Constitutive elements: (a) maximisation principle; (b) welfarist theory of that which must be maximised (happiness, and only happiness); (c) Happiness is to be understood as pleasure, unhappiness as pain; (d) the possibility of making comparative judgment about different forms of pleasure (and, by implication, of pain); (e) the maximisation of happiness and minimisation of pain are not merely the end of all human action: they are also the standards for morality.
Focus of this lecture: what counts as happiness and how, and whether, it can be measured. In other words: Mill’s Utilitarianism as a theory of the good.
