What about morality? Do you approach questions of morality with ambivalence, finding it easy to justify your own or others’ behavior with a reference to “survival of the fittest”? People sometimes say that we lack remorse or guilt like it’s a bad thing. They are sure that remorse and guilt are necessary to being a “good” person. But there is probably no universal, and certainly no objective, morality. Despite millennia of arguments among theologians and philosophers, no one can really agree on the contours and parameters of morality. From where I stand, it’s hard to put such faith in something so wildly elastic and changeable, something associated with horrors as diverse as honor killings, “just” wars, and capital punishment. Like many people, I adhere to a religion that gives me moral guidance. The practice of it is just good sense—it keeps you out of prison and safely hidden in the crowd. But the heart of morality is something I have never understood.
