Context

Each is in some sense worse; for a bad man will do ten thousand times as much evil as a brute. 7 With regard to the pleasures and pains and appetites and aversions arising through touch and taste, to which both self-indulgence and temperance were formerly narrowed down, it possible to be in such a state as to be defeated even by those of them which most people master, or to master even those by which most people are defeated;” source
