CONVERGENCE

The journalist and polymath delivers a delightful exploration of “the deepest idea in the universe.”

Intellectual historian Watson loves big ideas and long books, and publishers keep publishing them and buyers buying them because they’re great reading—no exception here. After 600 pages of The Great Divide: Nature and Human Nature in the Old World and the New (2012), his new book takes on the history of scientific pursuits in just under 500 pages. Passing lightly over its history before the 19th century, the author maintains that discoveries of the conservation of energy and Darwinian evolution in the 1850s began a great convergence where the sheer mass of scientific knowledge has begun “to invade other areas, other systems of knowledge traditionally different from or even opposed to science, and is starting to explain—and advance—them. Science is…bringing order to philosophy, to morality, to history, to culture in general, and even to politics.” The “soft” sciences—i.e., psychology, economics, sociology—are growing “hard.” Ethologists studying animals have quantified the devastating effects of defective parental care, and child psychologists, formerly dependent on Freud, have taken note. Today, physicists advise investors, and historians and politicians ignore science at their peril—but do it anyway. The origin of life itself has moved from a hypothesis featuring implausible chemical reactions in ancient pools to a matter of convergence. Watson argues that life, as well as consciousness, culture, even morality, may be inevitable under certain conditions. Accepted in the scientific community, convergence remains controversial among philosophers, literary critics, and some sociologists who claim that scientific knowledge is overrated, culturally determined, and only one of many ways to describe reality.

Those who reject the idea of convergence outright may not get far in this book, but readers with no objection to a sweeping, entirely fascinating history of science during the last 200 years will find an abundance of enlightening material.
