Abstract
Contemporary moral philosophers entertain theories about human nature, explore the nature of value, discuss competing accounts of the best ways to live, ponder the connections between ethics and human psychology, and discuss practical ethical quandaries. Broadly conceived, these are the same issues ancient philosophers discussed. However, the precise questions contemporary philosophers ask, the distinctions we make, the methods we employ, and the knowledge of the world and of human psychology we use in framing and evaluating ethical theories, often only faintly resemble those of our philosophical predecessors.
