political arrangement, however well contrived, can guarantee peace. For such men the instruments of violence are as fearfully tempting as are, to others, the bodies of women. Of all instruments of violence, those powered by atomic energy are the most decisively destructive; and for power lovers, even under a system of world government, the temptation to resort to these all too simple and effective means for gratifying their lust will be great indeed. In view of all this, we must conclude that atomic energy is, and for a long time is likely to remain, a source of industrial power that is, politically and humanly speaking, in the highest degree undesirable.

It is not necessary in this place, nor am I competent, to enter any further into the hypothetical policy of internationally organized science. If that policy is to make a real contribution toward the maintenance of peace and the spread of political and personal liberty, it must be patterned throughout along the decentralist lines laid down in the preceding discussion of the two basic problems of food and power. Will scientists and technicians collaborate to formulate and pursue some such policy as that which has been adumbrated here?

Or will they permit themselves, as they have done only too often in the past, to become the conscious or unconscious instruments of militarists, imperialists and a ruling oligarchy of capitalistic or governmental bosses? Time alone will show. Meanwhile, it is to be hoped that all concerned will carefully consider a suggestion made by Dr. Gene Weltfish in the September, 1945, issue of the Scientific Monthly. Before embarking upon practice, all physicians swear a professional oath—the oath of Hippocrates—that they will not take improper advantage of their position, but always remember their responsibilities toward suffering humanity. Technicians and scientists, proposes Dr. Weltfish, should take a similar oath in some such words as the following: ‘I pledge myself that I will use my knowledge for the good of humanity and against the destructive forces of the world and the ruthless intent of men; and that I will work together with my fellow scientists of whatever nation, creed or colour for these our common ends.’
