Courage is the greatest virtue because it guarantees all the rest.

Without courage all other virtues lose their meaning.

Joan was a being so uplifted from the ordinary run of mankind that she finds no equal in a thousand years. She embodied the natural goodness and valour of the human race in unexampled perfection. Unconquerable courage, infinite compassion, the virtue of the simple, the wisdom of the just, shone forth in her. She glorifies as she freed the soil from which she sprang.

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

Courage isn't having the strength to go on - it is going on when you don't have strength.

A general of ordinary talent, occupying a bad position and surprised by a superior force, seeks his safety in retreat; but a great captain supplies all deficiencies by his courage, and marches boldly to meet the attack. By this means he disconcerts his adversary, and if this last shows any irresolution in his movements, a skilful leader, profiting by his indecision, may even hope for victory.
