Selfishness is not living as one wishes to live, it is asking others to live as one wishes to live. And unselfishness is letting other people's lives alone, not interfering with them. Selfishness always aims at creating around it an absolute uniformity of type. Unselfishness recognizes infinite variety of type as a delightful thing, accepts it, acquiesces in it, enjoys it. It is not selfish to think for oneself. A man who does not think for himself does not think at all. It is grossly selfish to require of one's neighbor that he should think in the same way, and hold the same opinions. Why should he?
