My previous essay on sensory qualities indicated that past philosophies generated doubts about the validity of the senses. As would be expected, historically there have been criticisms levied against all of the standard forms of gaining knowledge: perception, as we’ve already seen, but also the conceptual faculty/faculty of reason, and the art of logic. The principle that consciousness has identity gives a general answer to these kinds of criticisms. It also highlights what should be regarded as the proper starting point for an epistemology.
