“The idea of consciousness as a “show” is ultimately derived from the bankrupt representational theory of the mind – a notion that things are present to us by virtue of being “represented” or “modelled” in the brain. You cannot get to representation, however, without prior (conscious, first-order) presentation, so the latter cannot explain the former. Neuroscientists of consciousness try to elude this obvious objection by asserting that representations are not (necessarily) conscious. In fact, all sorts of aspects of consciousness are not conscious after all.
According to Nicholas Humphrey, “before consciousness ever arose, animals were engaged in some kind of inner monitoring of their own responses to sensory stimulation”. What is “inner” about unconscious processes, material events in the material brain? And how can they amount to monitoring? These questions are not silenced by the author’s reassurance that consciousness is “the product of some kind of illusion chamber, a charade”. Nor does Humphrey tell us how he awoke from his consciousness to discover that it is an illusion.”
