 The turn of the century saw a significant increase in the amount of attention being paid by philosophers to empirical issues about moral character. Dating back at least to Plato and Aristotle in the West, and Confucius in the East, philosophers have traditionally drawn on empirical data to some extent in their theorizing about character. One of the main differences in recent years has been the source of this empirical data, namely the work of social and personality psychologists on morally relevant thought and action.
