Resumen de Los predicables de los "Tópicos" y los predicables de la "Isagoge"
Aristotle, as well, places che species in che position of predícate, but he does so in Metaphysics Z4, in a search that, beyond the seizing of che quiddity, attains in Z 17 the substance as cause through the form of its model of being: in itself, separate and one. Failing to recognise chis approach, che substitution by Porphyre of the species and the difference for the definition, reinforce this misreading for centuries, thus impedíng the passage, wíth Met. H, from what completes the definition: the difference, to what, beyond che form, constitutes che first completion of the substance: its act of being.
