THE BRAIN IS A MYSTERIOUS, EXCITING FRONTIER IN SCIENCE. Eminent neuroscientists have ended their careers to examine the mind-brain problem because their practice showed the speculative approach is flawed. Answers in this field will create a new weltanschauung. Long ago, Francis Bacon ushered in a revision of Aristotelian science and a new empiricist worldview. Now, the renowned Wilder Penfield's dictum "There is a switchboard operator as well as a switchboard." demands a radical rethinking in neuroscience and in our general worldview. Verschuuren's exciting interdisciplinary scrutiny is for scientists and the general reader. He does not shy from complexities such as intentionality, self-reference, and free will; and he succeeds in putting it all in ordinary language.
