Classic utilitarianism was advocated by Jeremy Bentham and John Stuart Mill. In “A Fragment on Government,”Bentham says ‘it is the greatest happiness of the greatest number that is the measure of right and wrong’ and describes this as a fundamental axiom. In “An Introduction to the Principles of Morals and Legislation,” he talks of ‘the principle of utility’ but later prefers “the greatest happiness principle.”
