Observe always that everything is the result of a change, and get used to thinking that there is nothing Nature loves so well as to change existing forms and to make new ones like them.
Where am I, or what? From what causes do I derive my existence, and to what condition shall I return? ... I am confounded with all these questions, and begin to fancy myself in the most deplorable condition imaginable, environed with the deepest darkness, and utterly deprived of the use of every member and faculty.
Most fortunately it happens, that since Reason is incapable of dispelling these clouds, Nature herself suffices to that purpose, and cures me of this philosophical melancholy and delirium, either by relaxing this bent of mind, or by some avocation, and lively impression of my senses, which obliterate all these chimeras. I dine, I play a game of backgammon, I converse, and am merry with my friends. And when, after three or four hours' amusement, I would return to these speculations, they appear so cold, and strained, and ridiculous, that I cannot find in my heart to enter into them any farther.
Men speak of natural rights, but I challenge any one to show where in nature any rights existed or were recognized until there was established for their declaration and protection a duly promulgated body of corresponding laws.
It is not enough to fight for the land; it is even more important to enjoy it. While you can. While it's still here. So get out there and hunt and fish and mess around with your friends, ramble out yonder and explore the forests, climb the mountains, bag the peaks, run the rivers, breathe deep of that yet sweet and lucid air, sit quietly for a while and contemplate the precious stillness, the lovely, mysterious, and awesome space.
Enjoy yourselves, keep your brain in your head and your head firmly attached to the body, the body active and alive, and I promise you this much; I promise you this one sweet victory over our enemies, over those desk-bound men and women with their hearts in a safe deposit box, and their eyes hypnotized by desk calculators. I promise you this; You will outlive the bastards.
Nothing goes unrecorded. Every word of leaf and snowflake and particle of dew . . . as well as earthquake and avalanche, is written down in Nature's book.
To explain all nature is too difficult a task for any one man or even for any one age. Tis much better to do a little with certainty & leave the rest for others that come after than to explain all things by conjecture without making sure of any thing.
When I go biking, I repeat a mantra of the day's sensations: bright sun, blue sky, warm breeze, blue jay's call, ice melting and so on. This helps me transcend the traffic, ignore the clamorings of work, leave all the mind theaters behind and focus on nature instead. I still must abide by the rules of the road, of biking, of gravity. But I am mentally far away from civilization.
A quiet secluded life in the country, with the possibility of being useful to people to whom it is easy to do good, and who are not accustomed to have it done to them; then work which one hopes may be of some use; then rest, nature, books, music, love for one's neighbor -- such is my idea of happiness.
In those vernal seasons of the year, when the air is calm and pleasant, it were an injury and a sullenness against Nature not to go out and see her riches, and partake in her rejoicing with heaven and earth. - John Milton
To those who do not know mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty of nature. . . . If you want to learn about nature, to appreciate nature, it is necessary to understand the language that she speaks in.
That man is more of a political animal than bees or any other gregarious animals is evident. Nature, as we often say, makes nothing in vain, and man is the only animal whom she has endowed with the gift of speech.
Nature is always consistent, though she feigns to contravene her own laws. She keeps her laws, and seems to transcend them. She arms and equips an animal to find its place and living in the earth, and at the same time she arms and equips another animal to destroy it.
Animals in nature, contrary to the suspicions of cynics or the hopes of idealists, are neither intrinsically vicious nor altruistic. Competition and cooperation are both nature's ways.
. . . birds will appeal most strongly to us through their songs. When your ears are attuned to the music of birds, your world will be transformed. Birds' songs are the most eloquent of Natures' voices.
Bring out the nature of the materials, let their nature intimately into your scheme. . .Reveal the nature of the wood, plaster, brick or stone in your designs: they are all by nature friendly and beautiful.
I am among those who think that science has great beauty. . .a scientist in his laboratory is not only a technician but also a child placed in front of natural phenomena which impresses him like a fairy tale.
Even though the genius of man might make various inventions, attaining the same end by various means, it will not invent anything more beautiful, or more economical, or more direct than nature, for in nature's inventions nothing is wanting and nothing is superfluous.
The profession I'm part of has, as its whole purpose, the rendering of the physical world understandable and beautiful. Without this you have only tables and statistics.
It is a great mortification to the vanity of man that his utmost art and industry can never equal the meanest of Nature's productions, either for beauty or value. Art is only the underworkman, and is employed to give a few strokes of embellishment to those pieces which come from the hand of the master.
He that had never seen a river imagined the first he met with to be the sea; and the greatest things that have fallen within our knowledge we conclude the extremes that nature makes of the kind.
Nature has presented us with a large faculty of entertaining ourselves alone, and often calls us to it, to teach us that we owe ourselves in part to society, but chiefly and mostly to ourselves.
The most beautiful thing we can experience is the Mysterious -- the knowledge of the existence of something unfathomable to us, the manifestation of the most profound reason coupled with the most brilliant beauty. I cannot imagine a God who rewards and punishes the objects of his creation, or who has a will of the kind we experience in ourselves. I am satisfied with the mystery of life's eternity and with the awareness of -- and glimpse into -- the marvelous construction of the existing world together with the steadfast determination to comprehend a portion, be it ever so tiny, of the reason that manifests itself in nature.
I roamed the countryside searching for the answers to things I did not understand. Why shells existed on the tops of mountains along with the imprints of coral and plant and seaweed usually found in the sea. Why the thunder lasts a longer time than that which causes it and why immediately on its creation the lightning becomes visible to the eye while thunder requires time to travel. How the various circles of water form around the spot which has been struck by a stone and why a bird sustains itself in the air. These questions and other strange phenomena engaged my thought throughout my life.
Thus, from the war of nature, from famine and death, the most exalted object which we are capable of conceiving, namely, the production of the higher animals, directly follows. There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.
I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, to discover that I had not lived.
