A Quote by Thomas Jefferson

The movements of nature are in a never ending circle. The animal species which has once been put into a train of motion, is still probably moving in that train. For if one link in nature's chain might be lost, another and another might be lost, till this whole system of things should evanish by piece-meal; a conclusion not warranted by the local disappearance of one or two species of animals, and opposed by the thousands and thousands of instances of the renovating power constantly exercised by nature for the reproduction of all her subjects, animal, vegetable, and mineral.

For if one link in nature's chain might be lost, another might be lost, until the whole of things will vanish by piecemeal.

Thomas Jefferson

It must be stressed that there is nothing insulting about looking at people as animals. We are animals, after all. Homo sapiens is a species of primate, a biological phenomenon dominated by biological rules, like any other species. Human nature is no more than one particular kind of animal nature. Agreed, the human species is an extraordinary animal; but all other species are also extraordinary animals, each in their own way, and the scientific man-watcher can bring many fresh insights to the study of human affairs if he can retain this basic attitude of evolutionary humility.

Desmond Morris

An Individual, whatever species it might be, is nothing in the Universe. A hundred, a thousand individuals are still nothing. The species are the only creatures of Nature, perpetual creatures, as old and as permanent as it. In order to judge it better, we no longer consider the species as a collection or as a series of similar individuals, but as a whole independent of number, independent of time, a whole always living, always the same, a whole which has been counted as one in the works of creation, and which, as a consequence, makes only a unity in Nature.

Georges-Louis Leclerc, Comte de Buffon

Secondly, man sins against nature when he goes against his generic nature, that is to say, his animal nature. Now, it is evident that, in accord with natural order, the union of the sexes among animals is ordered towards conception. From this it follows that every sexual intercourse that cannot lead to conception is opposed to man's animal nature.

Thomas Aquinas

But we must here state that we should not see anything if there were a vacuum. But this would not be due to some nature hindering species, and resisting it, but because of the lack of a nature suitable for the multiplication of species; for species is a natural thing, and therefore needs a natural medium; but in a vacuum nature does not exist.

Roger Bacon

Sometimes I think man needs to feel a special position within nature, and this leads him to believe that he is either specially hated by other animals or specially cherished. Instead of the truth, which is that he's just another animal on the plain. A smart one, but just another animal.

Michael Crichton

Man is merely a frequent effect, a monstrosity is a rare one, but both are equally natural, equally inevitable, equally part of the universal and general order. And what is strange about that? All creatures are involved in the life of all others, consequently every species... all nature is in a perpetual state of flux. Every animal is more or less a human being, every mineral more or less a plant, every plant more or less an animal... There is nothing clearly defined in nature.

John Dewey

Nothing comes to pass in nature, which can be set down to a flaw therein; for nature is always the same, and everywhere one and the same in her efficacy and power of action: that is, nature's laws and ordinances, whereby all things come to pass and change from one form to another, are everywhere and always the same; so that there should be one and the same method of understanding the nature of all things whatsoever, namely, through nature's universal laws and rules.

Baruch Spinoza

I fear animals regard man as a creature of their own kind which has in a highly dangerous fashion lost its healthy animal reason - as the mad animal, as the laughing animal, as the weeping animal, as the unhappy animal.

Friedrich Nietzsche

Natural bodies are divided into three kingdomes of nature: viz. the mineral, vegetable, and animal kingdoms. Minerals grow, Plants grow and live, Animals grow, live, and have feeling.

Carl Linnaeus

Because of the nature of my life, because I train a great many people, I come upon such a huge variety of human species, as well as the earth species for that matter.

Jean Houston

Nature can't evolve a species that hasn't the will to survive. Individuals might be bred to sacrifice themselves, but the race as a whole can never cease to exist.

Orson Scott Card

Dogs are not 'people' of another species. They are another species. To train and care for them properly, to show them how to live in our complex world, requires first and foremost that we understand that.

Jon Katz

MAN, n. An animal so lost in rapturous contemplation of what he thinks he is as to overlook what he indubitably ought to be. His chief occupation is extermination of other animals and his own species, which, however, multiplies with such insistent rapidity as to infest the whole habitable earth and Canada.

Ambrose Bierce

If all the sins of the flesh are worthy of condemnation because by them man allows himself to be dominated by that which he has of the animal nature, much more deserving of condemnation are the sins against nature by which man degrades his own animal nature.

Thomas Aquinas

Now the basest thought possible concerning man is, that he has no spiritual nature; and the foolishest misunderstanding of him possible is, that he has, or should have, no animal nature. For his nature is nobly animal, nobly spiritual,--coherently and irrevocably so; neither part of it may, but at its peril, expel, despise, or defy the other.

John Ruskin
