The men who did most to promote human happiness were—as might have been expected—those who thought happiness important, not those who despised it in comparison with something more “sublime.” Moreover, a man’s ethic usually reflects his character, and benevolence leads to a desire for the general happiness.

Context

“Or, again, what is valued may be strong emotion; this was the case with the romantics. This led to a toleration of such passions as hatred and revenge; Byron’s heroes are typical, and are never persons of exemplary behaviour. The men who did most to promote human happiness were—as might have been expected—those who thought happiness important, not those who despised it in comparison with something more “sublime.” Moreover, a man’s ethic usually reflects his character, and benevolence leads to a desire for the general happiness. Thus the men who thought happiness the end of life tended to be the more benevolent, while those who proposed other ends were often dominated, unconsciously, by cruelty or love of power. These ethical differences are associated, usually though not invariably, with differences in politics.” source
