Based on Hume's major philosophical works and on some of his Essays, this paper discusses formally the feasibility, from a Humean point of view, of a welfare policy which would aim at promoting the highest individual happiness whereas individual decisions, like individual happiness, are determined not only by allocations of goods, but also by an emotional state. It is shown that both the intertemporal structure of the problem and the role that Hume granted to the ‘calm passion' allow solving the problem, at least in principle.
