Abstract

This paper reviews and defends Wittgenstein’s examination of the notion of introspecting psychological states and his critique of introspectionism, in the sense of using reflective awareness as a tool for philosophical or psychological investigation. Its focus is on inner psychological states, like pains or thoughts—it provisionally excludes perceptual states from this category. It approaches the philosopher’s concept of introspection through an analysis of concepts of awareness and self-awareness. It identifies at least two different forms of self-awareness, just one of which is attention to conscious processes. It sides with those who deny that any self-awareness is perception. It outlines and evaluates the primary objections Wittgenstein made to the notion that we can find out about the nature of our mental states through introspection. These objections involve, inter alia, the privacy of psychological states and the inherent fallibility of judgments based on introspective awareness. The critique motivates more cautious and effective psychological investigation of mental states, including proper use of subjects’ introspective reports, and a conceptual approach to the philosophy of mind. Wittgenstein’s reflections prefigure much later views about the problematic nature of introspective knowledge; yet, Wittgenstein receives virtually no mention or credit for this work from contemporary writers
