Seeing this gradation and diversity of structure in one small, intimately related group of birds, one might really fancy that from an original paucity of birds in this archipelago, one species had been taken and modified for different ends.

I do not regard flesh-food as necessary for us at any stage and under any clime in which it is possible for human beings ordinarily to live, I hold flesh-food to be unsuited to our species.

The formation of different languages and of distinct species and the proofs that both have been developed through a gradual process, are curiously parallel.

There are three species of government: republican, monarchical, and despotic.

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

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?

On the possibility of contact with an alien civilization:

I think it would be a disaster. The extraterrestrials would probably be far in advance of us. The history of advanced races meeting more primitive people on this planet is not very happy, and they were the same species. I think we should keep our heads low.

Stephen Hawking

New truth is often uncomfortable, especially to the holders of power; nevertheless, amid the long record of cruelty and bigotry, it is the most important achievement of our intelligent but wayward species. '

Bertrand Russell

It seems to me that men of coarse and clumsy habits and of small knowledge do not deserve such fine instruments nor so great a variety of natural mechanism as men of speculation and of great knowledge; but merely a sack in which their food may be stowed and whence it may issue, since they cannot be judged to be any thing else than vehicles for food; for it seems to me they have nothing about them of the human species but the voice and the figure, and for all the rest are much below beasts.

Leonardo da Vinci

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

Nonviolence, pacifism, that's the greatest thing that I think the human species has to aspire to, because otherwise it's not going to be around.

Martin Scorsese

Slavery is such an atrocious debasement of human nature, that its very extirpation, if not performed with solicitious care, may sometimes open a source of serious evils. The unhappy man who has been treated as a brute animal, too frequently sinks beneath the common standard of the human species. The galling chains, that bind his body, do also fetter his intellectual faculties, and impair the social affections of his heart… To instruct, to advise, to qualify those, who have been restored to freedom, for the exercise and enjoyment of civil liberty… and to procure for their children an education calculated for their future situation in life; these are the great outlines of the annexed plan, which we have adopted.

Benjamin Franklin

Paper money has had the effect in your state that it will ever have, to ruin commerce, oppress the honest, and open the door to every species of fraud and injustice.

George Washington

I am quite conscious that my speculations run quite beyond the bounds of true science. … I inferred that genera & Families with very few species (i. e. from Extinction) would be apt (not necessarily always) to have narrow ranges & disjoined ranges. You will not perceive, perhaps, what I am driving at & it is not worth enlarging on, — but I look at Extinction as common cause of small genera & disjoined ranges & therefore they ought, if they behaved properly & as nature does not lie to go together!

Intolerance is a species of violence and therefore against our creed.

We human beings are not only the beneficiaries but also the stewards of other creatures. Thanks to our bodies, God has joined us so closely to the world around us that we can feel the desertification of the soil almost as a physical ailment, and the extinction of a species as a painful disfigurement. Let us not leave in our wake a swatch of destruction and death which will affect our own lives and those of future generations.

In living through this "great epoch," it is difficult to reconcile oneself to the fact that one belongs to that mad, degenerate species that boasts of its free will. How I wish that somewhere there existed an island for those who are wise and of good will! In such a place even I should be an ardent patriot!

Albert Einstein

I do not make films primarily for children. I make them for the child in all of us, whether we be six or sixty. Call the child "innocence". The worst of us is not without innocence, although buried deeply it might be. In my work I try to reach and speak to that innocence, showing it the fun and joy of living; showing it that laughter is healthy; showing it that the human species, although happily ridiculous at times, is still reaching for the stars.

Now when naturalists observe a close agreement in numerous small details of habits, tastes and dispositions between two or more domestic races, or between nearly-allied natural forms, they use this fact as an argument that all are descended from a common progenitor who was thus endowed; and consequently that all should be classed under the same species. The same argument may be applied with much force to the races of man. As it is improbable that the numerous and unimportant points of resemblance between the several races of man in bodily structure and mental faculties (I do not here refer to similar customs) should all have been independently acquired, they must have been inherited from progenitors who were thus characterised.

All satyagraha and fasting is a species of tyaga. It depends for its effects upon an expression of wholesome public opinion shorn of all bitterness.

Intelligence is based on how efficient a species became at doing the things they need to survive.

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

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.

Words are acoustical signs for concepts; concepts, however, are more or less definite image signs for often recurring and associated sensations, for groups of sensations. To understand one another, it is not enough that one use the same words; one also has to use the same words for the same species of inner experiences; in the end one has to have one's experiences in common.

Friedrich Nietzsche

All agree in recognising the fact that females exist in the human species; today as always they make up about one half of humanity. And yet we are told that femininity is in danger; we are exhorted to be women, remain women, become women. It would appear, then, that every female human being is not necessarily a woman; to be so considered she must share in that mysterious and threatened reality known as femininity.

Simone de Beauvoir
