Never underestimate the power of stupid people in large groups.

The love for all living creatures is the most noble attribute of man.

As long as I live, I’ll hear waterfalls and birds and winds sing. I’ll interpret the rocks, learn the language of flood, storm, and the avalanche. I’ll acquaint myself with the glaciers and wild gardens, and get as near the heart of the world as I can.

Keep your face to the sunshine and you cannot see a shadow.

Coming together is a beginning; keeping together is progress; working together is success.

The physician treats, but nature heals.

Be true to your work, your word, and your friend.

Climb the mountains and get their good tidings. Nature’s peace will flow into you as sunshine flows into trees. The winds will blow their own freshness into you, and the storms their energy, while cares will drop away from you like the leaves of Autumn.

God has cared for these trees, saved them from drought, disease, avalanches, and a thousand tempests and floods. But he cannot save them from fools.

It is horrifying that we have to fight our own government to save the environment.

To plant a garden is to believe in tomorrow.

Everybody needs beauty as well as bread, places to play in and pray in, where nature may heal and give strength to body and soul.

I went to the woods because I wished to live deliberately.

Two roads diverged in a wood and I – I took the one less traveled by, and that has made all the difference.

Birds sing after a storm; why shouldn’t people feel as free to delight in whatever remains to them?

We experience ourselves, our thoughts and feelings as something separate from the rest. A kind of optical delusion of consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us.

A true conservationist is a man who knows that the world is not given by his fathers, but borrowed from his children.

The animals of the world exist for their own reasons. They were not made for humans any more than black people were made for white, or women created for men.

The sun is but a morning star.

No man manages his affairs as well as a tree does.

To be interested in the changing seasons is a happier state of mind than to be hopelessly in love with spring.

The finest workers in stone are not copper or steel tools, but the gentle touches of air and water working at their leisure with a liberal allowance of time.

Animals are such agreeable friends – they ask no questions; they pass no criticisms.

I believe the world is incomprehensibly beautiful – an endless prospect of magic and wonder.

Our task must be to free ourselves by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty.

Turn your face to the sun and the shadows fall behind you.

Each species is a masterpiece, a creation assembled with extreme care and genius.

Every morning was a cheerful invitation to make my life of equal simplicity, and I may say innocence, with Nature herself.

We need silence to be able to touch souls.

The aspect of nature is devout. Like the figure of Jesus, she stands with bended head, and hands folded upon the breast. The happiest man is he who learns from nature the lesson of worship.

Nature arms each man with some faculty which enables him to do easily some feat impossible to any other.

Plant seeds of happiness, hope, success, and love; it will all come back to you in abundance. This is the law of nature.

Human beings are the only creatures who are able to behave irrationally in the name of reason.

All this visible world is but an imperceptible point in the ample bosom of nature.

Only two things are infinite, the universe and human stupidity, and I’m not sure about the former.
