Wetware A computer in every living cell

This book's premise is that systems of proteins can convey and process information at the level of a single free-living cell. These proteins act as switches or transistors, functioning as the nervous system does for multicellular organisms. Bray (emer., Univ. of Cambridge, UK; Cell Movements, CH, Nov'92, 30-1490) presents abundant evidence that this is true. He uses several well-studied examples (e.g., bacterial chemotaxis) to illustrate that complex behaviors and even the appearance of "consciousness" can be the product of relatively simple combinations of switches and outcomes. Bray brings the full force of his experience and intellect to this work, showing the way toward a deeper understanding of single-cell behavior, neural net capabilities, and the innate ability to infer consciousness or agency in systems that actually have a very simple network of switches and outcomes. Complete appreciation of Wetware will require a significant biological background; some is supplied by the author while other concepts are assumed. His perspective takes readers another step away from the mind/body Descartian dualism that seems to be making a comeback among anti-intellectual and antiscientific proponents of theological arguments such as intelligent design. The arguments thus have not only scientific ramifications, but cultural and philosophical ramifications as well. Summing Up: Highly recommended. All academic, professional, and general readers. D. A.
