SOCRATES: It is a wonderfully unified theory, and consistent, as far as I can tell. But am I really to accept that I myself - the thinking being that I call ‘I’ - has no direct knowledge of the physical world at all, but can only receieve arcane hints of it through flickers and shadows that happen to impinge on my eyes and other senses? And that what I experience as reality is never more than a waking dream, composed of conjectures originating from within myself?
