Los predicables de los "Tópicos" y los predicables de la "Isagoge"

Abstract

Aristotle, as well, places the species in the position of predicate, but he does so in Metaphysics Z4, in a search that, beyond the seizing of the quiddity, attains in Z17 the substance as cause through the form of its model of being: in itself, separate and one. Failing to recognise this approach, the substitution by Porphyre of the species and the difference for the definition, reinforce this misreading for centuries, thus impeding the passage, with Met. H, from what completes the definition: the difference, to what, be-yond the form, constitutes the first completion of the substance: its act of being.
