Courage is the human virtue that counts most-courage to act on limited knowledge and insufficient evidence. That's all any of us have.

We Americans of today, together with our allies, are passing through a period of supreme test. It is a test of our courage - of our resolve - of our wisdom - our essential democracy.

Life at its noblest leaves mere happiness far behind; and indeed cannot endure it. Happiness is not the object of life: life has no object: it is an end in itself; and courage consists in the readiness to sacrifice happiness for an intenser quality of life.

Courage is an inner resolution to go forward despite obstacles.
