[194] 1st Series, vol. iii., p. 193: "In the doctrine of interest, every man seeks the useful, but he is not sure of attaining it. He may, by dint of prudence and profound combinations, increase in his favor the chances of success; it is impossible that there should not remain some chances against him; he never pursues, then, any thing but a probable result. On the contrary, in the doctrine of duty, I am always sure of obtaining the last end that I propose to myself, moral good. I risk my life to save my fellow; if, through mischance, I miss this end, there is another which does not, which cannot, escape me,--I have aimed at the good, I have been successful. Moral good, being especially in the virtuous intention, is always in my power and within my reach; as to the material good that can result from the action itself, Providence alone disposes of it. Let us felicitate ourselves that Providence has placed our moral destiny in our own hands, by making it depend upon the good and not upon the useful. The will, in order to act in the sad trials of life, has need of being sustained by certainty. Who would be disposed to give his blood for an uncertain end? Success is a complicated problem, that, in order to be solved, exacts all the power of the calculus of probabilities. What labor and what uncertainties does such a calculus involve! Doubt is a very sad preparation for action. But when one proposes before all to do his duty, he acts without any perplexity. Do what you ought, let come what may, is a motto that does not deceive. With such an end, we are sure of never pursuing it in vain." [195] See the development of the idea of right, lectures 14 and 15. [196] See lecture 14, Theory of liberty.

[201] These words sufficiently mark the generous epoch in which we pronounce them, without wounding the authority and the applauses of a noble youth, when M. de Chateaubriand covered the Restoration with his own glory, when M. Royer-Collard presided over public instruction, M. Pasquier, M. Laine, M. de Serre over justice and the interior, Marshal St. Cyr over war, and the Duke de Richelieu over foreign affairs, when the Duke de Broglie prepared the true legislation of the press, and M. Decazes, the author of the wise and courageous ordinance of September 5, 1816, was at the head of the councils of the crown; when finally, Louis XVIII. separated himself, like Henry IV., from his oldest servants in order to be the king of the whole nation.
