Why is it that when political ammunition runs low, inevitably the rusty artillery of abuse is always wheeled into action?

I have been told that one of the reasons the astronomers of the world cooperate is the fact that there is no one nation from which the entire sphere of the sky can be seen. Perhaps there is in that fact a parable for national statesmen, whose political horizons are all too often limited by national horizons.

If we value the pursuit of knowledge, we must be free to follow wherever that search may lead us. The free mind is no barking dog to be tethered on a ten-foot chain.

The tragedy of our day is the climate of fear in which we live, and fear breeds repression. Too often sinister threats to the bill of rights, to freedom of the mind, are concealed under the patriotic cloak, of anti-communism.

Carelessness about our security is dangerous, carelessness about our freedom is also dangerous.

Our strength lies, not alone in our proving grounds and our stockpiles, but in our ideals, our goals, and their universal appeal to all men who are struggling to breathe free.

Self-Criticism is the secret weapon of democracy, and candor and confession are good for the political soul.
