The human race has reached a turning point. Man has opened the secrets of nature and mastered new powers. If he uses them wisely, he can reach new heights of civilization. If he uses them foolishly, they may destroy him. Man must create the moral and legal framework for the world which will insure that his new powers are used for good and not for evil.

At the present moment in world history nearly every nation must choose between alternative ways of life. The choice is too often not a free one.

If there is one basic element in our Constitution, it is civilian control of the military.

Being a president is like riding a tiger. A man has to keep on riding or he is swallowed.

Within the first few months I discovered that being president is like riding a tiger. A man has to keep riding or be swallowed. The fantastically crowded nine months of 1945 taught me that a President either is constantly on top of events or, if he hesitates, events will soon be on top of him. I never felt I could let up for a single moment.
