Aristotle, The Categories

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.
