Utilitarianism - Historical Background

Historical Background

The importance of happiness as an end for humans has long been recognized. Forms of hedonism were put forward by Aristippus and Epicurus; Aristotle argued that eudaimonia is the highest human good and Augustine wrote that "all men agree in desiring the last end, which is happiness." Happiness was also explored in depth by Aquinas However, utilitarianism as a distinct ethical position only emerged in the eighteenth century.

Although utilitarianism is usually thought to start with Jeremy Bentham there were earlier writers who presented theories that were strikingly similar. In An Enquiry Concerning the Principles of Morals David Hume writes:

In all determinations of morality, this circumstance of public utility is ever principally in view; and wherever disputes arise, either in philosophy or common life, concerning the bounds of duty, the question cannot, by any means, be decided with greater certainty, than by ascertaining, on any side, the true interests of mankind.

Hume had studied under Francis Hutcheson and it was he who first introduced a key utilitarian phrase. In An Inquiry into the Original of Our Ideas of Beauty and Virtue (1725) Hutcheson writes,

In comparing the moral qualitys of actions, in order to regulate our election among various actions proposed, or to find which of them has the greatest moral excellency, we are led by our moral sense of virtue to judge thus; that in equal degrees of happiness, expected to proceed from the action, the virtue is in proportion to the number of persons to whom the happiness shall extend (and here the dignity, or moral importance of persons, may compensate numbers); and in equal numbers, the virtue is as the quantity of the happiness, or natural good; or that the virtue is in a compound ratio of the quantity of good, and number of enjoyers. In the same manner, the moral evil, or vice, is as the degree of misery, and number of sufferers; so that, that action is best, which procures the greatest happiness for the greatest numbers; and that, worst, which, in like manner, occasions misery.

In the first three editions of the book Hutcheson followed this passage with various mathematical algorithms “to compute the Morality of any Actions.” In this he pre-figured the hedonic calculus of Bentham.

It is claimed that the first systematic theory of utilitarian ethics was developed by John Gay. In Concerning the Fundamental Principle of Virtue or Morality (1731) Gay argues that

“happiness, private happiness, is the proper or ultimate end of all our actions… each particular action may be said to have its proper and peculiar end…(but)…. they still tend or ought to tend to something farther; as is evident from hence, viz. that a man may ask and expect a reason why either of them are pursued: now to ask the reason of any action or pursuit, is only to enquire into the end of it: but to expect a reason, i.e. an end, to be assigned for an ultimate end, is absurd. To ask why I pursue happiness, will admit of no other answer than an explanation of the terms.”

This pursuit of happiness is given a theological basis:

“Now it is evident from the nature of God, viz. his being infinitely happy in himself from all eternity, and from his goodness manifested in his works, that he could have no other design in creating mankind than their happiness; and therefore he wills their happiness; therefore the means of their happiness: therefore that my behaviour, as far as it may be a means of the happiness of mankind, should be such…thus the will of God is the immediate criterion of Virtue, and the happiness of mankind the criterion of the wilt of God; and therefore the happiness of mankind may be said to be the criterion of virtue, but once removed…(and)… I am to do whatever lies in my power towards promoting the happiness of mankind.

Gay’s theological utilitarianism was developed and popularized by William Paley. It has been claimed that Paley was not a very original thinker and that the philosophical part of his treatise on ethics is “an assemblage of ideas developed by others and is presented to be learned by students rather than debated by colleagues.” Nevertheless, his book The Principles of Moral and Political Philosophy (1785) was a required text at Cambridge and Smith says that Paley’s writings were “once as well known in American colleges as were the readers and spellers of William McGuffey and Noah Webster in the elementary schools.” Although now largely missing from the philosophical canon, Schneewind writes that "utilitarianism first became widely known in England through the work of William Paley." The now forgotten significance of Paley can be judged from the title of Birks's 1874 work Modern Utilitarianism or the Systems of Paley, Bentham and Mill Examined and Compared.

Apart from restating that happiness as an end is grounded in the nature of God, Paley also discusses the place of rules. He writes,

“…actions are to be estimated by their tendency. Whatever is expedient, is right. It is the utility of any moral rule alone, which constitutes the obligation of it.

But to all this there seems a plain objection, viz. that many actions are useful, which no man in his senses will allow to be right. There are occasions, in which the hand of the assassin would be very useful… The true answer is this; that these actions, after all, are not useful, and for that reason, and that alone, are not right.

To see this point perfectly, it must be observed that the bad consequences of actions are twofold, particular and general. The particular bad consequence of an action, is the mischief which that single action directly and immediately occasions. The general bad consequence is, the violation of some necessary or useful general rule…

You cannot permit one action and forbid another, without showing a difference between them. Consequently, the same sort of actions must be generally permitted or generally forbidden. Where, therefore, the general permission of them would be pernicious, it becomes necessary to lay down and support the rule which generally forbids them.”
