If we do not permit the earth to produce beauty and joy, it will in the end not produce food, either.

The snow itself is lonely or, if you prefer, self-sufficient. There is no other time when the whole world seems composed of one thing and one thing only.

When a man wantonly destroys one of the works of man we call him a vandal. When he destroys one of the works of god we call him a sportsman.

We have not merely escaped from something but into something... We have joined the greatest of all communities, which is not that of man alone but of everything which shares with us the great adventure of being alive.

Nature, in her blind thirst for life has filled every possible cranny of the rotting earth with some sort of fantastic creature.

An abundance of some good things is perfectly compatible with the scarcity of others; that life is everywhere precarious, man everywhere small.

To those who study her, Nature reveals herself as extraordinarily fertile and ingenious in devising means, but she has no ends which the human mind has been able to discover or comprehend.
