 Based on the scientific evidence, if pleasure comes apart, it will be along such lines, and not along those suggested by concern with intentional structure (between attitude and object) or between sensory pleasure, enjoyment of activities, and so-called propositional pleasure that armchair philosophical and linguistic analysis suggests. But this should come as no surprise. Mood disorders and their therapies do not discriminate along such a priori lines either (Millgram 1997, 124 citing Katz 1986, 119).
