In moral philosophy, consequentialism is a class of normative, teleological ethical theories that holds that the consequences of one's conduct are the ultimate basis for judgement about the rightness or wrongness of that conduct. Thus, from a consequentialist standpoint, a morally right act is one that will produce a good outcome. Consequentialism, along with eudaimonism, falls under the broader category of teleological ethics, a group of views which claim that the moral value of any act consists in its tendency to produce things of intrinsic value. Consequentialists hold in general that an act is right if and only if the act will produce, will probably produce, or is intended to produce, a greater balance of good over evil than any available alternative. Different consequentialist theories differ in how they define moral goods, with chief candidates including pleasure, the absence of pain, the satisfaction of one's preferences, and broader notions of the "general good".
In ethical philosophy, ethical egoism is the normative position that moral agents ought to act 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 that it is rational to act in one's self-interest. Ethical egoism holds, therefore, that actions whose consequences will benefit the doer are ethical.
Ethics is the philosophical study of moral phenomena. Also called moral philosophy, it investigates normative questions about what people ought to do or which behavior is morally right. Its main branches include normative ethics, applied ethics, and metaethics.
In metaphilosophy and ethics, metaethics is the study of the nature, scope, and meaning of moral judgment. It is one of the three branches of ethics generally studied by philosophers, the others being normative ethics and applied ethics.
Normative ethics is the study of ethical behaviour and is the branch of philosophical ethics that investigates questions regarding how one ought to act, in a moral sense.
In ethical philosophy, utilitarianism is a family of normative ethical theories that prescribe actions that maximize happiness and well-being for the affected individuals. In other words, utilitarian ideas encourage actions that ensure the greatest good for the greatest number. Although different varieties of utilitarianism admit different characterizations, the basic idea behind all of them is, in some sense, to maximize utility, which is often defined in terms of well-being or related concepts. For instance, Jeremy Bentham, the founder of utilitarianism, described utility as the capacity of actions or objects to produce benefits, such as pleasure, happiness, and good, or to prevent harm, such as pain and unhappiness, to those affected.
Moral relativism or ethical relativism is used to describe several philosophical positions concerned with the differences in moral judgments across different peoples and cultures. An advocate of such ideas is often referred to as a relativist.
Moral realism is the position that ethical sentences express propositions that refer to objective features of the world, some of which may be true to the extent that they report those features accurately. This makes moral realism a non-nihilist form of ethical cognitivism with an ontological orientation, standing in opposition to all forms of moral anti-realism and moral skepticism, including ethical subjectivism, error theory, and non-cognitivism. Moral realism's two main subdivisions are ethical naturalism and ethical non-naturalism.
Henry Sidgwick was an English utilitarian philosopher and economist and is best known in philosophy for his utilitarian treatise The Methods of Ethics. His work in economics has also had a lasting influence. He was the Knightbridge Professor of Moral Philosophy at the University of Cambridge from 1883 until his death. He was one of the founders and first president of the Society for Psychical Research and a member of the Metaphysical Society and promoted the higher education of women. In 1875, with Millicent Garrett Fawcett, he co-founded Newnham College, a women-only constituent college of the University of Cambridge. It was the second Cambridge college to admit women, after Girton College. In 1856, Sidgwick joined the Cambridge Apostles intellectual secret society.
This index of ethics articles puts articles relevant to well-known ethical debates and decisions in one place - including practical problems long known in philosophy, and the more abstract subjects in law, politics, and some professions and sciences. It lists also those core concepts essential to understanding ethics as applied in various religions, some movements derived from religions, and religions discussed as if they were a theory of ethics making no special claim to divine status.
Virtue ethics is an approach that treats virtue and character as the primary subjects of ethics, in contrast to other ethical systems that put consequences of voluntary acts, principles or rules of conduct, or obedience to divine authority in the primary role.
In moral philosophy, deontological ethics or deontology is the normative ethical theory that the morality of an action should be based on whether that action itself is right or wrong under a series of rules and principles, rather than based on the consequences of the action. It is sometimes described as duty-, obligation-, or rule-based ethics. Deontological ethics is commonly contrasted to consequentialism, utilitarianism, virtue ethics, and pragmatic ethics. In this terminology, action is more important than the consequences.
Ethical subjectivism is the meta-ethical view which claims that:
- Ethical sentences express propositions.
- Some such propositions are true.
- The truth or falsity of such propositions is ineliminably dependent on the attitudes of people.
Rational egoism is the principle that an action is rational if and only if it maximizes one's self-interest. As such, it is considered a normative form of egoism, though historically has been associated with both positive and normative forms. In its strong form, rational egoism holds that to not pursue one's own interest is unequivocally irrational. Its weaker form, however, holds that while it is rational to pursue self-interest, failing to pursue self-interest is not always irrational.
Secular ethics is a branch of moral philosophy in which ethics is based solely on human faculties such as logic, empathy, reason or moral intuition, and not derived from belief in supernatural revelation or guidance—a source of ethics in many religions. Secular ethics refers to any ethical system that does not draw on the supernatural, and includes humanism, secularism and freethinking. A classical example of literature on secular ethics is the Kural text, authored by the ancient Indian philosopher Valluvar.
James Webster Rachels was an American philosopher who specialized in ethics and animal rights.
Kantian ethics refers to a deontological ethical theory developed by German philosopher Immanuel Kant that is based on the notion that "I ought never to act except in such a way that I could also will that my maxim should become a universal law." It is also associated with the idea that "it is impossible to think of anything at all in the world, or indeed even beyond it, that could be considered good without limitation except a good will." The theory was developed in the context of Enlightenment rationalism. It states that an action can only be moral if it is motivated by a sense of duty, and its maxim may be rationally willed a universal, objective law.
The following outline is provided as an overview of and topical guide to ethics.
The Methods of Ethics is a book on ethics first published in 1874 by the English philosopher Henry Sidgwick. The Stanford Encyclopedia of Philosophy indicates that The Methods of Ethics "in many ways marked the culmination of the classical utilitarian tradition." Noted moral and political philosopher John Rawls, writing in the Forward to the Hackett reprint of the 7th edition, says Methods of Ethics "is the clearest and most accessible formulation of ... 'the classical utilitarian doctrine'". Contemporary utilitarian philosopher Peter Singer has said that the Methods "is simply the best book on ethics ever written."
