with far the greatest part of mankind, interest is the governing principle; and that, almost, every man is more or less, under its influence. Motives of public virtue may for a time, or in particular instances, actuate men to the observance of a conduct purely disinterested; but they are not of themselves sufficient to produce a persevering conformity to the refined dictates and obligations of social duty. Few men are capable of making a continual sacrifice of all views of private interest, or advantage, to the common good.
