(Deny utility exists?)
The writers who introduced the concept of "utility" were Jeremy Bentham (1748-1832), Thomas Bayes (1702-1761), and Daniel Bernoulli (1700-1782).
Jeremy Bentham, in his 1781 book Principles of Morals and Legislation (still in print), introduced the concept of "utility." He believed that utility in terms of pleasure and pain could be measured numerically on a scale unique up to an affine transformation. It also could be estimated by considering intensity, duration, and degree of certainty of pleasure or pain. One could use it and arithmetic to make interpersonal comparisons and to aggregate individual utilities into a social utility. The philosophy of "utilitarianism" – "the greatest happiness principle" – was invented by Bentham and has been very influential. Bentham wanted to deduce all moral and legal principles from this underlying principle plus logic, arithmetic, and experimental evidence.
How to make social policy decisions: For example (Bentham said), a legislator deciding how to vote on some proposed law should assess (perhaps with the aid of experiments) how much happiness or pain it would lead to for each individual, add these all up to get a social utility, and then vote the way that would maximize social utility.
Important writers often described as Bentham's followers include William Godwin 1756-1836, John Austin 1790-1859, James Mill 1773-1836, John Stuart Mill 1806-1873, Herbert Spencer 1820-1903, Bertrand Russell 1872-1970*, John Von Neumann 1903-1957, John C. Harsanyi 1920-2000*, and Peter Singer 1946- (the *s denote Nobel laureates). Other philosophical or social movements which trace some of their ideas to Bentham and the utilitarians include "social Darwinists," "libertarians," and "animal rights."
In mathematics and probability theory, the concept of "utility" is central to the "Bayesian" school, started by Thomas Bayes and now by far the most important framework in which to view statistics. Daniel Bernoulli also invented the notion of "utility" as a concept in probability theory and gambling distinct from "money." Bernoulli had arguments something like this to prove utility and money were not the same thing:
Bernoulli's (more dramatic) example: You are offered two choices.
These examples prove "utility" is different from "money."
This framework was married to economics in Von Neumann and Morgenstern's book Theory of Games and Economic Behavior (1944 & 1947). This book made the important point that – although some authors had tried to replace "cardinal" (numerical) utilities with mere "ordinals" (non-numerical, defined only by preference relations), this was useless if one were trying to make decisions in the presence of random events or play "games of incomplete information." (Also, ordinals run into problems with "cycles.") The 1947 edition also presented the first axiomatic development of utility.
Bentham's decision-making procedure, note, is extremely similar to range voting. But oddly enough (as far as I can tell from, e.g, examining the book Leslie Stephen: The English Utilitarians, vols I, II, III, 1900), Bentham appears never to have actually thought of range voting. (Later note: Professor Claude Hillinger points out that Harsanyi did think of range voting, or something very similar, in the 1950s, and made the point it evaded Arrow's theorem.

By applying his procedure, Bentham deduced:
