There are three principles in a man's being and life, the principle of thought, the principle of speech, and the principle of action. The origin of all conflict between me and my fellow-men is that I do not say what I mean and I don't do what I say.
Martin BuberIn spite of all similarities, every living situation has, like a newborn child, a new face, that has never been before and will never come again. It demands of you a reaction that cannot be prepared beforehand. It demands nothing of what is past. It demands presence, responsibility; it demands you.
Martin Buber
