The frightening nature of knowledge leaves one no alternative but to become a warrior.
BEYOND GOOD AND EVIL
War and Warriors
By our best enemies we do not want to be spared, nor by those either whom we love from the very heart. So let me tell you the truth!
I know the hatred and envy of your hearts. Ye are not great enough not to know of hatred and envy. Then be great enough not to be ashamed of them!
And if ye cannot be saints of knowledge, then, I pray you, be at least its warriors. They are the companions and forerunners of such saintship.
I see many soldiers; could I but see many warriors! “Uniform” one calleth what they wear; may it not be uniform what they therewith hide!
One can only be silent and sit peacefully when one hath arrow and bow; otherwise one prateth and quarrelleth. Let your peace be a victory!
War and courage have done more great things than charity. Not your sympathy, but your bravery hath hitherto saved the victims.
Ye shall only have enemies to be hated, but not enemies to be despised. Ye must be proud of your enemies; then, the successes of your enemies are also your successes.
Resistance—that is the distinction of the slave. Let your distinction be obedience. Let your commanding itself be obeying!
To the good warrior soundeth “thou shalt” pleasanter than “I will.” And all that is dear unto you, ye shall first have it commanded unto you.
Let your love to life be love to your highest hope; and let your highest hope be the highest thought of life!
Your highest thought, however, ye shall have it commanded unto you by me—and it is this: man is something that is to be surpassed.
So live your life of obedience and of war! What matter about long life! What warrior wisheth to be spared!
I spare you not, I love you from my very heart, my brethren in war!—
Thus spoke Zarathustra.
He who fights with monsters should be careful lest he thereby become a monster.
AND IF THOU GAZE LONG INTO AN ABYSS, THE ABYSS WILL ALSO GAZE INTO THEE. (Nietzsche)

We can easily forgive a child who is afraid of the dark;
THE REAL TRAGEDY OF LIFE IS WHEN MEN ARE AFRAID OF THE LIGHT. (Plato)
