War never solves anything

Tanks and planes cannot redeem humanity. A man with a gun is like a beast without a gun. The killing of snakes will save us for the moment but not forever. The war will outlast the victory of arms if we fail to conquer the infamy of the soul: the indifference to crime, when committed against others. For evil is indivisible. It is the same in thought and in speech, in private and in social life. The greatest task of our time is to take the souls of men out of the pit. The world has experienced that God is involved. Let us forever remember that the sense for the sacred is as vital to us as the light of the sun. There can be no nature without spirit, no world without the Torah, no brotherhood without a father, no humanity without God.—Abraham Joshua Heschel in Moral Grandeur and Spiritual Audacity: Essays, 211
