Henry David Thoreau on nature

I have learned, that if one advances confidently in the direction of his dreams, and endeavors to live the life he has imagined, he will meet with a success unexpected in common hours.

To be a philosopher is not merely to have subtle thoughts; but so to love wisdom as to live according to its dictates.

We must walk consciously only part way toward our goal, and then leap in the dark to our success.

Every day, man is making bigger and better fool-proof things, and every day, nature is making bigger and better fools. So far, I think nature is winning.

Albert Einstein1879–1955

Nature does nothing uselessly.

Aristotle384–322 BCPolitics, Book I, 1253a.8

Nature scarcely ever gives us the very best; for that we must have recourse to art.
