 This entry provides a brief historical account of some important developments in philosophical approaches to good moral character. Approximately half the entry is on the Greek moralists Socrates, Plato, Aristotle, and the Stoics. Of these, most attention is given to Aristotle’s views, since most other philosophical discussions of character are indebted to his analysis. The latter half of the entry explores how other philosophers have responded to the concerns first raised by the Greeks. Some philosophers, such as Hugo Grotius and Immanuel Kant, represent a “modern” approach to character that subordinates it to other moral notions such as duty and obedience to law. Other philosophers, such as David Hume, Karl Marx, John Stuart Mill, and T. H. Green take an interest in the psychology of moral character that is more reminiscent of the Greeks. Finally, this entry indicates the directions taken by some contemporary philosophers in recent work on or related to moral character.
