Abstract

Contemporary philosophers of perception, even those with otherwise widely differing beliefs, often hold that universals enter into the content of perceptual experience. This doctrine can even be seen as a trivial inference from the observation that we observe properties – ways that things are – as well as things. I argue that the inference is not trivial but can and should be resisted. Ordinary property perception does not involve awareness of universals. But there are visual experiences which do involve determinate universals: following Wittgenstein, I call these ‘aspect experiences’. The common view of perceptual content effectively conflates aspect experiences with mere property perceptions. Wittgenstein’s later writings on the philosophy of psychology provide an alternative way to think about both aspects and properties. It also forms a contrast with Wittgenstein’s own early treatment of perception in the Tractatus, the doctrine of which is much closer to the contemporary norm among philosophers of perception. In seeing how Wittgenstein moved away from his early view, we can see how we might move away from that norm.
