Are we not ourselves nature, nature without end?

In tampering with the earth, we tamper with a mystery.

Oil! Our secret god, our secret sharer, our magic wand, fulfiller of our every desire, our coconspirator, the sine qua non in all we do!

It is the little causes, long continued, which are considered as bringing about the greatest changes of the earth.

The earth is our existence, and our body is attached to the earth.

There is a time to battle against nature, and a time to obey her. True wisdom lies in making the right choice.

Nature never jests.

Men have an extraordinarily erroneous opinion of their position in nature; and the error is ineradicable.

The oldest voice in the world is the wind.

It raineth every day, and the weather represents our tearful despair on a large scale.

When nature is overriden, she takes her revenge.

A world is sooner destroyed than made.

We have forgotten how to be good guests, how to walk lightly on the earth as its other creatures do.
