Species Quotes

500+ Sourced quotes

Every fact and every work exercises a fresh persuasion over every age and every new species of man. History always enunciates new truths.

Friedrich Nietzsche

Our vanity makes us exaggerate the importance of human life; the individual is nothing; Nature cares only for the species.

But suppose we were to teach creationism. What would be the content of the teaching? Merely that a creator formed the universe and all species of life ready-made? Nothing more? No details?

In July [1837] opened first note-book on Transmutation of Species. Had been greatly struck from about the month of previous March on character of South American fossils, and species on Galapagos Archipelago. These facts (especially latter), origin of all my views.

This World is not Conclusion.
A Species stands beyond —
Invisible, as Music —
But positive, as Sound.

Emily Dickinson

As geological time goes, it is but a moment since the human race began and only the twinkling of an eye since the arts of civilization were first invented. In spite of some alarmists, it is hardly likely that our species will completely exterminate itself. And so long as man continues to exist, we may be pretty sure that, whatever he may suffer for a time, and whatever brightness may be eclipsed, he will emerge sooner or later, perhaps strengthened and reinvigorated by a period of mental sleep. The universe is vast and men are but tiny specks on an insignificant planet. But the more we realize our minuteness and our impotence in the face of cosmic forces, the more astonishing becomes what human beings have achieved.

Bertrand Russell

Lastly, isolation, by checking immigration and consequently competition, will give time for any new variety to be slowly improved; and this may sometimes be of importance in the production of new species. If, however, an isolated area be very small, either from being surrounded by barriers, or from having very peculiar physical conditions, the total number of the individuals supported on it will necessarily be very small; and fewness of individuals will greatly retard the production of new species through natural selection, by decreasing the chance of the appearance of favourable variations.

The necessities of our condition require a thousand offices of tenderness, which mere regard for the species will never dictate.

It is a palpable falsehood to say we can have specie for our paper whenever demanded. Instead, then, of yielding to the cries of scarcity of medium set up by speculators, projectors and commercial gamblers, no endeavors should be spared to begin the work of reducing it by such gradual means as may give time to private fortunes to preserve their poise, and settle down with the subsiding medium; and that, for this purpose, the States should be urged to concede to the General Government, with a saving of chartered rights, the exclusive power of establishing banks of discount for paper.

Thomas Jefferson

When the labourer co-operates systematically with others, he strips off the fetters of his individuality, and develops the capabilities of his species.

The world is full of conflicts; and, overshadowing all minor conflicts, the titanic struggle between Communism and anti-Communism.
Almost everybody who is politically conscious has strong feelings about one or more of these issues; but we want you, if you can, to set aside such feelings and consider yourselves only as members of a biological species which has had a remarkable history, and whose disappearance none of us can desire.
We shall try to say no single word which should appeal to one group rather than to another. All, equally, are in peril, and, if the peril is understood, there is hope that they may collectively avert it.

Bertrand Russell

A primary object should be the education of our youth in the science of government. In a republic, what species of knowledge can be equally important? And what duty more pressing than communicating it to those who are to be the future guardians of the liberties of the country?

George Washington

Hope is itself a species of happiness, and, perhaps, the chief happiness which this world affords.

Whatever misanthropists may say, ingrates and the perverse are exceptions in the human species.

Napoleon I of France

Man is unique in organizing the mass murder of his own species.

The boundaries of the species, whereby men sort them, are made by men.

The natural historian is not a fisherman who prays for cloudy days and good luck merely; but as fishing has been styled "a contemplative man's recreation," introducing him profitably to woods and water, so the fruit of the naturalist's observations is not in new genera or species, but in new contemplations still, and science is only a more contemplative man's recreation.

Henry David Thoreau

For the female of the species is more deadly than the male.

Rudyard Kipling

But the Woman that God gave him, every fibre of her frame
Proves her launched for one sole issue, armed and engined for the same,
And to serve that single issue, lest the generations fail,
The female of the species must be deadlier than the male.

Rudyard Kipling

Most women defend themselves. It is the female of the species – it is the tigress and lioness in you – which tends to defend when attacked.

Margaret Thatcher

An unjust law is itself a species of violence. Arrest for its breach is more so. Now the law of nonviolence says that violence should be resisted not by counter-violence but by nonviolence. This I do by breaking the law and by peacefully submitting to arrest and imprisonment.

Human reason has this peculiar fate that in one species of its knowledge it is burdened by questions which, as prescribed by the very nature of reason itself, it is not able to ignore, but which, as transcending all its powers, it is also not able to answer.

To sell the overplus I cannot, because I am principled against this kind of traffic in the human species. To hire them out, is almost as bad, because they could not be disposed of in families to any advantage, and to disperse the families I have an aversion. What then is to be done? Something must or I shall be ruined; for all the money (in addition to what I raise by Crops, and rents) that have been received for Lands, sold within the last four years, to the amount of Fifty thousand dollars, has scarcely been able to keep me a float.

George Washington

The reproduction of mankind is a great marvel and mystery. Had God consulted me in the matter, I should have advised him to continue the generation of the species by fashioning them of clay, in the way Adam was fashioned.

Every species, human and subhuman, has some distinguishing mark, so that you can tell a man from a beast, or a dog from a cow.
