Of all the unexpected qualities of an unexpected universe, the sheer organizing power of animal and plant metabolism is one of the most remarkable. . . . Where it reaches its highest development, in the human mind, we forget it completely. . . . So important does nature regard this unseen combustion . . . that a starving man's brain will be protected to the last while his body is steadily consumed.

It is surely one of the curious paradoxes of history that science which professionally has little to do with faith, owes its origins to an act of faith that the universe can be rationally interpreted, and that science today is sustained by that assumption.

To have dragons one must have change; that is the first principle of dragon lore.

Man is always marveling at what he has blown apart, never at what the universe has put together, and this is his limitation.

Great minds have always seen it. That is why man has survived his journey this long. When we fail to wish any longer to be otherwise than what we are, we will have ceased to evolve. Evolution has to be lived forward. I say this as one who has stood above the bones of much that has vanished, and at midnight has examined his own face.

Though men in the mass forget the origins of their need, they still bring wolfhounds into city apartments, where dog and man both sit brooding in wistful discomfort. The magic that gleams an instant between Argos and Odysseus is both the recognition of diversity and the need for affection across the illusions of form. It is nature's cry to homeless, far-wandering, insatiable man: "Do not forget your brethren, nor the green wood from which you sprang. To do so is to invite disaster.

Certainly science has moved forward. But when science progresses, it often opens vaster mysteries to our gaze. Moreover, science frequently discovers that it must abandon or modify what it once believed. Sometimes it ends by accepting what it has previously scorned.
