p.206 We can think of introspection... as a self-dialogue, and its role in the acquisition of self-knowledge, I believe, can hardly be exaggerated. That it plays such a role is a consequence of a human characteristic that deserves to be judged remarkable. This is the susceptibility of our mind/body complexes to respond to the questions that we put to ourselves, to create special states of consciousness through merely raising a question. It is only slightly less remarkable that these states provoked into existence by our questions about ourselves quite often supply the materials for accurate answers to those same questions.
