Dawkins takes to heart his title of Charles Simonyi Professor of Public Understanding of Science at Oxford in this thoughtful exegesis on the nature of science and why its detractors are all wrong. More with pity than anger, he takes Keats to task for faulting “cold philosophy” for unweaving the rainbow in the long poem “Lamia.” On the contrary, Dawkins observes, Newton’s use of a prism to split white light into the spectrum not only led to our understanding of how rainbows form in raindrops, but enabled astronomers to read the make-up of stars. Dawkins devotes a few chapters to debunking astrology, magic, and clairvoyance, arguing that, as rational adults, we need to be critical about ideas. This notion serves him handily in chapters on coincidence: He explains the exacting calculations of probabilities to show that coincidences aren—t so unusual. Yet people have a penchant for finding patterns where there are none, which leads Dawkins also to address superstitions, the class of errors known as false positives and false negatives, and a wealth of cultural practices from rain dances to human sacrifice. He takes to task what he calls bad poetic science, in which he includes the theories of his rival Stephen Jay Gould in relation to what Gould sees as the three perennial questions in paleontology: Does time have a directional arrow? Do internal or external forces drive evolution? And does evolution occur gradually or in jumps? The spleen’s so heavy here that one can anticipate a debate, if not a duel. Final chapters provide him with a platform for reweaving the rainbow, enlarging on his earlier themes and metaphors in relation to memes, genes, and evolution. The speculative writing here is less rooted in complex gene analysis than in philosophy of the Dennett school. A sharp mind is much in evidence, delighting in exposing fraud, providing instruction, baiting a colleague, and indulging in his own high-wire acts of evolutionary dreaming.

An informal, first-person account of the discovery of a genetic link to male homosexuality by a scientist who has given thought to the ramifications of his findings. With the help of Scripps-Howard journalist Copeland, Hamer, a molecular geneticist who heads the National Cancer Institute's section on gene structure and regulation, describes in just the right amount of detail how he put together his research project on homosexuality. He relates how he obtained approval, funding, a research team, and a place to work; how he found the volunteers he needed (gay brothers willing to give blood samples and answer a lot of very personal questions); and what he learned from them and their family trees. Genetics being a statistical science, there's a fair amount of discussion of statistical techniques, but happily this is mostly presented with the general reader in mind. Hamer's account offers a glimpse into both the collegiality and the politics of science, and there's a delightful chapter on a confrontation he had at Harvard with critics of his research. The final portion of his book presents theories about how genes may influence sexual behavior and other human attributes and speculation about the implication of his research. In July 1993, in the midst of intense public debate over gays in the military, the journal Science published Hamer's paper, ``A Linkage Between DNA Markers on the X Chromosome and Male Sexual Orientation.'' Tabloids and TV talk shows took it from there. Hamer does not dwell on his time in the spotlight, but the experience evidently sharpened his awareness of public concerns and misconceptions. After noting the possible misuses of genetic research, Hamer concludes that the real danger lies in not studying sex at all. Appendixes include the Science article (not seen) and the interview questionnaire used with research participants. Nothing to titillate, but plenty to think about.

Leading neuroscientist Montague takes a biomechanical approach to explain the mental processes that occur in decision-making.
Like computers, the human brain processes data and produces a result—but with a twist, declares the author. The gray area of computational neuroscience lies in the value judgments that occur in biological systems. Nature, Montague posits in his debut, has equipped the biological machine with the added ability to determine the significance of a computation. Moreover, by storing these valuations as a byproduct of computation, the mind adapts and becomes increasingly more efficient. Repeated exposure to a typical risk-reward scenario, for example, causes the mind to anticipate outcomes. Montague revisits many of the old “right-brain” scenarios with a “left-brain” approach. With a graduate student, he replicated the famous “Pepsi Challenge” and found no relationship between the drink selected in the test and the drinks that subjects actually purchased in the stores. Though Montague’s research is thorough, his explanations vary from wry to impenetrably abstract, and the definition of value remains elusive. Value may be a burst of dopamine, a goal created from a pattern of inputs from the environment, an abstract emotion such as trust, or anything in-between. The essence of Montague’s work is that biological machines assign a value “tag” to each piece of data that they process. Whether tiny bacteria or human being, this is what differentiates us from the machines we create. The “soul” of the human machine may be the sum of these value tags. The answer to the titular question is itself a value judgment based on individual experience.
