“Swords, Lances, arrows, machine guns, and even high explosives have had far less power over the fates of nations than the typhus louse, the plague flea, and the yellow-fever mosquito. Civilizations have retreated from the plasmodium of malaria, and armies have crumbled into rabbles under the onslaught of cholera spirilla, or of dysentery and typhoid bacilli. Huge areas have bee devastated by the trypanosome that travels on the wings of the tsetse fly, and generations have been harassed by the syphilis of a courtier. War and conquest and that herd existence which is an accompaniment of what we call civilization have merely set the stage for these more powerful agents of human tragedy.”

“Infectious disease is one of the great tragedies of living things - the struggle for existence between two different forms of life... Incessantly, the pitiless war goes on, without quarter or armistice - a nationalism of species against species.”

“Political realism refuses to identify the moral aspirations of a particular nation with the moral laws that govern the universe. As it distinguishes between truth and opinion, so it distinguishes between truth and idolatry. All nations are tempted — and few have been able to resist the power for long — to clothe their own aspirations and action in the moral purposes of the universe. To know that nations are subject to the moral law is one thing, while to pretend to know with certainty what is good and evil in the relations among nations is quite another. There is a world of difference between the belief that all nations stand under the judgment of God, inscrutable to the human mind, and the blasphemous conviction that God is always on one's side and that what one wills oneself cannot fail to be willed by God also.The lighthearted equation between a particular nationalism and the counsels of Providence is morally indefensible, for it is that very sin of pride against which the Greek tragedians and the Biblical prophets have warned rulers and ruled. That equation is also politically pernicious, for it is liable to engender the distortion in judgment which, in the blindness of crusading frenzy, destroys nations and civilizations - in the name of moral principle, ideal, or God himself.”

“We have a historical chance. Imagine the power which Egypt, Iran, and Turkey have, are working in one organization. We have the world's energy center, manpower, history and civilization. If this confederate has created, it will regain the face of nation.”

“But shouldn't all of us on earth give the best we have to others and offer whatever is in our power?”

“It's high time that Christians made up their minds to do something . . . What are we going to show in the way of resistance-as compared to the Communists, for instance-when all this terror is over? We will be standing empty-handed. We will have no answer when we are asked: What did you do about it? ”

“The struggle for power is universal in time and space and is an undeniable fact of experience. It cannot be denied that throughout historic time, regardless of social, economic and political conditions, states have met each other in contests for power. Even though anthropologists have shown that certain primitive peoples seem to be free from the desire for power, nobody has yet shown how their state of mind can be re-created on a worldwide scale so as to eliminate the struggle for power from the international scene. … International politics, like all politics, is a struggle for power. Whatever the ultimate aims of international politics, power is always the immediate aim.”
