Honest history is the weapon of freedom.

There is no more dangerous thing for a democracy than a foreign policy based on presidential preventive war.

Man generally is entangled in insoluble problems; history is consequently a tragedy in which we are all involved, whose keynote is anxiety and frustration, not progress and fulfilment.

Problems will always torment us because all important problems are insoluble: that is why they are important. The good comes from the continuing struggle to try and solve them, not from the vain hope of their solution.

If we are to survive, we must have ideas, vision, and courage. These things are rarely produced by committees. Everything that matters in our intellectual and moral life begins with an individual confronting his own mind and conscience in a room by himself.

Every President reconstructs the Presidency to meet his own psychological needs.

History is, indeed, an argument without end.
