Ultimately there is no power to narcissistic, self-indulgent thinking. Authentic thinking originates with an encounter with the world. - Abraham Joshua Heschel

The opposite of freedom is not determinism, but hardness of heart. Freedom presupposes openness of heart, of mind, of eye and ear.

There are dead thoughts and there are living thoughts. A dead thought has been compared to a stone which one may plant in the soil. Nothing will come out. A living thought is like a seed. In the process of thinking, an answer without a question is devoid of life. It may enter the mind; it will not penetrate the soul. It may become a part of one’s knowledge; it will not come forth as a creative force.

The sense of meaning is not born in ease and sloth. It comes after bitter trials, disappointments in the glitters, foundering, strandings. It is the marrow from the bone. There is no manna in our wilderness. Thought is not bred apart from experience or from inner surroundings. Thinking is living, and no thought is bred in an isolated cell in the brain. No thought is an island.
