Learn to reverence night and to put away the vulgar fear of it, for, with the banishment of night from the experience of man, there vanishes as well a religious emotion, a poetic mood, which gives depth to the adventure of humanity.

Poetry is as necessary to comprehension as science. It is as impossible to live without reverence as it is without joy.

Wolves are not our brothers; they are not our subordinates, either. They are another nation, caught up just like us in the complex web of time and life.

As well expect Nature to answer your human values as to come into your house and sit in a chair.

The adventure of the sun is the greatest natural drama by which we live.

We of the age of the machines, having delivered ourselves of nocturnal enemies, now have a dislike of night itself. With lights and ever more lights, we drive the holiness and beauty of night back to the forests and the sea.

It is only when we are aware of the earth and of the earth as poetry that we truly live.
