Introspective Knowledge and Displaced Perception
"Dretske remarks that there are ‘two important differences between introspective knowledge and other forms of displaced perception’ (p. 60). What are these differences? Are they enough to call into question his view of introspective knowledge as displaced perception?"
The second chapter of Naturalizing the Mind is in the main an attempt to provide an account of introspective knowledge consistent with the Representational Thesis. Dretske takes introspective knowledge to be a given and proceeds by trying to explain how such knowledge is possible without appealing to an ‘inner sense’, an idea that seems to conflict with the Thesis’s commitment to externalism about the content of mental states. To this end, he proposes that introspection is a species of displaced perception.
However, he highlights two important differences between introspective knowledge and other forms of displaced perception that seem to suggest that introspective knowledge cannot in any relevant sense be viewed as an instance of displaced perception.
