The doubt is, whether [Greek] or [Greek] is the subject of the sentence. It is translated as above, not merely with reference to the sense of this passage, but on a comparison with a similar one in Book X. chap 8. [Greek].
The terms are borrowed from the Seventh Book and are here used in their strict philosophical meaning. The [Greek: enkrates] is he who has bad or unruly appetites, but whose reason is strong enough to keep them under. The [Greek: akrates] is he whose appetites constantly prevail over his reason and previous good resolutions. By the law of habits the former is constantly approximating to a state in which the appetites are wholly quelled. This state is called [Greek: sophrosyne], and the man in it [Greek: sophron]. By the same law the remonstrances of reason in the latter grow fainter and fainter till they are silenced for ever. This state is called [Greek: akolasia], and the man in it [Greek: akolastos].
