DETERMINED MORALITY:

Darwin and the Descent of Morality (Benjamin Wiker, November 2001, First Things)

True to his naturalist bent, Darwin's natural history of morality (or more properly, moralities) assumed evolution to be true and sought to explain how the existing moral varieties could have evolved in the same way that natural selection had brought about the great variety of existing species.

For Darwin the "moral faculties of man" were not original and inherent, but evolved from "social qualities" acquired "through natural selection, aided by inherited habit." Just as life came from the nonliving, so also the moral came from the nonmoral.

From the beginning, then, Darwin rejected the Christian natural law argument, according to which human beings are moral by nature. Instead, he followed the pattern of the modern natural right reasoning of Thomas Hobbes, John Locke, and Jean-Jacques Rousseau, which assumed that human beings were naturally asocial and amoral, and only became social and moral historically. That is why Darwin called his account a natural history of morality. [...]

What we call "conscience" was also the result of natural selection. Darwin described it as a "feeling of dissatisfaction which invariably results . . . from any unsatisfied instinct." Since the "ever-enduring social instincts" were more primitive and hence stronger than instincts developed later, the social instincts were the sources of our feelings of unease when some action of ours violated them. Such feelings of unease, Darwin explained, we now call "conscience."

It might seem that Darwin's arguments for human sociability and the moral conscience could be marshaled to support a conservative moral position. Yet mere "sociality," even with a conscience grounded in evolutionary imperatives, does not at all mean that nature has created a definite moral standard, such as natural law. Quite the reverse. At bottom, everything is variable.

So both my decision to bash someone over the head and steal his food and my regret over the action are a product of natural selection? Posted by Orrin Judd at November 20, 2002 7:21 PM
