Abstract

Aggregation-friendly moral theories such as classical utilitarianism are forced to invest a great deal of ingenuity in damping out and modulating the effects of welfare aggregation. In Mill's treatment, the problem famously appears as the puzzle of how the Principle of Liberty is meant to be compatible with the Principle of Utility, and there have been a great many attempted interpretations of his solution, all, in my view, unsatisfactory. I will first reconstruct Mill's generally unnoticed account of the psychological implementation of higher pleasures; this will allow me to explain what the distinction between higher and lower pleasures was, and how Mill was introduced lexical preference orderings into his theory. Then I will show how the underlying psychological theory permits Mill to argue for the lexical priority of liberty over the goods which liberty allows us to obtain. Finally, I will turn to the Millian considerations omitted from the argument I will have reconstructed. By way of explaining why they are so difficult to accommodate, I will consider why Mill might have abandoned his projected sciences of character. I will take my leave by asking what Mill's failure to turn his implementation analysis of the higher pleasures into an argument expressing the importance of individuality and originality means for us
