This paper analyzes James Rachels's philosophical essay "Egoism and Moral Skepticism," tracing its central arguments back to Plato's myth of the Ring of Gyges and Glaucon's claim that humans act virtuously only out of fear of reprisal. The paper examines Rachels's critique of two related positions: psychological egoism, the descriptive claim that all human action is ultimately self-interested, and ethical egoism, the normative claim that self-interest is always morally justified. The analysis explains how Rachels dismantles both views, focusing on the logical sleight-of-hand that conflates self-interest with selfishness and the definitional maneuver that renders altruism conceptually impossible.
James Rachels's paper Egoism and Moral Skepticism begins by tracing its subject back to Plato's philosophical discussion of the myth of the Ring of Gyges. In that myth, Gyges gains the power of invisibility through a magic ring and uses it to seduce a queen, kill a king, and seize the throne. In Plato's dialogue, the character of Glaucon argues that both a virtuous man and a rogue would be unable to resist such temptation: freed from fear of reprisal, human behavior would quickly turn criminal.
Rachels traces back to Glaucon's argument two persistent philosophical positions, both of which he considers to be in error. The first he terms Psychological Egoism: the belief that human beings act only from self-interest, and that even supposed altruism is purely to the advantage of the person performing the act. Alongside this, Rachels presents the related position of Ethical Egoism: not a claim about the nature of the human mind, but a normative ethical view about how people ought to act — a quasi-philosophical view that selfishness is wholly justifiable, always and everywhere. Before arguing why both positions are in error, Rachels notes wryly that if either view were actually correct, then "the majority of mankind is grossly deceived about what is, or ought to be, the case, where morals are concerned."
Rachels considers psychological egoism to be refuted on a daily basis — altruism happens all the time, and examples abound. He offers two possible objections that could be raised on behalf of psychological egoism in the face of these facts. The first is the claim that both the selfish person and the altruist are merely expressing their own volition: each is doing what they want, must want what they are doing, and is thus gratifying a desire rather than acting unselfishly.
Rachels considers this argument so poor as to be beneath serious consideration, were it not for the fact that many people appear persuaded by its glib sophistry. The difference between selfish and unselfish action, he takes pains to point out, can be discerned — at least partially — in the sense of moral obligation that accompanies many acts in which a person is clearly not acting out of personal gratification, whether for reasons of social conformism or simply to keep a promise. He also notes that psychological egoism handles the concept of unselfishness primarily by defining it out of existence: if volition and desire are treated as gratified in whatever a person does, then the entire concept of unselfishness is rendered nonsensical — yet most of us perceive unselfishness as intrinsically intelligible and as a common component in the complicated tangle of human motivations.
