1 In so far as a man is determined to an action through 2 having inadequate ideas, he is passive (III. i.), that is (III. 3 Deff. i., and iii.), he does something, which cannot be perceived 4 solely through his essence, that is (by IV. Def. viii.), which 5 does not follow from his virtue. But, in so far as he is 6 determined for an action because he understands, he is active; 7 that is, he does something, which is perceived through his 8 essence alone, or which adequately follows from his virtue. 9 Q.E.D. 10 11
