The Content Skeptic argues that a subject could not have introspective know
ledge of a thought whose content is individuated widely. This claim is inco
rrect, relying on the tacit assumption that introspective knowledge differs
significantly from other species of knowledge. The paper proposes a reliab
ilist model for understanding introspective knowledge according to which in
trospective knowledge is simply another species of knowledge, and according
to which claims to introspective knowledge are not, as suggested by the Co
ntent Skeptic, defeated by the mere possibility of error. This way of under
standing introspective knowledge affords a robust theory of privileged acce
ss consistent with semantic externalism.
