Synopsis
Book by Matt Ridley
Reviews
How do organisms whose behavior is apparently determined by
``selfish genes'' become social beings, let alone altruists and
saints? Ridley, former science editor of the Economist, looks to
the growing field of evolutionary psychology for answers.
This new discipline draws on insights from anthropology,
economics, and politics, as well as on the evolutionary trends
the author explored in The Red Queen: Sex and the Evolution of
Human Nature (1994). Other organisms besides humans have learned
to cooperate. The social insects have long been taken as models
for human society; the division of labor they exhibit is one of
the key advantages of social living. Vampire bats nest in large
groups, and it is common for a successful hunter to share its
meal with a neighbor, in hopes that the favor will be returned at
a later date. This discovery leads to a digression on the famous
``prisoner's dilemma'' of game theory; the first studies seemed
to show that the selfish player invariably wins. It now appears
that a cooperative player with a ``tit for tat'' strategy will
outlast the purely selfish one. Communal hunting raises
interesting issues, too. Surplus meat is often traded for sex
with an attractive female neighbor. Early modern humans so
effectively hunted large animals that many--the mammoth, for
example--became extinct. Another negative effect of large-scale
cooperation is war. It is evidently difficult even for highly
sophisticated social beings to abandon the notion that only their
own tribe is really human and that others must be exterminated.
The other side of the coin is trade, which depends on mutual
trust. ``Trust is as vital a form of social capital as money is a
form of actual capital,'' Ridley argues in a concluding chapter
in which he attempts to draw lessons for the modern political
arena.
A provocative look at some of the central questions about
what makes us human; strongly recommended. -- Copyright ©1997, Kirkus Associates, LP. All rights reserved.
Relying heavily on game theory, zoologist and science writer Ridley focuses on how cooperation evolved in the generally selfish world of humankind. The result is a fascinating tale incorporating studies in theoretical and evolutionary biology, ecology, economics, ethology, sociology, and anthropology. Ridley details many complex behaviors, such as altruism in animals and humans, and reviews many anthropological investigations to show how these behaviors manifest themselves in differing groups. He also develops some absorbing ideas regarding extinct civilizations. Unfortunately, his conclusions are sometimes at odds with his claim that individual property rights are the key to conservation and that environmentalists are misguided. His criticisms of conservation efforts and of the concept of the "noble savage" can be one-sided, and his sources are limited. Still, the material will captivate a wide audience, including scholars who appreciate the original literature cited. Highly recommended.?Constance A. Rinaldo, Dartmouth Coll.

Since Darwin taught us to view nature as a brutal competition among species, few philosophers have regarded virtue as a natural impulse. Yet it is to evolutionary biology, not ethical theory, that Ridley turns for an explanation of why people often sacrifice self-interest for the common good. With evidence from the latest research, he demonstrates that the hidden maneuvering of the genes punishes the egotist and rewards the saint. But don't expect the dance of the genes to follow a politically correct choreography: Ridley advances highly controversial arguments on the sexual division of labor, on the politics of environmentalism, and on the causes of war. Certainly, no one should look to these pages for a genetic formula for universal harmony and peace. But Ridley concludes with a compelling appeal for a renewal of natural communities in which our best instincts can flourish. At a time of rising fears about bioscience, Ridley still inspires hope that biology may be an ally, not a foe, in the fight for a moral world. Bryce Christensen
