Doubts about the adequacy of appeals to impartial practical reason give those with rationalist sympathies reason to explore the metaphysical, and not merely strategic, reconciliation of prudence and altruism contained in metaphysical egoism. Even if we recognize impartial practical reason, the supremacy of moral demands may depend upon the plausibility of metaphysical egoism. For as long as we recognize the demands of prudence, the conflict between altruism and prudence will threaten altruism's supremacy. We might consider one version of metaphysical egoism that appeals to psychological reductionism about personal identity and exploits some Platonic and Aristotelian analogies between intrapersonal and interpersonal relations and concern.

Those who subscribe to a prudential conception of practical reason do not believe that there is a conflict between other-regarding and self-regarding norms as the former are held to be founded on the latter. Moral conduct, they maintain, is always rationally justifiable. The reasons we should fulfil the demands of other-regarding norms are the same as those we have for fulfilling self-regarding norms. David Brink has put forth an interesting and novel account of this approach to practical reason which he calls ‘metaphysical egoism’. Metaphysical egoism requires that we modify our pre-theoretical understandings of self-interest on metaphysical grounds. I critically assess Brink’s argument and claim that metaphysical egoism does not adequately function as a motive or guide for action. It is susceptible to many of the same problems which strategic egoism faces.

Provides an overview of the theory of psychological egoism—the thesis that we are all ultimately motivated by self-interest. Philosophical arguments for and against the view are considered as well as some empirical evidence.

Weak psychological egoism is the doctrine that anything an agent does intentionally, that agent does at least expecting thereby to realize one of her self-regarding ends. (Strong psychological egoism, by contrast, is the doctrine that agents act always intending thereby to realize a self-regarding end.) Though weak psychological egoism is a doctrine ultimately answerable to empirical evidence, we presently have excellent a priori reasons for accepting it and attempting to construct psychological theories that include it as an organizing principle. These reasons have mainly to do with the idea that to understand the motivation behind an action, we need to understand the force of the consideration that motivates the agent, and the way to do this is to find a self-regarding end associated in the agent''s mind with acting on that consideration.

I will present what I think is the best argument for the version of psychological egoism under consideration here, and explain why I think even that argument fails to go much distance toward establishing it. It turns out, though, I will caution, that defeating that argument means only that we are right to reject psychological egoism as extremely implausible; it does not entitle us to claim to have shown the thesis itself to be either confused and senseless or false. However, my main goal in this paper is neither to refute nor to defend psychological egoism, but rather to show how it, even in a very strong form, manages to survive a number of common objections both to itself and to arguments meant to support it.

Is human behavior exclusively motivated by self-interest? Common sense indicates that we should flatly deny this, or so it seems to me. Yet the doctrine of universal self-interest, psychological egoism for short, has gained the support of many researchers in science. Common sense also seems to allow the rejection of ethical egoism, the doctrine that human behavior should be motivated exclusively by self-interest. It appears to be at variance with widely endorsed moralities. Yet it is a perennial subject of research in ethics. What stance should we take in the face of these discrepancies? Two views suggest themselves. Commonsensical views of egoism and altruism are flawed or research on the subject in science and ethics is misguided. Considering ethics I argue in this article that research is misguided to the extent that it is conducted at inappropriately high levels of generality. I argue that both ethical egoism and psychological egoism are mistaken.

Recently Terrance McConnell has attempted to show that not only does psychological egoism lend no support to ethical egoism but is even incompatible with it. 1 McConneU's attempt has been vitiated by Paul Simpson's critique of the version of psychological egoism that McConnell offered) In this discussion I will consider McConnell's and Simpson's arguments and then offer a version of psychological egoism that avoids Simpson's objections. After showing that one version of ethical egoism is incompatible with that version of psychological egoism, I will consider other versions of ethical egoism in an attempt to find the best version of that moral doctrine. It will turn out that even the best version of ethical egoism is incompatible with the version of psychological egoism that avoids Simpson's criticisms. However, another version of psychological egoism will be offered that is compatible with all versions of ethical egoism and that is also not open to Simpson's objections. An argument will be offered, and then criticized, that seems to lend support to ethical egoism and that rests, in part, on this other version of psychological egoism.

Egoism can be a descriptive or a normative position. Psychological egoism, the most famous descriptive position, claims that each person has but one ultimate aim: her own welfare. Normative forms of egoism make claims about what one ought to do, rather than describe what one does do. Ethical egoism claims that it is necessary and sufficient for an action to be morally right that it maximize one's self-interest. Rational egoism claims that it is necessary and sufficient for an action to be rational that it maximize one's self-interest.
