At least part of the schism between Republicans and Democrats is based in differing conceptions of the role of the individual. We find these differences expressed in the frequent heated arguments about crucial issues like health care and immigration. In a broad sense, Democrats, particularly the more liberal among them, are more likely to embrace the communal nature of individual lives and to strive for policies that emphasize that understanding. Republicans, especially libertarians and Tea Party members on the ideological fringe, however, often trace their ideas about freedom and liberty back to Enlightenment thinkers of the 17th and 18th centuries, who argued that the individual is the true measure of human value, and each of us is naturally entitled to act in our own best interests free of interference by others. Self-described libertarians generally also pride themselves on their high valuation of logic and reasoning over emotion.
Philosophers from Aristotle to Hegel have emphasized that human beings are essentially social creatures, that the idea of an isolated individual is a misleading abstraction. So it is not just ironic but instructive that modern evolutionary research, anthropology, cognitive psychology and neuroscience have come down on the side of the philosophers who have argued that the basic unit of human social life is not and never has been the selfish, self-serving individual. Contrary to libertarian and Tea Party rhetoric, evolution has made us a powerfully social species, so much so that the essential precondition of human survival is and always has been the individual plus his or her relationships with others.
This conclusion is unlikely to startle anyone who is at all religious or spiritual. When I was a boy I was taught that the Old Testament is about our relationship with God and the New Testament is about our responsibilities to one another. I now know this division of biblical wisdom is too simple. I have also learned that in the eyes of many conservative Americans today, religion and evolution do not mix. You either accept what the Bible tells us or what Charles Darwin wrote, but not both. The irony here is that when it comes to our responsibilities to one another as human beings, religion and evolution nowadays are not necessarily on opposite sides of the fence.
