This is an incomplete list of advocates of utilitarianism and/or consequentialism.
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".
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.
Hedonism is a family of philosophical views that prioritize pleasure. Psychological hedonism is the theory that the underlying motivation of all human behavior is to maximize pleasure and avoid pain. As a form of egoism, it suggests that people only help others if they expect a personal benefit. Axiological hedonism is the view that pleasure is the sole source of intrinsic value. It asserts that other things, like knowledge and money, only have value insofar as they produce pleasure and reduce pain. This view divides into quantitative hedonism, which only considers the intensity and duration of pleasures, and qualitative hedonism, which holds that the value of pleasures also depends on their quality. The closely related position of prudential hedonism states that pleasure and pain are the only factors of well-being. Ethical hedonism applies axiological hedonism to morality, arguing that people have a moral obligation to pursue pleasure and avoid pain. Utilitarian versions assert that the goal is to increase overall happiness for everyone, whereas egoistic versions state that each person should only pursue their own pleasure. Outside the academic context, hedonism is a pejorative term for an egoistic lifestyle seeking short-term gratification.
John Stuart Mill was an English philosopher, political economist, politician and civil servant. One of the most influential thinkers in the history of liberalism, he contributed widely to social theory, political theory, and political economy. Dubbed "the most influential English-speaking philosopher of the nineteenth century" by the Stanford Encyclopedia of Philosophy, he conceived of liberty as justifying the freedom of the individual in opposition to unlimited state and social control. He advocated political and social reforms such as proportional representation, the emancipation of women, and the development of labour organisations and farm cooperatives. The Columbia Encyclopedia 5th ed. says of him "at times Mill came close to socialism, a theory repugnant to his predecessors." He was a proponent of utilitarianism, an ethical theory developed by his predecessor Jeremy Bentham. He contributed to the investigation of scientific methodology, though his knowledge of the topic was based on the writings of others, notably William Whewell, John Herschel, and Auguste Comte, and research carried out for Mill by Alexander Bain. He engaged in written debate with Whewell.
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 lead to 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.
Jeremy Bentham was an English philosopher, jurist, and social reformer regarded as the founder of modern utilitarianism.
Henry Sidgwick was a British 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.
Richard Mervyn Hare, usually cited as R. M. Hare, was a British moral philosopher who held the post of White's Professor of Moral Philosophy at the University of Oxford from 1966 until 1983. He subsequently taught for a number of years at the University of Florida. His meta-ethical theories were influential during the second half of the twentieth century.
Virtue ethics is a philosophical 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.
Utilitarianism is an 1861 essay written by English philosopher and economist John Stuart Mill, considered to be a classic exposition and defense of utilitarianism in ethics. It was originally published as a series of three separate articles in Fraser's Magazine in 1861 before it was collected and reprinted as a single work in 1863. The essay explains utilitarianism to its readers and addresses the numerous criticism against the theory during Mill's lifetime. It was heavily criticized upon publication; however, since then, Utilitarianism gained significant popularity and has been considered "the most influential philosophical articulation of a liberal humanistic morality that was produced in the nineteenth century."
Rule utilitarianism is a form of utilitarianism that says an action is right as it conforms to a rule that leads to the greatest good, or that "the rightness or wrongness of a particular action is a function of the correctness of the rule of which it is an instance". Philosophers Richard Brandt and Brad Hooker are major proponents of such an approach.
Act utilitarianism is a utilitarian theory of ethics that states that a person's act is morally right if and only if it produces the best possible results in that specific situation. Classical utilitarians, including Jeremy Bentham, John Stuart Mill, and Henry Sidgwick, define happiness as pleasure and the absence of pain.
British philosophy refers to the philosophical tradition of the British people. "The native characteristics of British philosophy are these: common sense, dislike of complication, a strong preference for the concrete over the abstract and a certain awkward honesty of method in which an occasional pearl of poetry is embedded".
Paul Joseph Kelly is Professor of Political Philosophy at the London School of Economics and Political Science (LSE), and Head of the Department of Government.
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."
Roger Stephen Crisp is fellow and tutor in philosophy at St. Anne's College, Oxford. He holds the university posts of Professor of Moral Philosophy and Uehiro Fellow and Tutor in Philosophy. His work falls principally within the field of ethics, in particular metaethics, normative ethics, and applied ethics. In addition, he is chairman of the Management Committee of the Oxford Uehiro Centre for Practical Ethics.
Pragmatic ethics is a theory of normative philosophical ethics and meta-ethics. Ethical pragmatists such as John Dewey believe that some societies have progressed morally in much the way they have attained progress in science. Scientists can pursue inquiry into the truth of a hypothesis and accept the hypothesis, in the sense that they act as though the hypothesis were true; nonetheless, they think that future generations can advance science, and thus future generations can refine or replace their accepted hypotheses. Similarly, ethical pragmatists think that norms, principles, and moral criteria are likely to be improved as a result of inquiry.
Negative consequentialism is a version of consequentialism, which is "one of the major theories of normative ethics." Like other versions of consequentialism, negative consequentialism holds that moral right and wrong depend only on the value of outcomes. That is, for negative and other versions of consequentialism, questions such as "what should I do?" and "what kind of person should I be?" are answered only based on consequences. Negative consequentialism differs from other versions of consequentialism by giving greater weight in moral deliberations to what is bad than what is good. Due to this, it can be considered an instance of what has been called "suffering-focused ethics", the view that the reduction of suffering has moral priority over any other possible duties we may think of.
Katarzyna de Lazari-Radek is a Polish utilitarian philosopher and a university professor at the Institute of Philosophy at University of Łódź.
Happiness is the only thing of real value in existence
As all men desire their own happiness, praise or blame is bestowed on actions and motives, according as they lead to this end; and as happiness is an essential part of the general good, the greatest-happinesss principle indirectly serves as a nearly safe standard of right and wrong.
