We patronize the animals for their incompleteness, for their tragic fate of having taken form so far below ourselves. And therein we err, and greatly err. For the animal shall not be measured by man. In a world older and more complete than ours, they are more finished and complete, gifted with extensions of the senses we have lost or never attained, living by voices we shall never hear. They are not brethren, they are not underlings; they are other Nations, caught with ourselves in the net of life and time.

When the Pleiades and the wind in the grass are no longer a part of the human spirit, a part of very flesh and bone, man becomes, as it were, a kind of cosmic outlaw, having neither the completeness nor integrity of the animal nor the birthright of a true humanity.

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

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

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

The seas are the heart's blood of the earth.

If there is one thing clear about the centuries dominated by the factory and the wheel, it is that although the machine can make everything from a spoon to a landing-craft, a natural joy in earthly living is something it never has and never will be able to manufacture.
