The root of humanly caused evil is not man's animal nature, not territorial aggression, or innate selfishness, but our need to gain self-esteem, deny our mortality, and achieve a heroic self-image. Our desire for the best is the cause of the worst.

If some incarnation of evil as unambiguous as Hitler appeared again, I would have no moral qualms about killing the enemy. But in the modern world of moral murkiness, I prefer to keep my hands as clean of enemy blood as possible.

Throughout my life, I've had different metaphors for freedom. At one time, it was skin diving. In the ocean you feel weightless; you escape from gravity.

The lover heals the world not by a vague and abstract love for everybody and everything, but by becoming passionate and vowing fidelity to concrete relationships, persons, institutions, and places.

We all yearn to fly. We are creatures of longing. We do not need to [physically fly] to be airborne. What I call the aerial instinct-the drive to transcend our present condition- is the defining characteristic of a human being. We are restless animals, eternal travelers who are forever in the process of becoming. Consciousness itself is a flight from the here and now to the beyond. Our reach always exceeds our grasp, which is what Heaven is for.
