Conversations on Consciousness: What the Best Minds Think About Brain, Free Will, and What It Means to Be Human

Susan Blackmore, . . Oxford Univ., $22 (274pp) ISBN 978-0-19-517958-3

Blackmore (The Meme Machine ) began conducting interviews with leading figures in the study of consciousness for a proposed (but never realized) radio series. In book form, especially organized alphabetically, 20 transcripts with scientists and philosophers from the late Francis Crick to Daniel Dennett and Roger Penrose don't add up to a coherent presentation. The q&a format leaves Blackmore eternally circling around a handful of key issues. She's particularly fond of the philosopher's theoretical zombie, a creature that displays all the outward behavior of human consciousness but has none. She asks just about everybody if they believe it could exist, leading the exasperated Francisco Varela to blurt, "It's just a problem you create by inventing problematic situations. So what?" Other questions, like how studying consciousness affects one's conception of free will, would benefit from stronger thematic unity, a tighter narrative format like that of John Horgan's Rational Mysticism (which profiles Blackmore in her capacity as a research psychologist). These conversations are fascinating raw material, but make for a frustrating guide to a highly complex subject. 22 illus. Agent, Sheila Watson (U.K.). (Nov.)
