Conscience is the root of all true courage if a man would be brave let him obey his conscience.

I always disliked dogs, those protectors of cowards who lack the courage to fight an assailant themselves.

You cannot build character and courage by destroying men's initiative and independence.

We are biological creatures. We are born, we live, we die. There is no transcendent purpose to existence. At best we are creatures of reason, and by using reason we can cure ourselves of emotional excess. Purged of both hope and fear, we find courage in the face of helplessness, insignificance and uncertainty.

Courage is the art of being the only one who knows you're scared to death.
