 Second, if we focus on the question of whether we are prima facie justified in accepting the contents of our intuitions, there may be a feature which distinguishes intuition from all other putative sources of evidence. Only intuition is clearly capable of epistemic self-support because it is the only source which produces non-doxastic states with epistemically normative content. Whether or not apparent perception that p, introspection that p, or apparent memory that p justify us in believing their content is, it seems, a question they cannot answer as their content is never epistemic. Hence, intuition appears distinguishable from our other putative sources of evidence in being both required for a coherent epistemology and capable of epistemic self-support. So, if any source of evidence can be defended against global skeptical attack, it seems that intuitions can.
