Many philosophers believe that normative ethics is in principle independent of psychology. By contrast, the authors of these essays explore the interconnections between psychology and moral theory. They investigate the psychological constraints on realizable ethical ideals and articulate the psychological assumptions behind traditional ethics. They also examine the ways in which the basic architecture of the mind, core emotions, patterns of individual development, social psychology, and the limits on human capacities for rational deliberation affect morality.Owen Flanagan is Professor of Philosophy at Duke University.
