So high do these plants stand in the favour of the Chinese gardener, that he will cultivate them extensively, even against the wishes of his employer; and, in many instances, rather leave his situation than give up the growth of his favourite flower.

The attention of a traveller, should be particularly turned, in the first place, to the various works of Nature, to mark the distinctions of the climates he may explore, and to offer such useful observations on the different productions as may occur.

As a scientist I cannot help feeling that all religions are on a tottering foundation. None is perfect or inspired. As for their prophets, there are as many today as ever before, only now science refuses to let them overstep the bounds of common sense.

The harvest moon has no innocence, like the slim quarter moon of a spring twilight, nor has it the silver penny brilliance of the moon that looks down upon the resorts of summer time. Wise, ripe, and portly, like an old Bacchus, it waxes night after night.

As a scientist, I can not help feeling that all religions are on a tottering foundation. None is perfect or inspired.The idea that a good God would send people to a burning hell is utterly damnable to me. I don't want to have anything to do with such a God.

In the gametes of an individual hybrid the Anlagen for each individual parental character are found in all possible combinations but never in a single gamete the Anlagen for a pair of characters. Each combination occurs with approximately the same frequency.

Fragments of the natural method must be sought with the greatest care. This is the first and last desideratum among botanists. Nature makes no jumps. [Natura non facit saltus] All taxa show relationships on all sides like the countries on a map of the world.

The wilderness is a place of rest - not in the sense of being motionless, for the lure, after all, is to move, to round the next bend. The rest comes in the isolation from distractions, in the slowing of the daily centrifugal forces that keep us off balance.

There are as many species as the infinite being created diverse forms in the beginning, which, following the laws of generation, produced many others, but always similar to them: therefore there are as many species as we have different structures before us today.

A disease which new and obscure to you, Doctor, will be known only after death; and even then not without an autopsy will you examine it with exacting pains. But rare are those among the extremely busy clinicians who are willing or capable of doing this correctly.

Extension work is not exhortation. Nor is it exploitation of the people, or advertising of an institution, or publicity work for securing students. It is a plain, earnest, and continuous effort to meet the needs of the people on their own farms and in the localities.

This drink has a magical power. It strengthens the weak, and revives those who have fainted. Those tired after work and physical activity can return their life forces by this drink much sooner than by nourishment. ... It works as a diuretic, an appetizer, an antitoxin.

We may take it to be the accepted idea that the Mosaic books were not handed down to us for our instruction in scientific knowledge, and that it is our duty to ground our scientific beliefs upon observation and inference, unmixed with considerations of a different order.

Wilderness has been characterized as barren and unproductive; little can be grown in its sand and rock. But the crops of wilderness have always been its spiritual values - silence and solitude, a sense of awe and gratitude - able to be harvested by any traveler who visits.

The best opinion now is, that there are multitudinous forms which are not sufficiently differentiated to be distinctively either plant or animal, while, as respects ordinary plants and animals, the difficulty of laying down a definition has become far greater than ever before.

We have really, that I know of, no philosophical basis for high and low. Moreover, the vegetable kingdom does not culminate, as the animal kingdom does. It is not a kingdom, but a common-wealth; a democracy, and therefore puzzling and unaccountable from the former point of view.

If the creatures with fur/feathers/fins are our brothers in a lower stage of development then their very weakness and inability to protest, demands that man should refrain from torturing them for the mere possibility of obtaining some knowledge which he believes may be to his own interest.

The serenity produced by the contemplation and philosophy of nature is the only remedy for prejudice, superstition, and inordinate self-importance, teaching us that we are all a part of Nature herself, strengthening the bond of sympathy which should exist between ourselves and our brother man. . .

A multitude of words doth rather obscure than illustrate, they being a burden to the memory, and the first apt to be forgotten, before we come to the last. So that he that uses many words for the explaining of any subject, doth, like the cuttle-fish, hide himself, for the most part, in his own ink.

The first step in wisdom is to know the things themselves; this notion consists in having a true idea of the objects; objects are distinguished and known by classifying them methodically and giving them appropriate names. Therefore, classification and name-giving will be the foundation of our science.

I have often started off on a walk in the state called mad-mad in the sense of sore-headed, or mad with tedium or confusion; I have set forth dull, null and even thoroughly discouraged. But I never came back in such a frame of mind, and I never met a human being whose humor was not the better for a walk.

There are always some of us, not a few, in every generation, who go over wholly to the green flag. It is such a passionless fealty, so reticent a love, that neither do trumpets sound for it nor quarrels arise from it. Only, you will find that those who have pledged allegiance are happy about it in quiet.

Let us read the Bible without the ill-fitting colored spectacles of theology, just as we read other books, using our own judgment and reason, listening to the voice within, not to the noisy babel without. Most of us possess discriminating reasoning powers. Can we use them or must we be fed by others like babes?

This constitution we designate by the word genotype. The word is entirely independent of any hypothesis; it is fact, not hypothesis that different zygotes arising by fertilisation can thereby have different qualities, that, even under quite similar conditions of life, phenotypically diverse individuals can develop.

From my earliest childhood I nourished and cherished the desire to make a creditable journey in a new country, and write such a respectable account of its natural history as should give me a niche amongst the scientific explorers of the globe I inhabit, and hand my name down as a useful contributor of original matter.

If delight may provoke men's labour, what greater delights is there then to behold the earth as apparelled with plants, as with a robe of imbroidered worke, set with orient pearles, and garnished with great diversitie of rare and costly jewels? The delight is great but the use greater, and joyned often with necessitie.

And to think of this great country in danger of being dominated by people ignorant enough to take a few ancient Babylonian legends as the canons of modern culture. Our scientific men are paying for their failure to speak out earlier. There is no use now talking evolution to these people. Their ears are stuffed with Genesis.

Several of my young acquaintances are in their graves who gave promise of making happy and useful citizens and there is no question whatever that cigarettes alone were the cause of their destruction. No boy living would commence the use of cigarettes if he knew what a useless, soulless, worthless thing they would make of him.

Although I went to college as a youth, I never considered it necessary to steep oneself in academic learning, in order to learn how to think. I welcome a fair and square, open and above-board fight on any subject, including this, but I despise a man who sneaks around under a cloak or cover of any society or clique to strike his blows.

...the need for a garden of rare palms and vines and ornamental trees and shrubs which would be near enough to a growing city to form a quiet place where children with their elders could peer, as it were, into those fascinating jungles and palm glades of the tropics which have for generations stimulated the imaginations of American youth.

My personal credo as a libertarian conservative: I think all attempts to reform your fellow-citizens or tell them how to live their lives are arrogant and tyrannical. THAT'S why I oppose Leftism. I want people to be free to manage their own lives. Reform is just authoritarianism. People are not playthings for anybody's theories or obsessions.

Religion grows with the intelligence of man, but all religions of the past and probably all of the future will sooner or later become petrified forms instead of living helps to mankind. Until that time comes, however, if religion of any name or nature makes man more happy, comfortable, and able to live peaceably with his brothers, it is good.

I thought that I had found something new. But then I convinced myself that the Abbot Gregor Mendel in Brünn, had, during the sixties, not only obtained the same result through extensive experiments with peas, which lasted for many years, as did de Vries and I, but had also given exactly the same explanation, as far as that was possible in 1866.

A great teacher is not simply one who imparts knowledge to his students, but one who awakens their interest in it and makes them eager to pursue it for themselves. He is a spark plug, not a fuel pipe. The reason colleges exist is to bring students into contact with contagious personalities, for otherwise they might as well be correspondance schools.

When it's one animal, you really do have a tougher time because you've gotta commit to story structures that maybe are difficult to find the range in the animal to tell those stories. There are only so many things they do, if they're living in the natural world, that we can appreciate. There are plenty of things that they do that we don't appreciate.

The secret of improved plant breeding, apart from scientific knowledge, is love. While I was conducting experiments to make spineless cacti, I often talked to the plants. . . . "You have nothing to fear," I would tell them. "You don't need your defensive thorns. I will protect you." Gradually the useful plant of the desert emerged in a thornless variety.

As a scientist, I cannot help feeling that all religions are on a tottering foundation . . . I am an infidel today. I do not believe what had been served to me to believe. I am a doubter, a questioner, a skeptic. When it can be proved to me that there is immortality, that there is resurrection beyond the gates of death, then will I believe. Until then, no.

As the brain of man is the speck of dust in the universe that thinks, so the leaves—the fern and the needled pine and the latticed frond and the seaweed ribbon—perceive the light in a fundamental and constructive sense. … Their leaves see the light, as my eyes can never do. … They impound its stellar energy, and with that force they make life out of the elements.

Yet man does recognise himself [as an animal]. But I ask you and the whole world for a generic differentia between man and ape which conforms to the principles of natural history, I certainly know of none... If I were to call man ape or vice versa, I should bring down all the theologians on my head. But perhaps I should still do it according to the rules of science.

Plants, in a state of nature, are always warring with one another, contending for the monopoly of the soil,-the stronger ejecting the weaker,-the more vigorous overgrowing and killing the more delicate. Every modification of climate, every disturbance of the soil, every interference with the existing vegetation of an area, favours some species at the expense of others.

The theory of Reincarnation, which originated in India, has been welcomed in other countries. Without doubt, it is one of the most sensible and satisfying of all religions that mankind has conceived. This, like the others, comes from the best qualities of human nature, even if in this, as in the others, its adherents sometimes fail to carry out the principles in their lives.

All scientists have found that preconceived notions, dogmas, and all personal prejudice and bias, must be set aside, listening patiently, quietly and reverently to the lessons, one by one, which Mother Nature has to teach, shedding light on that which was before a mystery, so that all who will may see and know. She conveys her truths only to those who are passive and receptive.

Those who would legislate against the teaching of evolution should also legislate against gravity, electricity and the unreasonable velocity of light, and also, should introduce a clause to prevent the use of the telescope, the microscope and the spectroscope or any other instrument of precision which may in the future be invented, constructed or used for the discovery of truth.

The human mind prefers something which it can recognize to something for which it has no name, and, whereas thousands of persons carry field glasses to bring horses, ships, or steeples close to them, only a few carry even the simplest pocket microscope. Yet a small microscope will reveal wonders a thousand times more thrilling than anything which Alice saw behind the looking-glass.

A thing is either alive or it isn’t; there is nothing that is almost alive. There is but the remotest possibility of the origin of life by spontaneous generation, and every likelihood that Arrhenius is right when he dares to claim that life is a cosmic phenomenon, something that drifts between the spheres, like light, and like light transiently descends upon those fit to receive it.

Doubtless many can recall certain books which have greatly influenced their lives, and in my own case one stands out especially-a translation of Hofmeister's epoch-making treatise on the comparative morphology of plants. This book, studied while an undergraduate at the University of Michigan, was undoubtedly the most important factor in determining the trend of my botanical investigation for many years.

Nature is not personal. She is the compound of all these processes which move through the universe to effect the results we know as Life and of all the ordinances which govern that universe and that make Life continuous. She is no more the Hebrew's Jehovah than she is the Physicist's Force; she is as much Providence as she is Electricity; she is not the Great Pattern any more than she is the Blind Chance.

Every child should have mud pies, grasshoppers, water bugs, tadpoles, frogs, mud turtles, elderberries, wild strawberries, acorns, chestnuts, trees to climb. Brooks to wade, water lilies, woodchucks, bats, bees, butterflies, various animals to pet, hayfields, pine-cones, rocks to roll, sand, snakes, huckleberries and hornets; and any child who has been deprived of these has been deprived of the best part of education.

I'm the most experienced cinematographer in this medium, so there's no point in having that extra conversation in the middle of the loop. You're making the film in relation to what's happening now, and you can't really affect what's happening now. It's not like you're in control of anything in front of the camera. If you're calling yourself the director and you're not the cinematographer, I think you're kidding yourself.

Never to have seen anything but the temperate zone is to have lived on the fringe of the world. Between the Tropic of Capricorn and the Tropic of Cancer live the majority of all the plant species, the vast majority of the insects, most of the strange ... quadrupeds, all of the great and most of the poisonous snakes and large lizards, most of the brilliantly colored sea fishes, and the strangest and most gorgeously plumaged of the birds.
