Abstract

This paper addresses the question of whether, according to Plato, there are forms of sensible qualities; it is also addressed to the wider question of whether there are forms of physical and material things more generally. In particular, it considers the tension raised by the following theses: (1) a Platonic form is the essence of some thing; (2) for Plato those essences that are forms are imperceptible and are knowable through reasoning alone; (3) knowing the essence of a particular color (e.g., red) requires presentation with the relevant perceptible quality and hence requires sense perception; and (4) if a sense perceptible quality has an essence, then that essence is a form. The solution I defend to this puzzle basically consists of accepting theses (1) through (3) but denying thesis (4). Sensible qualities, according to Plato, do have essences, but specifying their essences does not require that one postulate a separate form.
