November 7, 1862.--How malign, infectious, and unwholesome is the eternal smile of that indifferent criticism, that attitude of ironical contemplation, which corrodes and demolishes everything, that mocking pitiless temper, which holds itself aloof from every personal duty and every vulnerable affection, and cares only to understand without committing itself to action! Criticism become a habit, a fashion, and a system, means the destruction of moral energy, of faith, and of all spiritual force. One of my tendencies leads me in this direction, but I recoil before its results when I come across more emphatic types of it than myself. And at least I cannot reproach myself with having ever attempted to destroy the moral force of others; my reverence for life forbade it, and my self-distrust has taken from me even the temptation to it. This kind of temper is very dangerous among us, for it flatters all the worst instincts of men--indiscipline, irreverence, selfish individualism--and it ends in social atomism. Minds inclined to mere negation are only harmless in great political organisms, which go without them and in spite of them. The multiplication of them among ourselves will bring about the ruin of our little countries, for small states only live by faith and will. Woe to the society where negation rules, for life is an affirmation; and a society, a country, a nation, is a living whole capable of death. No nationality is possible without prejudices, for public spirit and national tradition are but webs woven out of innumerable beliefs which have been acquired, admitted, and continued without formal proof and without discussion. To act, we must believe; to believe, we must make up our minds, affirm, decide, and in reality prejudge the question. He who will only act upon a full scientific certitude is unfit for practical life. But we are made for action, and we cannot escape from duty. Let us not, then, condemn prejudice so long as we have nothing but doubt to put in its place, or laugh at those whom we should be incapable of consoling! This, at least, is my point of view. * * * * * Beyond the element which is common to all men there is an element which separates them. This element may be religion, country, language, education. But all these being supposed common, there still remains something which serves as a line of demarcation--namely, the ideal. To have an ideal or to have none, to have this ideal or that--this is what digs gulfs between men, even between those who live in the same family circle, under the same roof or in the same room. You must love with the same love, think with the same thought as some one else, if you are to escape solitude.
