Ayn Rand's posthumously published Philosophy: Who Needs It? The selections present Rand's Objectivist philosophy, emphasizing the importance of reason, self-interest, and the rejection of altruism. Rand critiques various philosophical schools of thought, particularly Kantianism, for their undermining of reason and their promotion of irrationality and collectivism. The excerpts further explore the practical consequences of these philosophies, illustrating how flawed ideologies lead to societal decay and individual unhappiness. Finally, Rand argues for the necessity of a rational, self-interested morality as a means of individual and societal flourishing.
