The past is a foreign country; they do things differently there.

One of the most time-consuming things is to have an enemy.

Your worst enemy cannot harm you as much as your own thoughts, unguarded.

Nationalism is an infantile disease, the measles of mankind.

Our enemies are innovative and resourceful, and so are we. They never stop thinking about new ways to harm our country and our people, and neither do we.

The almost insoluble task is to let neither the power of others, nor our own powerlessness, stupefy us.

No nation is fit to sit in judgment upon any other nation.

Let the French but have England, and they won’t want to conquer it.

At the bottom of enmity between strangers lies indifference.

Intolerance is evidence of impotence.

If a man be gracious and courteous to strangers, it shows he is a citizen of the world, and that his heart is no island cut off from other lands, but a continent that joins to them.

This is not a clash between civilizations. It is a clash about civilization.
