The account of introspective certainty given in the last chapter is the first step in a theory of consciousness or awareness. The infallible reporter in the mind has evaporated, to be replaced at a different level of explanation by the notion of a speech-producing system which is invulnerable to reportorial errors just because it does not ascertain and does not report. This is just a first step, however, for there are more aspects of consciousness than just perceptual consciousness, and more things we do with speech than just make sincere reports of our experience.
