A first form of utilitarianism is found in the Chinese philosopher Mozi (479-381 BC). He founded the school of Mohism in ancient China and advocated a utilitarian ethic some 2200 years before one was formulated as a justifiable principle in Europe. Ancient hedonism, which goes back to the Cyrenaic school of philosophers founded by Aristippus of Cyrene, can also be interpreted in the broadest sense as a predecessor of classical utilitarianism.
The beginnings of utilitarian thought in modern Europe are found in Thomas Hobbes (Leviathan), whose basic ethical proposition is that "right" behavior is that which promotes our own well-being. Further, the justification of society's moral code depends on whether it promotes the well-being of those who follow it. With Francis Hutcheson, the criterion for morally good action was whether it promoted the welfare of humanity. His successor David Hume concluded that virtue and personal merit rest in those of our qualities that are useful to us - and to others.
Classic period
Jeremy Bentham was the first in Europe to advocate utilitarian ethics in the form of an elaborate system. In his work An introduction to the Principles of Morals and Legislation, Bentham expressed that for him there were only two basic anthropological constants: The pursuit of pleasure and the avoidance of pain. Suffering and pleasure, according to Bentham, determined the ethical criteria of human action and the causality of our actions. It is nature, he said, that guides man's path in suffering and pleasure. Bentham saw suffering and pleasure as the decisive motives for human action and thus advocated a psychological hedonism:
"Nature has placed mankind under the dominion of two sovereign masters - Sorrow and Joy. It is for them alone to point out what we should do, as well as to determine what we will do. Both the standard of right and wrong, and the chain of causes and effects, are fastened to their throne. They rule us in all we do, in all we say, in all we think."
According to Bentham, a person always strives for an object that he expects to give pleasure. From this, Bentham formulated the principle of utility, which states that all that is good is that which produces "the greatest happiness of the greatest number". Bentham later realized that the simultaneous maximization of two quantities does not provide a unique solution, which is why he later spoke only of the "Maximum Happiness Principle". Bentham's work focused on the application of this principle to the design of social order. In his writings, he developed not so much an individual ethic as a rational legislative theory. For Bentham, the quantity of happiness alone was decisive, which he expressed by the drastic phrase "Pushpin is of equal value [...] with poetry" ("Prejudice apart, the game of push-pin is of equal value with the arts and sciences of music and poetry. ") expressed. In contrast, John Stuart Mill (1806-1873), in his 1863 book "Utilitarianism", argued that cultural, intellectual and spiritual satisfaction also had a qualitative value, compared to physical satisfaction. A person who has experienced both prefers spiritual satisfaction to physical satisfaction. Mill states this in his famous saying:
"It is better to be a discontented man than a contented pig; better to be a discontented Socrates than a contented fool."
However, the calculative mapping of qualitatively preferable activities remains unclear. Moreover, Mill's distinction seems to be rather conventional and based on a particular notion of high culture at the time.
Also in the writing "On Liberty" John Stuart Mill set different accents than his father's friend and teacher, Bentham. Whereas in a pure utility calculus freedom cannot be a value in itself, Mill here attaches a fundamental value to freedom and especially to freedom of speech. In order to discern truth, all relevant arguments must be examined. However, this is impossible if opinions and arguments are politically suppressed. The correct determination of the greatest happiness thus presupposes freedom of expression (freedom of the press, freedom of science, etc.).
This libertarian version of utilitarianism is also found in the political philosophy of Bertrand Russell (1872-1970).
Later forms
The classical utilitarianism of Bentham and Mill influenced many other philosophers and led to the development of a broader concept of consequentialism. The hedonistic utilitarianism of Bentham and Mill, although best known, is now held by only a minority. More advanced variants of utilitarianism, improved in the face of criticism, were developed by William Godwin (1756-1836), a contemporary of Bentham with anarchist tendencies, and Henry Sidgwick (1838-1900), among others. In more recent times, the most notable are Richard Mervyn Hare (1919-2002), Richard Brandt (1910-1997), who coined the term "rule utilitarianism", John Jamieson Carswell Smart, and Peter Singer, who was long a proponent of preference utilitarianism, but for some years has advocated the classical, hedonistic variant of utilitarianism. Ludwig von Mises argued for liberalism using utilitarian arguments. Conversely, some philosophers advocated ethical socialism on a utilitarian basis.
As the examples show, utilitarianism is mainly widespread in the English-speaking world. One of the few German representatives is the philosopher Dieter Birnbacher from Düsseldorf, who has also emerged as a translator of John Stuart Mill.
