Sympathy: A Philosophical Analysis (2002)

It is widely held in contemporary moral philosophy that moral agency must be explained in terms of some more basic account of human nature. This book presents a fundamental challenge to this view. Specifically, it argues that sympathy, understood as an immediate and unthinking response to another's suffering, plays a constitutive role in our conception of what it is to be human, and specifically in that conception of human life on which anything we might call a moral life depends.
