• 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.
