What is morality, anyway? What are the big debates in the field of moral psychology?

Where does concern for others come from? How is it related to empathy—and is more empathy necessarily a good thing? And what can we learn from the study of those who seemingly lack normal moral feelings, such as violent psychopaths?

Here, we ask about which aspects of morality are universal. We discuss evolution, cross-cultural research, and the fascinating new science of the moral life of babies.

How does culture influence our moral thought and moral action? What role does religion play? Why are some of us conservative and others liberal, and how do political differences influence our sense of right and wrong?

Our moral feelings are usually most powerful towards our kin (such as our parents and our children) and our friends and allies. We will discuss these special bonds, and then turn to the morality of racial and ethnic bias. Then we use the tools of behavioral economics to explore the controversial question of whether we are ever truly altruistic to strangers.

We’ll discuss some clever studies that show how our moral behavior is powerfully influenced—often at the unconscious level—by the situations that we find ourselves in. Such findings raise some hard problems about determinism, free will, and moral responsibility. Most of all, if our actions are determined by our brains, our genes, and our situations, in what sense can we be said to be moral agents? The course will end by trying to address this question.
