Abstract

Gareth Evans has observed that one merely needs to ‘look outward’ to discover one’s own beliefs. This observation of what has become known as belief ‘transparency’ has formed a basis for a cluster of views on the nature of introspection. These views may be well suited to account for our introspective access to beliefs, but whether similar transparency-based accounts of our introspective access to mental states other than belief can be given is not obvious. The question of whether a transparency-based account can be generalized beyond beliefs is part of the larger issue whether introspection of different mental states can receive broadly the same account—whether introspection is unified. My aim is to examine one particularly thorough attempt at generalizing a transparency-based account of introspection due to Alex Byrne. I argue that the resulting view does not offer a unified account of introspection, even across a handful of mental states. In doing so, I highlight two difficulties most views on introspection that try to offer a unified account would have to face, even if they are not based in belief transparency. The subsequent move away from introspective unification has ramifications for several other philosophical debates, such as the architecture of the mind and our rationality
