This lecture discusses the ancient Greek philosopher Aristotle' work, the Categories, focusing on his discussion in chapter 5 of the relationship between substances and contraries. Substances - whether primary or secondary - do not have contraries themselves, and do not admit of degrees. Substances do, however, admit of or accept contraries - and this is something distinctive to substances as opposed to other things.

This lecture discusses the ancient Greek philosopher Aristotle' work, the Categories, focusing on his distinction in chapter 1 between three types of terms - Univocal (sunonuma), Equivocal (homonuma), and Derivative (paronuma). This distinction concerns the connection between linguistic expressions and meanings. Univocal terms have the same meaning, or in Aristotle's terms, "statement of essence" (logos tes ousias). Equivocal terms have the same name or expression, but different statements of essence. Derivative terms are grammatically related to each other, and have connected meanings.
