Species Quotes

We are at the helm of not only our own physicality but our environment and other species, too, as sentient, conscious beings who can think of future and affect consequence, and create progeny with our minds as well as our bodies.

When the animals entered the Ark in pairs, one may imagine that allied species made much private remark on each other, and were tempted to think that so many forms feeding on the same store of fodder were eminently superfluous, as tending to diminish the rations.

The newspapers do little better. Their coverage of nonhuman animals is dominated by "human interest" events like the birth of a baby gorilla at the zoo, or by threats to endangered species; but developments in farming techniques that deprive millions of animals of freedom of movement go unreported.

We stand guard over works of art, but species representing the work of aeons are stolen from under our noses.

The question now at issue, whether the living species are connected with the extinct by a common bond of descent, will best be cleared up by devoting ourselves to the study of the actual state of the living world, and to those monuments of the past in which the relics of the animate creation of former ages are best preserved and least mutilated by the hand of time.

Literature was not promulgated by a pale and emasculated critical priesthood singing their litanies in empty churches — nor is it a game for the cloistered elect, the tinhorn mendicants of low calorie despair.
Literature is as old as speech. It grew out of human need for it, and it has not changed except to become more needed.
The skalds, the bards, the writers are not separate and exclusive. From the beginning, their functions, their duties, their responsibilities have been decreed by our species.

Life is neither static nor unchanging. With no individuality, there can be no change, no adaptation and, in an inherently changing world, any species unable to adapt is also doomed.

Our peasant music, naturally, is invariably tonal, if not always in the sense that the inflexible major and minor system is tonal. (An "atonal" folk-music, in my opinion, is unthinkable.) Since we depend upon a tonal basis of this kind in our creative work, it is quite self-evident that our works are quite pronouncedly tonal in type. I must admit, however, that there was a time when I thought I was approaching a species of twelve-tone music. Yet even in works of that period the absolute tonal foundation is unmistakable.

Our neural circuits were designed by natural selection to solve problems that our ancestors faced during our species' evolutionary history.

The human species, according to the best theory I can form of it, is composed of two distinct races, the men who borrow and the men who lend.

My generation is the first in my species to have put fitness next to godliness on the scale of things. Keeping in shape has become THE imperative of our middle age. The heaviest burden of guilt we carry into our forties is flab. Our sense of failure is measured by the grade on a stress test.

Experience of artificial fertilisation, such as is effected with ornamental plants in order to obtain new variations in colour, has led to the experiments which will here be discussed. The striking-regularity with which the same hybrid forms always reappeared whenever fertilisation took place between the same species induced further experiments to be undertaken, the object of which was to follow up the developments of the hybrids in their progeny.

As someone who's had the privilege of leading the human genome project, I've had the opportunity to study our own DNA instruction book at a level of detail that was never really possible before. It's also now been possible to compare our DNA with that of many other species. The evidence supporting the idea that all living things are descended from a common ancestor is truly overwhelming. I would not necessarily wish that to be so, as a Bible-believing Christian. But it is so. It does not serve faith well to try to deny that.

Francis Collins

Nature has introduced great variety into the landscape, but man has displayed a passion for simplifying it. Thus he undoes the built-in checks and balances by which nature holds the species within bounds.

I think it's a shame that something as creative and vital to the nature of the human species as story-telling is largely controlled by the soulless cretins known as publishers.

The plague of mankind is the fear and rejection of diversity: monotheism, monarchy, monogamy and, in our age, monomedicine. The belief that there is only one right way to live, only one right way to regulate religious, political, sexual, medical affairs is the root cause of the greatest threat to man: members of his own species, bent on ensuring his salvation, security, and sanity.

The truth is that we need invertebrates but they don't need us. If human beings were to disappear tomorrow, the world would go on with little change.... But if invertebrates were to disappear, I doubt that the human species could last more than a few months.

Genetics is the study of similarity between relatives, and the problem of human genetics is that, in a species with a family and social structure and a taboo against manipulating individual life histories experimentally, there is a confounding between the similarity of relatives that arises from biological causes and the similarity that arise from social causes.

Richard Lewontin

Natural inclinations are present in things from God, who moves all things. So it is impossible for the natural inclinations of a species to be toward evil in itself. But there is in all perfect animals a natural inclination toward carnal union. Therefore it is impossible for carnal union to be evil in itself.

To know who I am is a species of knowing where I stand. My identity is defined by the commitments and identifications which provide the frame or horizon within which I can try to determine from case to case what is good, or valuable, or what ought to be done, or what I endorse or oppose. In other words, it is the horizon within which I am capable of taking a stand.

Charles Taylor (philosopher)

Wolves should be saved and managed as part of the whole context, not because they are singled out as a special species.

How can anyone think so insanely that the human life has the same value and mankind, the same morality, independent of numbers? It is lucid to me that everytime a new child is born, the value of every human in world decreases slightly. It is obvious to me that the morality of the population explosion is wholly unlike than when man was a sparse, noble species in its beginning.

As a member of a self-interpreting species, one that fights to keep disharmony at a remove, I'm inclined to mention my tenderhearted attentions as a single parent before I get around to the fact that I hit their mother when we were together.

Experiments with a simple little machine, designed to mimic certain elementary features of animal behavior... Consisting only of two vacuum tubes, two motors, a photoelectric cell and a touch contact, all enclosed in a tortoise-shaped 'shell, the model was a species of artiﬁcial creature which could explore its surroundings and seek out favorable conditions. It was named Machine speculatrix.

William Grey Walter

Earth, the world, the fifth planet from the sun—the species that stands on two legs and roams this thin wet crust: it's changing, Lobey. It's not the same. Some people walk under the sun and accept that change, others close their eyes, clap their hands to their ears, and deny the world with their tongues.
