One goes to Nature only for hints and half-truths. Her facts are crude until you have absorbed them or translated them ... It is not so much what we see as what the thing seen suggests.

A man’s life may stagnate as literally as water may stagnate, and just as motion and direction are the remedy for one, so purpose and activity are the remedy for the other.

We can outrun the wind and the storm, but we cannot outrun the demon of hurry.

The fuel in the earth will be exhausted in a thousand or more years, and its mineral wealth, but man will find substitutes for these in the winds, the waves, the sun's heat, and so forth.

Look up at the miracle of the falling snow,—the air a dizzy maze of whirling, eddying flakes, noiselessly transforming the world, the exquisite crystals dropping in ditch and gutter, and disguising in the same suit of spotless livery all objects upon which they fall.

Every walk to the woods is a religious rite, every bath in the stream is a saving ordinance. Communion service is at all hours, and the bread and wine are from the heart and marrow of Mother Earth. There are no heretics in Nature's church; all are believers, all are communicants. The beauty of natural religion is that you have it all the time; you do not have to seek it afar off in myths and legends, in catacombs, in garbled texts, in miracles of dead saints or wine-bibbing friars. It is of today; it is now and here; it is everywhere.

The Universe is a pretty big place... And the one thing I know about nature is it hates to waste anything. So I guess I'd say if it is just us, an awful lot of space is going to waste. The earth is not alone, it is not like a single apple on a tree; there are many apples on the tree, and there are many trees in the orchard.
