I intend to leave after my death a large fund for the promotion of the peace idea, but I am skeptical as to its results.

One can state, without exaggeration, that the observation of and the search for similarities and differences are the basis of all human knowledge.

I have not the slightest pretension to call my verses poetry; I write now and then for no other purpose than to relieve depression or to improve my English.

Good wishes alone will not ensure peace.

Justice is to be found only in imagination.
