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.
–Alexis de Tocqueville, Democracy in America, Book II, Chapter 8
