Team Egoism

First, you should read some of the section on Morality and Self-Interest (beginning on page 31o) in our Vice and Virtue textbook. Some specific articles worth reading: Rachels's "Egoism and Moral Skepticism" (pages 332-342), Pojman's "Egoism, Self-Interest, and Altruism" (345-349), Rand's "The Virtue of Selfishness" (342-345), and Browne's "The Unselfishness Trap" (327-332).
