Also, I should have thought that, for Aquinas, all want and pursue happiness, but only the wise want and pursue what happiness consists in: the unwise want and pursue but do not attain happiness, because they are under a misapprehension about what it consists in (e.g., they think it consists in riches, or honor, or the delights of the flesh, or ...), and so “mispursue” happiness, by pursuing things which won't in fact, if attained, bring them happiness (although the mispursuers of happiness think they will).
