metafísica kripkeanadesde la metafísica aristotélica, centrada en el paralelismo existente entre la necesidad del origenmaterial de los artefactos y la doctrina de la necesidad hipotética de la causa material desarrollada porel filósofo de Estagira.
