Egoism¶
A family of descriptive and normative views that gives the self, self-interest, or one's own will a central role in explaining or guiding action.
Core Idea¶
Egoism is a family of views centering an agent's own interest or will. Psychological egoism describes motivation; rational or ethical egoism prescribes reasons or conduct, and the move between them requires argument. Psychological egoism needs a possible counterexample; redefining every sacrifice as hidden satisfaction makes it unfalsifiable. Ethical egoism has a different burden when agents' interests conflict: it must justify why each should privilege their own good. Both questions differ from the ordinary truth that self-care and long-term prudence can be legitimate.
Scope of Application¶
Egoism applies to theories of motivation, practical reason, and ethics when the self-regarding claim and logical status are explicit. Use it only after naming the agent, self-regarding end, descriptive or normative status, and time horizon; an isolated selfish act or cooperative outcome does not settle the theory.
- Moral psychology. Tests motivation claims.
- Practical reason. Assesses self-interest as reason.
- Ethics. Evaluates ethical egoism.
- Political philosophy. Studies interest and cooperation.
- Intellectual history. Compares egoist traditions.
Clarity¶
Always say descriptive or normative and define self-interest. Moving from 'people do' to 'people should' is a logical shift, not a change of emphasis. The closest near miss sets the boundary: Psychological egoism is the closest subtype/near neighbor: it is a universal descriptive thesis, whereas egoism also includes rational and ethical prescriptions.
Manages Complexity¶
Motives, reasons, outcomes, identity, and time horizon can diverge. The family label organizes them but cannot determine whether one action is egoistic without its reason. Universal psychological egoism faces a special evidentiary problem: redescribing every sacrifice as hidden self-satisfaction can make the thesis difficult to falsify. A substantive version must say what observation would count against self-interested motivation. Ethical egoism faces a different burden because conflicts among agents' interests require a rule for why each person should privilege their own good while recognizing others may do the same. Neither issue is resolved by noting that self-care can be legitimate. The theory's exclusivity and justification must be assessed separately from the ordinary prudential truth that agents have responsibilities to themselves. The central description–prescription tradeoff is this: Observed motivation cannot by itself yield duty. A second immediate appetite–durable interest tension matters because Self-regard can require resisting present desire.
Abstract Reasoning¶
Use three linked moves: identify the theory's descriptive or normative status; define the relevant self and interest/will; separate motive, reason, and consequence. As a collapse test, the identity fails when self-reference is incidental rather than the organizing explanatory or normative principle. A fourth check is to test long- versus short-term framing.
Knowledge Transfer¶
Self-regarding optimization in economics or AI is analogy unless an agent, interests, and normative or motivational thesis are present. Literal egoism is philosophical. No canonical parent prime is currently asserted; broader structural comparisons remain related-prime analogies until separately adjudicated in the DAG. It supplies many egoist ends.
Neighborhood in Abstraction Space¶
Egoism sits in a moderately populated region (44th percentile for distinctiveness): it has near-neighbors but no dense thicket of look-alikes.
