  Most importantly, though, the point on which Italos seems to differ from Ammonius’ account of the three types of genera is that he considers not only the genera after the particulars as acquired by our mind by abstraction but also the genera in the particulars as such. For it seems that the genera after the particulars are acquired by our mind by abstraction of the common characteristics of perceptible individuals, just like in Ammonius’ commentary, while the genera in the particulars are acquired by our mind by abstraction of the particular form from the matter involved in each particular. Therefore, the genera in the particulars do seem to represent, on Italos’ view, what they represent for Proclus and Syrianus, namely immanent forms that are particular.
