In this paper, I will argue, contra Prinz, that empathy is a crucial component of our moral lives. In particular, I argue that empathy is sometimes epistemologically necessary for identifying the right action; that empathy is sometimes psychologically necessary for motivating the agent to perform the right action; and that empathy is sometimes necessary for the agent to be most morally praiseworthy for an action.
I begin by explaining what I take empathy to be. I then discuss some alleged problems for empathy and explain why some argue that empathy is unnecessary and sometimes even problematic in the moral domain. Next, I criticize a prominent alternative to an empathy-based morality. Finally, I argue that that empathy is sometimes epistemologically and psychologically necessary for doing the right thing and is sometimes necessary for moral worth. I conclude with a discussion of the important role of empathy in our everyday lives
