"For men love one another with a spiritual love only when they have suffered the same sorrow together, when through long days they have ploughed the stony ground bowed beneath the common yoke of a common grief. It is then that they know one another and feel one another, and feel with one another. In their common anguish, they pity one another and they love one another. For to love goes with pity and if bodies are united by pleasure, souls are united by pain."
