Abstract

Such is John Stuart Mill's succinct exposition of the core of utilitarian theory. A contemporary philosopher has aptly described utilitarianism as ‘the combination of two principles: (1)the consequentialist principlethat the rightness, or wrongness, of an action is determined by the goodness, or badness, of the results that flow from it and (2)the hedonist principlethat the only thing that is good in itself is pleasure and the only thing bad in itself is pain. Although the consequentialistprinciple has attracted the most attention in modern discussions of utilitarianism, it is the second principle which invites immediate comparison with the views of Plato. I propose therefore to start by comparing the Platonic and the utilitarian conceptions of the good in the hope that this will enable us to see too in what sense Plato's position is consequentialist, and whether his ethical and political theories in general can properly be described as utilitarian.
