  "Your errors of the past make your relation to others difficult when the present shows you that you might repeat them."

Dag Hammarskjöld, "Markings", p. 113

 "(...) without the humility and warmth which you have to develop in your relations to the few with whom you are personally involved, you will never be able to do anything for the many. Without them, you will live in a world of abstractions, where your solipsism, your greed for power, and your death-wish lack the one opponent which is stronger than they — love."
