The most dangerous man on earth is the man who has reckoned with his own death. All men die; few men ever really live. Sure, you can create a safe life for yourself ... and end your days in a rest home babbling on about some forgotten misfortune. I'd rather go down swinging. Besides, the less we are trying to "save ourselves," the more effective a warrior we will be. Listen to G. K. Chesterton on courage:
Courage is almost a contradiction in terms. It means a strong desire to live taking the form of a readiness to die. "He that will lose his life, the same shall save it" is not a piece of mysticism for saints and heroes. It is a piece of everyday advice for sailors or mountaineers. It might be printed in an Alpine guide or a drill book. The paradox is the whole principle of courage; even of quite earthly or quite brutal courage. A man cut off by the sea may save his life if he will risk it on the precipice. He can only get away from death by continually stepping within an inch of it. A soldier surrounded by enemies, if he is to cut his way out, needs to combine a strong desire for living with a strange carelessness about dying. He must not merely cling to life, for then he will be a coward, and will not escape. He must not merely wait for death, for then he will be a suicide, and will not escape. He must seek his life in a spirit of furious indifference to it; he must desire life like water and yet drink death like wine.
