 Importantly, to ascribe happiness in the well-being sense is to make a value judgment: namely, that the person has whatever it is that benefits a  person.[1]  If you and I and have different values, then we may well differ about which lives we consider happy. I might think Genghis Khan had a happy life, because I think what matters for well-being is getting what you want; while you deny this because you think a life of evildoing, however “successful,” is sad and impoverished.
