The authors demonstrate that unselfish behavior is in fact an important feature of both biological and human nature. Their book provides a panoramic view of altruism throughout the animal kingdom--from self-sacrificing parasites to the human capacity for selflessness--even as it explains the evolutionary sense of such behavior.

In the present paper I wish to argue that psychological egoism may well have a basis in the empirical facts of human psychology. Certain contemporary learning theorists, e.g., Hull and Skinner, have put forward behavioristic theories of the origin and functioning of human motives which posit a certain number of basically "selfish, " unlearned primary drives or motives (like hunger, thirst, sleep, elimination, and sex), explain all other, higher-order, drives or motives as derived genetically from the primary ones via certain (...) "laws of reinforcement," and, further, deny the "functional autonomy" of those higher-order drives or motive. Now it is a hotly debated issue in contemporary Learning Theory whether any theory such as we have described briefly above could adequately explain adult human behavior. I shall, however, argue only that a theory of the above kind may well be true, and that from such a theory, fortified only by one additional psychological premise, the truth of egoism (non-altruism) logically follows. I hope to show, thereby, that the question of psychological egoism is still an open empirical issue, however fallacious be the philosophical arguments for it. (shrink)

Are our efforts to help others ever driven solely by altruistic motivation, or is our ultimate goal always some form of self- benefit (egoistic motivation)? This volume reports the development of an empirically-testable theory of altruistic motivation and a series of experiments designed to test that theory. It sets the issue of egoism versus altruism in its larger historical and philosophical context, and brings diverse experiments into a single, integrated argument. Readers will find that this book provides a solid base (...) of information from which questions surrounding the existence of altruistic motivation can be further investigated. (shrink)

In philosophy, egoism is the theory that one’s self is, or should be, the motivation and the goal of one’s own action. Egoism has two variants, descriptive or normative. The descriptive (or positive) variant conceives egoism as a factual description of human affairs. That is, people are motivated by their own interests and desires, and they cannot be described otherwise. The normative variant proposes that people should be so motivated, regardless of what presently motivates their behavior. Altruism is the opposite (...) of egoism. The term “egoism” derives from “ego,” the Latin term for the English word “I”. “Egoism” should be distinguished from “egotism,” which means a psychological overvaluation of one’s own importance, or of one’s own activities.

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. (shrink)

The purpose of this paper is to argue for psychological egoism, i.e., the view that the ultimate motivation for all human action is the agent’s self-interest. Two principal opponents to psychological egoism are considered. These two views are shown to make human action inexplicable. Since the reason for putting forward these views is to explain human action, these views fail. If psychological egoism is the best explanation of human action, then humans will not differ as regards their motivations for their (...) actions. However, humans will differ as regards their knowledge of what is in fact in their self-interest. (shrink)
