Of all the virtues, courage is certainly the most universally admired.
Courage can serve for everything, for good as well as for evil, and cannot change the nature of these.
Courage is not the absence of fear, but the capacity to overcome fear, thanks to a stronger and more generous will. It is not a piece of knowledge, but a decision. It is not an opinion, but an act, because reason is not enough and is not sufficient to act or to want.
It takes courage to think, because no one can do it in our place, but also to suffer or to fight, to endure or to endure, to defend or to fight, to live and to die.
