Nature cannot be bribed, it acts with no regard for human wishes or desires.

We need places to scream and run wild as well as places to be quiet.

Nature gives us roses and viruses, earthquakes and moonlight, while being totally indifferent to our joys and pain.

The squirrels, leaping joyfully from branch to branch: not a single one doubts its existence.

It is as natural to feel free as it is to feel hungry and thirsty.

Everything you see, hear, touch, think, dream is nature. Nature is everything.

There is only one true thing: the world as it stands before you.

Nature is reality; everything else is fiction.

I can't think indoors. I have to see the sky or I'm lost.
