What makes us moral: Crossing boundaries of biology, by Neil Levy (oneworld, 2004)
Abstract
“Beer Gut Gene Discovered” announced the Sydney Morning Herald in 2003 (January 9)—yet another media declaration that scientists have uncovered the “gene for” such-and-such. Claims such as these are, in the popular consciousness, often conflated with proposals from sociobiologists and evolutionary psychologists regarding the innateness of certain human traits: infanticide, rape, or intelligence correlated with gender or race. When these traits are nasty or politically disconcerting (as are the three listed) then those pressing the claims are usually quick to point out that to identify any such tendency as the manifestation of an evolutionary adaptation is in no sense to exonerate the behaviour or to justify any political arrangement designed to accommodate it. Often, however, though we may not be quite able to articulate where this defence fails, we are left feeling uneasy.
