Utilitarianism and Punishment

Utilitarianism is the view that the rightness of an action depends entirely on expected utility, that is on the sum of the utilities of its consequences weighted by their various probabilities. I shall distinguish two forms of utilitarianism: hedonistic utilitarianism and preference utilitarianism. In hedonistic utilitarianism it is just a matter of pleasure and its opposite, unpleasure. Often utilitarians have used ‘pain’ instead of ‘unpleasure’, but this has the disadvantage that ‘pain’ can suggest ‘a pain’, and ‘a pain’ is not the opposite of ‘a pleasure’. If I annoy you I give you the opposite of pleasure but I do not necessarily give you a pain. In preference utilitarianism we take value to be satisfaction of desires or preferences. It is a difficult theory to work out in so far as we have to take ‘preference’ here to be intrinsic preference, and so need a clear distinction between intrinsic and extrinsic preferences.
