Do no dishonor to the earth lest you dishonor the spirit of man.

The adventure of the sun is the great natural drama by which we live, and not to have joy in it and awe of it, not to share in it, is to close a dull door on nature's sustaining and poetic spirit.

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.

The animal should not be measured by man. In a world older than ours they move finished and complete, gifted with extensions of the sense we have lost or never attained, living by voices we shall never hear.

Touch the earth, love the earth, honour the earth, her plains, her valleys, her hills, and her seas; rest your spirit in her solitary places.

Into every empty corner, into all forgotten things and nooks, nature struggles to pour life, pouring life into the dead, life into life itself.

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