Species Quotes

500+ Sourced quotes

A grain in the balance will determine which individual shall live and which shall die - which variety or species shall increase in number, and which shall decrease, or finally become extinct.

The sacrifice of personal existence is necessary to secure the preservation of the species.

It occurred to me, in 1837, that something might perhaps be made of this question (the origin of the species) by patiently accumulating and reflecting on all sorts of facts which could possibly have any bearing on it

I have heard, by roundabout channel, that Herschel says my book [The Origin of the Species] "is the law of higgledy-piggledy." What this exactly means I do not know, but it is evidently very contemptuous. If true this is a great blow and discouragement.

Often in evolutionary processes a species must adapt to new conditions in order to survive. Today the atomic bomb has altered profoundly the nature of the world as we know it, and the human race consequently finds itself in a new habitat to which it must adapt its thinking.

Albert Einstein

In pain there is as much wisdom as in pleasure: like the latter it is one of the best self preservatives of a species.

Friedrich Nietzsche

Let us beware of saying that death is the opposite of life. The living being is only a species of the dead, and a very rare species.

Friedrich Nietzsche

It is generally allowed, that no man ever found the happiness of possession proportionate to that expectation which incited his desire, and invigorated his pursuit; nor has any man found the evils of life so formidable in reality, as they were described to him by his own imagination; every species of distress brings with it some peculiar supports, some unforeseen means of resisting, or powers of enduring.

In every part of the universe we observe means adjusted with the nicest artifice to the ends which they are intended to produce; and in the mechanism of a plant, or animal body, admire how every thing is contrived for advancing the two great purposes of nature, the support of the individual, and the propagation of the species.

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.

Men will seem to see new destructions in the sky. The flames that fall from it will seem to rise in it and to fly from it with terror. They will hear every kind of animals speak in human language. They will instantaneously run in person in various parts of the world, without motion. They will see the greatest splendour in the midst of darkness. O! marvel of the human race! What madness has led you thus! You will speak with animals of every species and they with you in human speech. You will see yourself fall from great heights without any harm and torrents will accompany you, and will mingle with their rapid course.

Leonardo da Vinci

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

All interpretation or observation of reality is necessarily fiction. In this case, the problem is that man is a moral animal abandoned in an amoral universe and condemned to a finite existence with no other purpose than to perpetuate the natural cycle of the species. It is impossible to survive in a prolonged state of reality, at least for a human being. We spend a good part of our lives dreaming, especially when we're awake.

Carlos Ruiz Zafón

I do not think more credit is due a man for defining a species, than to a carpenter for making a box. But I am foolish and rabid against species-mongers, or rather against their vanity; it is useful and necessary work which must be done; but they act as if they had actually made the species, and it was their own property.

Even a superficial glance is sufficient to show that all the innumerable forms in which the life-urge of Nature manifests itself are subject to a fundamental law - one may call it an iron law of Nature - which compels the various species to keep within the definite limits of their own life-forms when propagating and multiplying their kind.

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.

I can only speak with that species of indefinite definiteness which mathematicians are, at times, forced to put up with in certain algebraic formulae.

Edgar Allan Poe

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

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

Napoleon I of France

When we descend to details, we can prove that no one species has changed (i.e., we cannot prove that a single species has changed): nor can we prove that the supposed changes are beneficial, which is the groundwork of the theory. Nor can we explain why some species have changed and others have not.

We sacrifice other species to our own not because our own has any objective metaphysical privilege over others, but simply because it is ours. It may be very natural to have this loyalty to our own species, but let us hear no more from the naturalists about the "sentimentality" of anti-vivisectionists. If loyalty to our own species - preference for man simply because we are men - is not sentiment, then what is?

I would dare say that today this species is facing a very real and true danger of extinction, and no one can be sure, listen to this well, no one can be sure that it will survive this danger.
Well, the fact that the species would not survive was discussed about 2,000 years ago. I remember that when I was a student I heard of the Apocalypse, a book of prophesy in the Bible. Apparently, 2000 years ago someone realized that this weak species could one day disappear.

Mere chance … alone would never account for so habitual and large an amount of difference as that between varieties of the same species.
