It Ain't Necessarily So: The Dream of the Human Genome and Other Illusions

It Ain't Necessarily So is a collection of some of his more characteristic reviews from the 1980s and 1990s. The Mismeasure of Man, by Stephen Jay Gould; Unto Others: The Evolution and Psychology of Unselfish Behavior, by Elliott Sober and David Sloan Wilson; sociological studies of Sex in America; and Ruth Hubbard's books on gender in science: all his essays are informative yet lively, with a high acid content--as when he begins his piece on the Human Genome Project with a definition of "fetish."

Lewontin's prose is worth reading in itself, but what lifts this anthology to another level is that it also includes replies and rebuttals selected from the New York Review's letters column--a forum that doubles as the intellectual's World Wrestling Federation. For the older pieces, he also includes updates, "where are they now" summaries to give a sense of historical change in each field. Assertive, brilliant, sarcastic, dense, wide-ranging--Lewontin may be challenging, but he is never dull. --Mary Ellen Curtin

"Scientists, by their practices, seem to place little importance on the actual composition of their communication. For example they never read their papers aloud when they give talks about their work, but speak ex tempore. For other intellectuals the words are the matter but scientists think of themselves as simply objectively reporting the facts of nature. Like the Delphic Oracle they sit perched on their tripods, with upturned eyeballs, and out of their mouths' issue nature's words (p.189)"

I do not know where Lewontin, a scientist himself, has encountered these caricatures. My own experience after working in the sciences for 9 years suggests that scientists, just like the rest of us, are not paradigm cases but individuals. So if Lewontin has specific complaints about specific scientists he should listen to his own advice that "words are the matter" and phrase his criticism appropriately. Otherwise he may want to remember that above and away from the shrine of Delphi is a grove that is difficult to reach, at the end of an ancient cobblestone trail called the Kalki Skala, or "evil stairway." Nearby are two pinnacles from which those convicted of sacrilege against the gods were thrown to their deaths.

This book deals much more with the philosophical implications authors imply in their texts than the actual Science, but has enough Science to placate those looking for basic information on genetics, etc. Lewontin's humble and witty approach is welcoming, and his thought process is enjoyable. His 'tell it like it is' approach to issues like Social Darwinism and the Human Genome Project are worth reading, especially for people relegated outside the physical and natural sciences who may be unaware of these perspectives. (Especially those who infrequently read Science texts and are consequently doomed to linger in outdated material).

The key strength of this text lies in its challenging other arguments, which is often stronger than texts with centralized theses. Because of Lewontin's critical authority, he is freer from the ideological rampages that blind many of the authors he addresses. My favorite sections of the text were the 'exchanges,' where authors wrote in to the magazine criticizing Lewontin and he responds. For the reviewer here who rebuked Lewontin for his simple approach to complex problems or his philosophical leaning, note that often those letters he responds to are written by the authors of the books he derides. If he has missed 'the point' that they were forwarding, it is addressed there, and if he has not and you see other discrepancies than you've one upped the authors and should look for more sophisticated arguments anyway. After all, if you can't adequately defend your own work against 'paltry' arguments, how strong is it in the first place?

This text's subject matter is broad and marvelously entertaining. Read up!

The only consistent theme in this compilation is that of the iconoclast. Chipping away at perceived flaws in other people is a Lewontin specialty. He has favoured targets, such as Richard Dawkins and Philip Rushton, are frequently mentioned. A glaring omission, particularly in the updating Epilogue to "Darwin's Revolution", is that of Daniel C. Dennett's DARWIN'S DANGEROUS IDEA. Given Dennett's scathing critique of The Spandrels of San Marco, co-authored by Lewontin and Stephen Gould, the oversight surprises.

The most engaging sections of the book are essays on the Human Genome Project, genetics and cloning. In an effort to undercut scientists like E.O. Wilson or Richard Dawkins, Lewontin attempts to restrict DNA's role to 'the stupid molecule' it was once considered. Using every verbal trick available, he writes a lawyer's brief against the Project and its supporters. Stripping away nearly every function DNA performs and removing it from its environment, he leaves the reader wondering if 'the stupid molecule' is worth the funding. Like many others, Lewontin knows The Human Genome Project isn't a scientific enterprise, but a business one. He's correct in that assessment, but his hidden agenda remains shrouded. Lewontin is terrified that once the genome has been mapped and better understood, this Agassiz Research Professor will discover that human beings aren't the divinely placed species he and many others would like us to be. Because he can think about so many esoteric subjects and salamanders can't [or at least can't express those thoughts], it follows that we're elevated above the other animals instead of simply different. Lewontin is a tenured human and demotion holds no appeal. He's not alone in that, which is why his books sell.

The book needs an index. There are simply too many topics and names running through this collection for either Lewontin nor The New York Review to be excused for this lack. In a time of electronic word processing the omission is unforgivable. A bibliography of recommended readings would also be a benefit. If he took the trouble to update his opinions, he could have helped the reader along with supporting information. Not an approach one would admire in an academic.
