that we can forsee the probable or necessary consequences of things, and are interested in them.
I hardly know how to insist on a point so plain in itself that it cannot be made plainer by any kind of reasoning. I only wish to define the sense of the general position as strictly as I can, and to guard if possible against any mistake arising from ambiguity of expression. For nothing but the certainty of absolute proof, and of having avoided every error of this sort can overcome the reluctance of the mind to admit fully and in all its consequences a distinction, which however simple in the abstract, goes to the direct subversion of one of the most deeply rooted feelings of the human mind, namely that of the essential difference between the interest we have in promoting our own welfare by all the means in our power, and that which we take in promoting the welfare of others.
