  Even if this much is granted—and to repeat, much of what has just been said is unavoidably controversial—many questions remain. For example, is form best understood as universal or particular?  However that issue is to be resolved, what is the relation of form to the compound and to matter?  If form is substance, then what is the fate of these other two candidates?  Are they also substances, if to a lesser degree?  It seems odd to conclude that they are nothing at all, or that the compound in particular is nothing in actuality; yet it is difficult to contend that they might belong to some category other than substance.
