Science of Good and Evil

A century and a half after Darwin first proposed an “evolutionary ethics,” science has begun to tackle the roots of morality. Just as evolutionary biologists study why we are hungry (to motivate us to eat) or why sex is enjoyable (to motivate us to procreate), they are now searching for the roots of human nature.

In The Science of Good and Evil, psychologist and science historian Michael Shermer explores how humans evolved from social primates to moral primates, how and why morality motivates the human animal, and how the foundation of moral principles can be built upon empirical evidence. Along the way he explains the im-plications of statistics for fate and free will; fuzzy logic for the existence of pure good and pure evil; and ecology for the development of early moral sentiments among the first humans. As he closes the divide between science and morality, Shermer draws on stories from the Yanamamö, infamously known as the “fierce people” of the tropical rain forest, to the Aum Shinrikyo cult in Japan, to John Hinckley’s insanity defense. The Science of Good and Evil is ultimately a profound look at the moral animal, belief, and the scientific pursuit of truth.

Drawing on evolutionary psychology, Skeptic publisher and Scientific American contributor Shermer (Why People Believe Weird Things) argues that the sources of moral behavior can be traced scientifically to humanity's evolutionary origins. He contends that human morality evolved as first an individual and then a species-wide mechanism for survival. As society evolved, humans needed rules governing behavior-e.g., altruism, sympathy, reciprocity and community concern-in order to ensure survival. Shermer says that some form of the Golden Rule-"Do unto others as you would have others do unto you"-provides the foundation of morality in human societies. Out of this, he develops the principles of what he calls a "provisional ethics" that "is neither absolute nor relative," that applies to most people most of the time, while allowing for "tolerance and diversity." According to the "ask-first" principle, for instance, the performer of an act simply asks its intended receiver whether the act is right or wrong. Other principles include the "happiness" principle ("always seek happiness with someone else's happiness in mind"), the liberty principle ("always seek liberty with someone else's liberty in mind") and the moderation principle ("when innocent people die, extremism in the defense of anything is no virtue, and moderation in the protection of everything is no vice"). Shermer's provisional ethics might reflect the messy ways that human moral behavior developed, but his simplistic principles establish a utilitarian calculus that not everyone will find acceptable. 35 b&w illus.
