Choices, efforts, intentions, and reasoning influence our behavior — but they are themselves part of a chain of causes that precede conscious awareness and over which we exert no ultimate control.

I must take a first step, or a last one, for reasons that are bound to remain inscrutable.

On almost every page, the Koran instructs observant Muslims to despise nonbelievers.

The men and women on death row have some combination of bad genes, bad parents, bad environments, and bad ideas (and the innocent, of course, have supremely bad luck). Which of these quantities, exactly, were they responsible for?

Our system of justice should reflect an understanding that any of us could have been dealt a very different hand in life. In fact, it seems immoral not to recognize just how much luck is involved in morality itself.

To see how fully our moral intuitions must shift, consider what would happen if we discovered a cure for human evil. Imagine that every relevant change in the human brain could now be made cheaply, painlessly, and safely. In fact, the cure could be put directly into the food supply, like vitamin D. Evil would become nothing more than a nutritional deficiency.
