The likely headquote for the first paper of my dissertation

The insolence and brutality of anger, in the same “manner,” when we indulge its fury without check or restraint, is, of all objects, the most detestable. But we admire that noble and generous resentment which governs its pursuit of the greatest injuries, not by rage which they are apt to excite in the breast of the sufferer, but by the indignation which they naturally call forth in that of the impartial spectator; which allows no word, no gesture, to escape it beyond what this more equitable sentiment would dictate; which never, even in thought, attempts any greater vengeance, nor desires to inflict any greater punishment, than what every indifferent person would rejoice to see executed (p. 267).
