Since every single action of a man's life seems to possess the freedom and originality which in truth only belong to his character as he apprehends it, and the mere apprehension of it by his intellect is what constitutes his career; and since what is original in every single action seems to the empirical consciousness to be always being performed anew, a man thus receives in the course of his career the strongest possible moral lesson. Then, and not before, he becomes thoroughly conscious of all the bad sides of his character. Conscience accompanies every act with the comment: _You should act differently_, although its true sense is: _You could be other than you are_. As the result of this immutability of character on the one hand, and, on the other, of the strict necessity which attends all the circumstances in which character is successively placed, every man's course of life is precisely determined from Alpha right through to Omega. But, nevertheless, one man's course of life turns out immeasurably happier, nobler and more worthy than another's, whether it be regarded from a subjective or an objective point of view, and unless we are to exclude all ideas of justice, we are led to the doctrine which is well accepted in Brahmanism and Buddhism, that the subjective conditions in which, as well as the objective conditions under which, every man is born, are the moral consequences of a previous existence. Macchiavelli, who seems to have taken no interest whatever in philosophical speculations, is drawn by the keen subtlety of his very unique understanding into the following observation, which possesses a really deep meaning. It shows that he had an intuitive knowledge of the entire necessity with which, characters and motives being given, all actions take place. He makes it at the beginning of the prologue to his comedy _Clitia_. _If_, he says, _the same men were to recur in the world in the way that the same circumstances recur, a hundred years would never elapse without our finding ourselves together once more, and doing the same things as we are doing now--Se nel mondo tornassino i medesimi uomini, como tornano i medesimi casi, non passarebbono mai cento anni che noi non ci trovassimo un altra volta insieme, a fare le medesime cose che hora_. He seems however to have been drawn into the remark by a reminiscence of what Augustine says in his _De Civitate Dei_, bk. xii., ch. xiii.
