If the Universe really were made for us, if there really is a benevolent, omnipotent, and omniscient God, then science has done something cruel and heartless, whose chief virtue would perhaps be a testing of our ancient faiths. But if the Universe is heedless of our aspirations and our destiny, science provides the greatest possible service by awakening us to our true circumstances. In accord with the unforgiving principle of natural selection, we are charged with our own preservation—under penalty of extinction.
And yet we go from massacre to massacre; and as our technology becomes more powerful, the magnitude of the potential tragedy grows. The many sorrows of our recent history suggest that we humans have a learning disability. We might have thought that the horrors of World War II and the Holocaust were enough to innoculate us against the toxins there revealed and unleashed. But our resistance quickly fades. A new generation gladly abandons its critical and skeptical faculties. Old slogans and hatreds are dusted off. What was only recently muttered guiltily is now offered as political axiom and agenda. There are renewed appeals to ethnocentrism, xenophobia, homophobia, racism, sexism, and territoriality. And with a sigh of relief we are apt to surrender to the will of the alpha, or long for an alpha we can surrender to.
Ten thousand generations ago, when we were divided into many small groups, these propensities may have served our species well. We can understand why they are almost reflexive, why they should be so easy to evoke, why they are the stock in trade of every demagogue and hack politician. But we cannot wait for natural selection to further mitigate these ancient primate algorithms. That would take too long. We must work with what tools we have—to understand who we are, how we got to be that way, and how to transcend our deficiencies. Then we can begin to create a society less apt to bring out the worst in us.
Still, from the perspective of the last ten thousand years extraordinary transformations have lately been playing themselves out. Consider how we humans organize ourselves. Dominance hierarchies requiring debasing submission and obedience to the alpha male, as well as hereditary alphahood, were once the global standard of human political structure, justified as right and proper and divinely ordained by our greatest philosophers and religious leaders. These institutions have now almost vanished from the Earth. Chattel slavery—likewise long defended by revered thinkers as preordained and deeply consonant with human nature—has been nearly abolished worldwide. Just a minute ago, all over the planet, with only a few exceptions, women were subordinate to men and denied equal status and power; this also was thought predetermined and inevitable. Here too, clear signs of change are now evident nearly everywhere. A common appreciation of democracy and what are called human rights is, with some backsliding, sweeping the planet.
Taken together, these dramatic societal shifts—often in ten generations or less—provide a compelling refutation of the claim that we are condemned, without hope of reprieve, to live out our lives in a barely disguised chimpanzee social order. Moreover, the shifts are occurring so swiftly that they cannot possibly be due to natural selection. Instead, our culture must be drawing forth propensities and predispositions that already reside deep within us.
We humans hold at least 99.9% of our DNA sequences in common. We are far more closely related to one another than we are to any other animal. By the similarity standards we use in other matters, humans—even of the most disparate cultures and ethnic origins—are essentially identical in our heredities. Of the immense number of possible beings, realized and unrealized, we all are cut from the same cloth, made on the same pattern, granted the same strengths and weaknesses, and will ultimately share the same fate. Given the reality of our mutual interdependence, our intelligence, and what is at stake, are we really unable to break out of behavior patterns evolved to benefit our ancestors of long ago?
