After being shown proudly around the campus of a prestigious American university built in gothic style, Bertrand Russell is said to have exclaimed, “Remarkable. As near Oxford as monkeys can make.” Much earlier, Immanuel Kant had expressed a less ironic amazement, “Two things fill the mind with ever new and increasing admiration and awe … the starry heavens above and the moral law within.” Today many who look at morality through a Darwinian lens can’t help but find a charming naïveté in Kant’s thought. “Yes, remarkable. As near morality as monkeys can make.”
So the question is, just how near is that? Optimistic Darwinians believe, near enough to be morality. But skeptical Darwinians won’t buy it. The great show we humans make of respect for moral principle they see as a civilized camouflage for an underlying, evolved psychology of a quite different kind.
This skepticism is not, however, your great-grandfather’s Social Darwinism, which saw all creatures great and small as pitted against one another in a life or death struggle to survive and reproduce — “survival of the fittest.” We now know that such a picture seriously misrepresents both Darwin and the actual process of natural selection. Individuals come and go, but genes can persist for 1000 generations or more. Individual plants and animals are the perishable vehicles that genetic material uses to make its way into the next generation (“A chicken is an egg’s way of making another egg”). From this perspective, relatives, who share genes, are to that extent not really in evolutionary competition; no matter which one survives, the shared genes triumph. Such “inclusive fitness” predicts the survival, not of selfish individuals, but of “selfish” genes, which tend in the normal range of environments to give rise to individuals whose behavior tends to propel those genes into future.
A place is thus made within Darwinian thought for such familiar phenomena as family members sacrificing for one another — helping when there is no prospect of payback, or being willing to risk life and limb to protect one’s people or avenge harms done to them.
