Necessity is the mistress and guide of nature. Necessity is the theme and inventress of nature, her curb and her eternal law.

Nothing in the universe is contingent, but all things are conditioned to exist and operate in a particular manner by the necessity of the divine nature.

To make a prairie it takes a clover and one bee, One clover, and a bee, And revery. The revery alone will do, If bees are few.

Two things control men’s nature, instinct and experience.

In nature we never see anything isolated, but everything in connection with something else which is before it, beside it, under it and over it.

I never saw a discontented tree. They grip the ground as though they liked it, and though fast rooted they travel about as far as we do.

Sex is a part of nature. I go along with nature.

When you go to an oasis, you go there to supply yourself with the vital things you are missing, things that you need.

Fishing is much more than fish. It is the great occasion when we may return to the fine simplicity of our forefathers.

God Almighty first planted a garden. And indeed, it is the purest of human pleasures.

Nature is not human hearted.

It’s just a job. Grass grows, birds fly, waves pound the sand. I beat people up.

Thunder is good, thunder is impressive; but it is lightning that does the work.

Studies perfect nature and are perfected still by experience.

The extreme weakness of quantum gravitational effects now poses some philosophical problems; maybe nature is trying to tell us something new here: maybe we should not try to quantize gravity.

The woods are lovely, dark and deep. But I have promises to keep, and miles to go before I sleep.

If a man walks in the woods for love of them half of each day, he is in danger of being regarded as a loafer. But if he spends his days as a speculator, shearing off those woods and making the earth bald before her time, he is deemed an industrious and enterprising citizen.

If you look deep enough you will see music; the heart of nature being everywhere music.

The career of a sage is of two kinds: He is either honored by all in the world, Like a flower waving its head, Or else he disappears into the silent forest.

I walk every day, and I look at the mountains and the fields and the small city, and I say: ‚Oh my God, what a blessing.‘ Then you realise it’s important to put it in a context beyond this woman, this man, this city, this country, this universe.

When the oak is felled the whole forest echoes with it fall, but a hundred acorns are sown in silence by an unnoticed breeze.

I give the name of cosmic sense to the more or less confused affinity that binds us psychologically to the All which envelops us. The existence of this feeling is indubitable, and apparently as old as the beginning of thought… The cosmic sense must have been born as soon as man found himself facing the forest, the sea and the stars.

I’d rather learn from one bird how to sing than teach ten thousand stars how not to dance.

I love the sea.

When California was wild, it was the floweriest part of the continent.

Time is but the stream I go a-fishing in.

The progress of rivers to the ocean is not so rapid as that of man to error.

Happy the man whose wish and care a few paternal acres bound, content to breathe his native air in his own ground.

Nature gives you the face you have at twenty; it is up to you to merit the face you have at fifty.

Trying to understand the way nature works involves a most terrible test of human reasoning ability. It involves subtle trickery, beautiful tightropes of logic on which one has to walk in order not to make a mistake in predicting what will happen. The quantum mechanical and the relativity ideas are examples of this.

To such an extent does nature delight and abound in variety that among her trees there is not one plant to be found which is exactly like another; and not only among the plants, but among the boughs, the leaves and the fruits, you will not find one which is exactly similar to another.

Occurrences in this domain are beyond the reach of exact prediction because of the variety of factors in operation, not because of any lack of order in nature.

Sponges grow in the ocean. That just kills me. I wonder how much deeper the ocean would be if that didn’t happen.

It was the Law of the Sea, they said. Civilization ends at the waterline. Beyond that, we all enter the food chain, and not always right at the top.

I shall proceed from the simple to the complex. But in war more than in any other subject we must begin by looking at the nature of the whole; for here more than elsewhere the part and the whole must always be thought of together.

Electrical science has disclosed to us the more intimate relation existing between widely different forces and phenomena and has thus led us to a more complete comprehension of Nature and its many manifestations to our senses.

The land created me. I’m wild and lonesome. Even as I travel the cities, I’m more at home in the vacant lots.

Although nature commences with reason and ends in experience it is necessary for us to do the opposite, that is to commence with experience and from this to proceed to investigate the reason.

Leave it as it is. The ages have been at work on it and man can only mar it.

Nothing on this earth is standing still. It’s either growing or it’s dying. No matter if it’s a tree or a human being.

The sun, too, shines into cesspools and is not polluted.

For in the true nature of things, if we rightly consider, every green tree is far more glorious than if it were made of gold and silver.

There are nights when the wolves are silent and only the moon howls.

Nature always wears the colors of the spirit.

Chaos was the law of nature; Order was the dream of man.

In wildness is the preservation of the world.

It appears to be a law that you cannot have a deep sympathy with both man and nature.

Nature is an infinite sphere of which the center is everywhere and the circumference nowhere.

Like music and art, love of nature is a common language that can transcend political or social boundaries.

Thaw with her gentle persuasion is more powerful than Thor with his hammer. The one melts, the other breaks into pieces.

The Constitution is the guide which I never will abandon.

I have no hostility to nature, but a child’s love to it. I expand and live in the warm day like corn and melons.

Power is my mistress. I have worked too hard at her conquest to allow anyone to take her away from me.

Nature is a mutable cloud which is always and never the same.

Never think that war, no matter how necessary, nor how justified, is not a crime.

The forests of America, however slighted by man, must have been a great delight to God; for they were the best he ever planted. The whole continent was a garden, and from the beginning, it seemed to be favored above all the other wild parks and gardens of the globe.

Money is not required to buy one necessity of the soul.

Consistency is contrary to nature, contrary to life. The only completely consistent people are dead.

O wise man! Give your wealth only to the worthy and never to others. The water of the sea received by the clouds is always sweet.

A tree’s a tree. How many more do you need to look at?

It is the nature of every person to error, but only the fool perseveres in error.
