Whence this difference? It is proper to search out its caùse, for it will reveal to us the existence of an irresistible power, public opinion, which, like the atmosphere, surrounds and envelops us so thoroughly that we cease to perceive it. Rousseau never said anything truer than this: Il faut beaucoup de philosophie pour observer les faits qui sont trop près de nous—-"You need much philosophy to observe accurately things which are under your nose."
A thief for the very reason that he does his work secretly, has always public opinion against him. He frightens all who are within his reach. Yet if he has associates, he takes pride in displaying before them his skill and prowess. Here we begin to perceive the force of opinion; for the applause of his accomplices takes away the sense of guilt, and even prompts him to glory in his shame.
The warrior lives in a different medium. The public opinion which brands him is elsewhere, among the nations he has conquered, and he does not feel its pressure. The public opinion at home applauds and sustains him. He and his companions in arms feel sensibly the bond which imites them. The country which has created enemies, and brought danger upon herself, feels it necessary to extol the bravery of her sons. She decrees to the boldest, who have enlarged her frontiers, or brought her, in the greatest amount of booty, honours, renown, and glory. Poets sing their exploits, and ladies twine wreaths and garlands for them. And such is the power of public opinion that it takes from spoliation all idea of injustice, and from the spoliator all sense of wrongdoing.
The public opinion which reacts against military spoliation makes itself felt, not in the conquering, but in the conquered, country, and exercises little influence. And yet it is not altogether inoperative, and makes itself the more felt in proportion as nations have more frequent intercourse, and understand each other better. In consequence, we see that the study of languages, and a freer communication between nations, tends to bring about and render predominant a stronger feeling against this species of spoliation.
Unfortunately, it not unfrequently happens that the nations which surround an aggressive and warlike people are themselves given to spoliation when they can accomplish it, and thus become imbued with the same prejudices.
In that case there is only one remedy—time; and nations must be taught by painful experience the enormous evils of mutual spoliation.
We may note another check—a superior and growing morality. But the object of this is to multiply virtuous actions. How then can morality restrain acts of spoliation when public opinion places such acts in the rank of the most exalted virtue? What more powerful means of rendering a people moral than religion? And what religion more favourable to peace than Christianity? Yet what have we witnessed for eighteen hundred years? During all these ages we have seen men fight, not only in spite of their religion, but in name of religion itself.
The wars waged by a conquering nation are not always offensive and aggressive wars. Such a nation is sometimes so unfortunate as to be obliged to send its soldiers into the field to defend the domestic hearth, and to protect its families, its property, its independence, and its liberty. War then assumes a character of grandeur and sacredness. The national banner, blessed by the ministers of the God of peace, represents all that is most sacred in the land; it is followed as the living image of patriotism and of honour; and warlike virtues are extolled above all other virtues. But when the danger is past, public opinion still prevails; and by the natural reaction of a spirit of revenge, which is mistaken for patriotism, the banner is paraded from capital to capital. It is in this way that nature seems to prepare a punishment for the aggressor.
It is the fear of this punishment, and not the progress of philosophy, which retains arms in the arsenals; for we cannot deny that nations the most advanced in civilization go to war, and think little of justice when they have no reprisals to fear, as the Himalaya, the Atlas, and the Caucasus bear witness.
If religion is powerless, and if philosophy is equally powerless, how then are wars to be put an end to?
