Tocqueville discusses the ways that self-​interest disciplines people in the habits of regularity, temperance, moderation, foresight, and self-​command.

Interest Rightly Understood

I doubt whether men were more virtuous in aristocratic ages than in others, but they were incessantly talking of the beauties of virtue, and its utility was only studied in secret. But since the imagination takes less lofty flights, and every man’s thoughts are centered in himself, moralists are alarmed by this idea of self-​sacrifice and they no longer venture to present it to the human mind.

They therefore content themselves with inquiring whether the personal advantage of each member of the community does not consist in working for the good of all; and when they have hit upon some point on which private interest and public interest meet and amalgamate, they are eager to bring it into notice. Observations of this kind are gradually multiplied; what was only a single remark becomes a general principle, and it is held as a truth that man serves himself in serving his fellow creatures and that his private interest is to do good.

I have already shown, in several parts of this work, by what means the inhabitants of the United States almost always manage to combine their own advantage with that of their fellow citizens; my present purpose is to point out the general rule that enables them to do so. In the United States hardly anybody talks of the beauty of virtue, but they maintain that virtue is useful and prove it every day. The American moralists do not profess that men ought to sacrifice themselves for their fellow creatures because it is noble to make such sacrifices, but they boldly aver that such sacrifices are as necessary to him who imposes them upon himself as to him for whose sake they are made… .

The Americans, on the other hand, are fond of explaining almost all the actions of their lives by the principle of self-​interest rightly understood; they show with complacency how an enlightened regard for themselves constantly prompts them to assist one… .

The principle of self-​interest rightly understood is not a lofty one, but it is clear and sure. It does not aim at mighty objects, but it attains without excessive exertion all those at which it aims. As it lies within the reach of all capacities, everyone can without difficulty learn and retain it. By its admirable conformity to human weaknesses it easily obtains great dominion; nor is that dominion precarious, since the principle checks one personal interest by another, and uses, to direct the passions, the very same instrument that excites them.

The principle of self-​interest rightly understood produces no great acts of self-​sacrifice, but it suggests daily small acts of self-​denial. By itself it cannot suffice to make a man virtuous; but it disciplines a number of persons in habits of regularity, temperance, moderation, foresight, self- command; and if it does not lead men straight to virtue by the will, it gradually draws them in that direction by their habits. If the principle of interest rightly understood were to sway the whole moral world, extraordinary virtues would doubtless be more rare; but I think that gross depravity would then also be less common. The principle of interest rightly understood perhaps prevents men from rising far above the level of mankind, but a great number of other men, who were falling far below it, are caught and restrained by it. Observe some few individuals, they are lowered by it; survey mankind, they are raised.

I am not afraid to say that the principle of self-​interest rightly understood appears to me the best suited of all philosophical theories to the wants of the men of our time, and that I regard it as their chief remaining security against themselves. Towards it, therefore, the minds of the moralists of our age should turn; even should they judge it to be incomplete, it must nevertheless be adopted as necessary.

I do not think, on the whole, that there is more selfishness among us than in America; the only difference is that there it is enlightened, here it is not. Each American knows when to sacrifice some of his private interests to save the rest; we want to save everything, and often we lose it all. Everybody I see about me seems bent on teaching his contemporaries, by precept and example, that what is useful is never wrong Will nobody undertake to make them understand how what is right may be useful?

No power on earth can prevent the increasing equality of conditions from inclining the human mind to seek out what is useful or from leading every member of the community to be wrapped up in himself. It must therefore be expected that personal interest will become more than ever the principal if not the sole spring of men’s actions; but it remains to be seen how each man will understand his personal interest. If the members of a community, as they become more equal, become more ignorant and coarse, it is difficult to foresee to what pitch of stupid excesses their selfishness may lead them; and no one can foretell into what disgrace and wretchedness they would plunge themselves lest they should have to sacrifice something of their own well-​being to the prosperity of their fellow creatures.

I do not think that the system of self-​interest as it is professed in America is in all its parts self- evident, but it contains a great number of truths so evident that men, if they are only educated, cannot fail to see them. Educate, then, at any rate, for the age of implicit self-​sacrifice and instinctive virtues is already flitting far away from us, and the time is fast approaching when freedom, public peace, and social order itself will not be able to exist without education.
