Aristotle's Perceptual Objectivism

Objectivism about perceptible qualities like colors and sounds is the view that perceptible qualities are ontologically and conceptually independent from perception. We ordinarily think of Aristotle as an objectivist about perceptible qualities – even the arch-objectivist. Yet this consensus has long been threatened by various thorny passages, including especially De anima III.2, 425b26–426a28, which appear to suggest that Aristotle is no objectivist, but a subjectivist. I show that recent attempts to make sense of these passages by appeal to Aristotle’s three-stage distinction between first potentiality, second potentiality/first actuality, and second actuality commit Aristotle to a subjectivism that he cannot consistently endorse. I argue for an alternative that vindicates Aristotle’s objectivism.
