I believe that there is a greater power in the world than the evil power of military force, of nuclear bombs -- there is the power of good, of morality, of humanitarianism.

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.

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.

I made use of the college library by borrowing books other than scientific books, such as all of the plays by George Bernard Shaw, the writing of Edgar Allan Poe. The college library helped me to develop a broader aspect on life.

Although physicians, as part of their training, are taught that the dosage of a drug that is prescribed for the patient must be very carefully determined and controlled, they seem to have difficulty in remembering that the same principle applies to the vitamins.

We may, I believe, anticipate that the chemist of the future who is interested in the structure of proteins, nucleic acids, polysaccharides, and other complex substances with high molecular weight will come to rely upon a new structural chemistry, involving precise geometrical relationships among the atoms in the molecules and the rigorous application of the new structural principles, and that great progress will be made, through this technique, in the attack, by chemical methods, on the problems of biology and medicine.

I think that the formation of [DNA's] structure by Watson and Crick may turn out to be the greatest developments in the field of molecular genetics in recent years.
