Hedonism is the philosophy that pleasure is of ultimate importance, the most important pursuit. The name derives from the Greek word for “delight”
The basic idea behind hedonistic thought is that pleasure is the only thing that is good for a person. This is often used as a justification for evaluating actions in terms of how much pleasure and how little pain (i.e. suffering) they produce. In very simple terms, a hedonist strives to maximise this total pleasure (pleasure minus pain).
John Stuart Mill believed that there can be different levels of pleasure – higher quality pleasure is better than lower quality pleasure. Mill also argues that simpler beings (he often references pigs) have an easier access to the simpler pleasures; since they do not see other aspects of life, they can simply indulge in their pleasures. The more elaborate beings tend to spend more thought on other matters and hence lessen the time for simple pleasure. It is therefore more difficult for them to indulge in such “simple pleasures” in the same manner.
Ayn Rand, one of the biggest modern proponents of Egoism, rejected hedonism in a literal sense as a comprehensive ethical system:
To take “whatever makes one happy” as a guide to action means: to be guided by nothing but one’s emotional whims. Emotions are not tools of cognition. . . . This is the fallacy inherent in hedonism–in any variant of ethical hedonism, personal or social, individual or collective. “Happiness” can properly be the purpose of ethics, but not the standard. The task of ethics is to define man’s proper code of values and thus to give him the means of achieving happiness. To declare, as the ethical hedonists do, that “the proper value is whatever gives you pleasure” is to declare that “the proper value is whatever you happen to value”–which is an act of intellectual and philosophical abdication, an act which merely proclaims the futility of ethics and invites all men to play it deuces wild.
