Consequentialism

A family of normative ethical theories on which an act, rule, motive, institution, or other evaluand has its moral status solely in virtue of the value of the relevant consequences under a declared account of value, scope, information, and choice.

Core Idea

Consequentialism is a family of normative views united by a dependence thesis: the normative status of an evaluand depends only on relevant consequences. In its most familiar form, whether an act is morally right depends only on consequences of the act or of a related object such as the rule under which it falls. The family does not by itself say that pleasure is the only good, that agents must maximize, that actual rather than expected outcomes matter, or that each act is evaluated directly. Those are parameters that specify a consequentialist theory. The Stanford Encyclopedia's current account emphasizes this modularity and distinguishes consequence dependence from the additional claims composing classical utilitarianism.

Judge It by What Happens

Consequentialism is the idea that whether doing something is right or wrong depends only on what happens because of it. If sharing your toy leads to good things, then sharing was right because of how things turned out. People who think this way still argue about which results count as good.

Judging by Results Only

Consequentialism is a family of ideas about right and wrong. They all agree on one thing: whether an action, or a rule, is right depends only on its results. But they can disagree about details, like which results count as good, whether you must pick the very best result or just a good enough one, and whether to judge each action or the rules behind it. Utilitarianism, which counts happiness and pain, is the best-known member of the family, but not the only one. If a view says promises or rights matter on their own, no matter the results, then it isn't consequentialism, even if it thinks results matter too.

Outcome-Only Moral Theories

Consequentialism is a family of moral theories sharing one core claim: the moral status of something, most often an act, depends only on its relevant consequences. That core leaves several choices open, and a full theory must fill them in: what is evaluated (acts, rules, motives, policies), which consequences count (actual, expected, foreseeable, intended), what makes outcomes good (pleasure, preferences, several goods, rights), how outcomes are compared (maximizing, satisficing, prioritizing the worse off, thresholds), and whose consequences count. Classical utilitarianism, associated with Bentham, is one combination: judge acts directly, count pleasure and pain, add them up across everyone, and maximize. Rejecting hedonism or maximizing doesn't mean rejecting consequentialism. But a view that treats consequences as only one factor, letting duties, rights, or intentions settle rightness independently, is not consequentialist.

 

Consequentialism is a family of normative views united by a dependence thesis: the normative status of an evaluand depends only on its relevant consequences, most familiarly that an act's rightness depends only on the consequences of the act or of a related object such as the rule it falls under. The family is modular. A complete theory specifies an evaluand (act, rule, motive, character, institution, policy, practice), a consequence relation (actual, expected, foreseeable, intended, rule-produced), an axiology ranking outcomes (welfare, preference satisfaction, plural goods, rights fulfillment), an aggregation or comparison rule (maximizing, satisficing, prioritarian, egalitarian, threshold), and an agent and population scope, including whether reasons are agent-neutral or agent-relative. Utilitarianism is the paradigm but not a synonym: Bentham's hedonic calculus and classical utilitarianism combine act evaluation, hedonism, aggregation, maximization, and impartiality, and rejecting any of these does not by itself abandon consequentialism. Conversely, treating consequences as one factor among promises, rights, desert, or duties that can fix status independently is not consequentialist. Anscombe introduced the term in Modern Moral Philosophy, though her usage does not map neatly onto later taxonomies distinguishing direct and indirect, actual and expected, maximizing and satisficing, and global or scalar forms. Scheffler's work on agent-centered prerogatives marks the boundary between pure consequence-based criteria and hybrid views.

Scope of Application

Consequentialism is literal when a normative theory makes moral or other normative status depend exclusively on a declared consequence-ranking structure, rather than merely consulting outcomes among independent considerations.

• Act evaluation. Comparing available acts through their relevant consequences.
• Rule evaluation. Assessing general rules by the consequences of their acceptance, practice, or internalization.
• Motive or character evaluation. Ranking dispositions through the outcomes they characteristically produce.
• Institutional ethics. Comparing laws and institutions through population consequences under a declared axiology.
• Population ethics. Handling number, identity, distribution, and future-person questions in outcome rankings.
• Risk and uncertainty. Distinguishing actual, expected, foreseeable, and evidence-relative standards.
• Applied ethics. Making health, environment, technology, or war judgments while keeping moral theory separate from empirical forecasts.
• History of moral philosophy. Classifying theories cautiously under historically appropriate parameters.

Clarity

A clear claim states the evaluand, feasible alternatives, causal or probabilistic consequence model, axiology, affected population, time horizon, aggregation rule, information condition, and decision criterion. It identifies whether consequences of the act, rule, motive, policy, or acceptance practice are assessed. It says whether the theory gives binary rightness, an ordering, or degrees of moral value.

Manages Complexity

Consequentialism offers a powerful compression: heterogeneous acts and institutions can be compared through the states of affairs they produce and a common value ranking. This exposes opportunity costs, indirect effects, distribution, uncertainty, and long horizons that rule-by-rule intuition may miss. The compression transfers complexity into forecasting and axiology. Consequences branch, probabilities are uncertain, persons and times may be incommensurable, and a single aggregate can conceal severe distributional harms.

Abstract Reasoning

1. Specify the object receiving normative evaluation and the available alternatives.
2. Choose the consequence bearer: act, rule, motive, institution, or acceptance practice.
3. Construct a consequence model with causal scope, time horizon, probabilities, and indirect effects.
4. Declare the goods, bads, rights realizations, preferences, or plural values used to rank outcomes.
5. Specify whose outcomes count and how persons, times, and states are aggregated or prioritized.

Knowledge Transfer

Consequentialism transfers a disciplined evaluative pattern: define alternatives, model downstream states, rank them under an explicit value function, and make the dependence of the verdict visible. Policy analysis and engineering can borrow that pattern without becoming moral consequentialism, because their adequacy standards may be institutional or technical rather than ethical. Within ethics, the parameter decomposition supports genuine comparison: two theories can share consequence dependence while differing on value, uncertainty, distribution, or evaluand. It also reveals pseudo-disputes where parties agree on moral structure but use different empirical forecasts.
