 Happiness may be thought important even on theories normally believed to take a dismissive view of it. Aristotelians identify well-being with virtuous activity, yet Aristotle plainly takes this to be a highly pleasant condition, indeed the most pleasant kind of life there is (see, e.g., NE, Bk. I 8; Bk. VII 13). You cannot flourish, on Aristotelian terms, without being happy, and unhappiness is clearly incompatible with well-being. Even the Stoics, who notoriously regard all but a virtuous inner state as at best indifferent, would still assign happiness a kind of importance: at the very least, to be unhappy would be unvirtuous; and virtue itself arguably entails a kind of happiness, namely a pleasant state of tranquility. As well, happiness would likely be a preferred indifferent in most cases, to be chosen over unhappiness. To be sure, both Aristotelian and Stoic accounts are clear that happiness alone does not suffice for well-being, that its significance is not what common opinion takes it to be, and that some kinds of happiness can be worthless or even bad. But neither denies that happiness is somehow quite important for human well-being.
