When you look closely it is a question whether that which is a wrong to the present community may not prove to have been a right to the interests of posterity. That sounds a little foggy; but I will make my meaning more clear when I say that I think right and wrong are both tools which are being wielded by those great hands which are shaping the destinies of the universe, that both are making for improvement; but that the action of the one is immediate, and that of the other more slow, but none the less certain. Our own distinction of right and wrong is founded too much upon the immediate convenience of the community, and does not inquire sufficiently deeply into the ultimate effect.
