For instance, I shall omit to speak about genera and species, as to whether they subsist in the nature of things or in mere conceptions only; whether also if subsistent, they are bodies or incorporeal, and whether they are isagkge from, or in, sensibles, 3 and subsist about these, 4 for such a treatise is most profound, and requires another more extensive investigation. Besides, it is necessary that genera should be presupposed, and when formed by specific differences, that they should consummate species, whence also genera are by nature prior.

Still, this signification appears to be most ready, 7 for they are called Heraclidae who derive their origin from the genus of Hercules, and Cecropidae who are from Cecrops; also their next of kin. The work includes the highly influential hierarchical classification of genera and species from substance in general down to individuals, known as the Tree of Porphyryand an introduction which mentions the problem of universals.

Moreover, genera exceed, from comprehending the species which are under them, but species exceed genera by their proper differences; besides, neither can species become most generic, nor genus most specific.
