Science and technology have freed humanity from many burdens and given us this new perspective and great power. This power can be used for the good of all. If wisdom governs our actions; but if the world is mad or foolish, it can destroy itself just when great advances and triumphs are almost without its grasp.

When we get to the point, as we one day will, that both sides know that in any outbreak of general hostilities, regardless of the element of surprise, destruction will be both reciprocal and complete, possibly we will have sense enough to meet at the conference table with the understanding that the era of armaments has ended and the human race must conform its actions to this truth or die.

The unleashed power of the atom has changed everything save our modes of thinking and we thus drift toward unparalleled catastrophe.

In human life, you will find players of religion until the knowledge and proficiency in religion will be cleansed from all superstitions, and will be purified and perfected by the enlightenment of real science.

A preventive war, to my mind, is an impossibility today. How could you have one if one of its features would be several cities lying in ruins, several cities where many, many thousands of people would be dead and injured and mangled, the transportation systems destroyed, sanitation implements and systems all gone?

When people speak to you about a preventive war, you tell them to go and fight it. After my experience, I have come to hate war. War settles nothing.
