Ethics
Ethics, also known as moral philosophy, is a branch of philosophy that addresses questions about morality—that is, concepts such as good and evil, right and wrong, virtue and vice, justice and crime, etc.Major branches of ethics include:...

Norm (philosophy)
Norms are concepts of practical import, oriented to effecting an action, rather than conceptual abstractions that describe, explain, and express. Normative sentences imply “ought-to” types of statements and assertions, in distinction to sentences that provide “is” types of statements and assertions...

Ethical egoism
Ethical egoism is the normative ethical position that moral agents ought to do what is in their own self-interest. It differs from psychological egoism, which claims that people can only act in their self-interest. Ethical egoism also differs from rational egoism, which holds merely that it is...

Psychological egoism
Psychological egoism is the view that humans are always motivated by self-interest, even in what seem to be acts of altruism. It claims that, when people choose to help others, they do so ultimately because of the personal benefits that they themselves expect to obtain, directly or indirectly,...

 (where rationality may or may not be tied to morality). Ethical egoism is also different from amoralism.

Philosophy

Rational egoism is discussed by the nineteenth-century English philosopher Henry Sidgwick
Henry Sidgwick
Henry Sidgwick was an English utilitarian philosopher and economist. He was one of the founders and first president of the Society for Psychical Research, a member of the Metaphysical Society, and promoted the higher education of women...

 in The Methods of Ethics. A method of ethics is "any rational procedure by which we determine what individual human beings 'ought' – or what it is 'right' for them – to do, or seek to realize by voluntary action". Sidgwick considers three such procedures, namely, rational egoism, dogmatic intuitionism and utilitarianism
Utilitarianism
Utilitarianism is an ethical theory holding that the proper course of action is the one that maximizes the overall "happiness", by whatever means necessary. It is thus a form of consequentialism, meaning that the moral worth of an action is determined only by its resulting outcome, and that one can...

. Rational egoism is the view that, if rational, "an agent regards quantity of consequent pleasure and pain to himself alone important in choosing between alternatives of action; and seeks always the greatest attainable surplus of pleasure over pain".

Sidgwick found it difficult to find any persuasive reason for preferring rational egoism over utilitarianism
Utilitarianism
Utilitarianism is an ethical theory holding that the proper course of action is the one that maximizes the overall "happiness", by whatever means necessary. It is thus a form of consequentialism, meaning that the moral worth of an action is determined only by its resulting outcome, and that one can...

. Although utilitarianism can be provided with a rational basis and reconciled with the morality of common sense, rational egoism appears to be an equally plausible doctrine regarding what we have most reason to do. Thus we must "admit an ultimate and fundamental contradiction in our apparent intuitions of what is Reasonable in conduct; and from this admission it would seem to follow that the apparently intuitive operation of Practical Reason, manifested in these contradictory judgments, is after all illusory".

Criticism

Two objections to rational egoism are given by the English philosopher Derek Parfit

, who discusses the theory at length in Reasons and Persons. First, from the rational egoist point of view, it is rational to contribute to a pension scheme now, even though this is detrimental to one's present interests (which are to spend the money now). But it seems equally reasonable to maximize one's interests now, given that one's reasons are not only relative to he, but to he as he is now (and not his future self, who is argued to be a "different" person). Parfit also argues that since the connections between the present mental state and the mental state of one's future self may decrease, it is not plausible to claim that one should be indifferent between one's present and future self.

Social sciences

Rational egoism is the standard behavioral postulate of neoclassical economics

 (1906).

In both fields, the postulate has been criticized and defended on a range of empirical and philosophical grounds. For example, in political science, the assumption of rational egoism gives rise to the paradox of voting
Paradox of voting
The paradox of voting, also called Downs paradox, is that for a rational, self-interested voter the costs of voting will normally exceed the expected benefits. Because the chance of exercising the pivotal vote The paradox of voting, also called Downs paradox, is that for a rational,...

 - given the low probability of being decisive, relative to the personal benefit from a change in the outcome, voting in elections is not rational unless the number of electors is very small. Supporters of rational egoism, however, might point out that this argument is not sound because cultural influences might incentivize voting. Additionally, Scott Aaronson notes that the likelihood of one vote being decisive is on the order of the square root of the number of voters, due to the central limit theorem
Central limit theorem
In probability theory, the central limit theorem states conditions under which the mean of a sufficiently large number of independent random variables, each with finite mean and variance, will be approximately normally distributed. The central limit theorem has a number of variants. In its common...

. However, the utility of a vote could be expected to scale linearly with the number of voters, implying that one should vote because its importance outweighs the chance that it will make a difference.

 also discusses a theory that she called 'Rational egoism' (or more specifically: 'Rational self-interest'). She holds that it is both irrational and immoral to act against one's self-interest. Thus, her view is a conjunction of both rational egoism (in the standard sense) and ethical egoism
Ethical egoism
Ethical egoism is the normative ethical position that moral agents ought to do what is in their own self-interest. It differs from psychological egoism, which claims that people can only act in their self-interest. Ethical egoism also differs from rational egoism, which holds merely that it is...
