We must have research for peace ... It would embrace the outstanding problems of morality. The time has come for man's intellect, his scientific method, to win over the immoral brutality and irrationality of war and militarism ... Now we are forced to eliminate from the world forever this vestige of prehistoric barbarism, this curse to the human race.

Life ... is a relationship between molecules.

Does the commandment 'Thou Shalt Not Kill' mean nothing to us? Are we to interpret it as meaning 'Thou shalt not kill except on the grand scale,' or 'Thou shalt not kill except when the national leaders say to do so'?

Science is the search for the truth--it is not a game in which one tries to beat his opponent, to do harm to others. We need to have the spirit of science in international affairs, to make the conduct of international affairs the effort to find the right solution, the just solution of international problems, and not an effort by each nation to get the better of other nations, to do harm to them when it is possible. I believe in morality, in justice, in humanitarianism.
