Two different sets of philosophers have attempted to teach us this hardest of all the lessons of morality. One set have laboured to increase our sensibility to the interests of others; another, to diminish that to our own. The first would have us feel for others as we naturally feel for ourselves. The second would have us feel for ourselves as we naturally feel for others. Both, perhaps, have carried their doctrines a good deal beyond the just standard of nature and propriety.
