Simplicius, On Aristotle’s Categories 63.22–6

The followers of Xenocrates and Andronicus seem to include everything in what is per se and what is relative, so that according to them so great a multitude of categories is superfluous. Others divide into substance and accident; and these in a way seem to say the same as the previous people who say that accidents are relative, since they are always of other things, and that substance is per se.

Simplicius, On Aristotle’s Categories 157.18–22

Nor must one follow Andronicus who puts those items which are in relation to something after all the other categories, on the grounds that [relation] is a skhesis and a side-growth [paraphuas]. For the skhesis of the items which are in relation to something, connatural as it is, takes the lead compared with the acquired skheseis, which is also Archytas’ view. (Reinhardt 2007, 521)
