This paper argues that happiness and pleasure are distinct states of mind because they stand in a distinct logical relation to belief. Roughly, being happy about a state of affairs s implies that one believes that s satisfies the description ‘s’ and that it is in some way good, whereas taking pleasure in s does not. In particular, Fred Feldman's analysis of happiness in terms of attitudinal pleasure overlooks this distinction.

It is customarily assumed that propositional attitudes present two independent components: a propositional component and a psychological component, in the form of an attitude. These two components are caught by means of two different methods: propositions by some model theoretic theory, psychological attitudes by making appeal to their functional or psychological role. Some authors have seek a convergence by individuating propositions by Functional role semantics. In this paper I show that when it comes to emotional attitudes with propositional content, either (...) the independence of proposition and attitude collapses or functional role semantics brings to unstable individuation conditions for propositions. Some consequences of these two outcomes are considered. (shrink)

Pleasure, in the inclusive usages most important in moral psychology, ethical theory, and the studies of mind, includes all joy and gladness — all our feeling good, or happy. It is often contrasted with similarly inclusive pain, or suffering, which is similarly thought of as including all our feeling bad. Contemporary psychology similarly distinguishes between positive affect and negative affect.[1..
