George Gaylord Simpson on Being the Product of a Purposeless Natural Process
Although many details remain to be worked out, it is already evident that all the objective phenomena of the history of life can be explained by purely naturalistic or, in a proper sense of the sometimes abused word, materialistic factors. They are readily explicable on the basis of differential reproduction in populations (the main factor in the modern conception of natural selection) and of the mainly random interplay of the known processes of heredity. … Man is the result of a purposeless and natural process that did not have him in mind. He was not planned. He is a state of matter, a form of life, a sort of animal, and a species of the Order Primates, akin nearly or remotely to all of life and indeed to all that is material. It is, however, a gross representation to say that he is just an accident or nothing but an animal. Among all the myriad forms of matter and of life on the earth, or as far as we know in the universe, man is unique. He happens to present the highest form of organization of matter and energy that has ever appeared. Recognition of this kinship with the rest of the universe is necessary for understanding him, but his essential nature is defined by qualities found nowhere else, not by those he has in common with apes, fishes, trees, fire, or anything other than himself.
Michael Polanyi on Accidental Formation of Species
This [distinguishing patterns from randomness] bears on the theory that the different living species have come into existence by accidental mutations. This can be affirmed only if, first you accredit the distinctive pattern of living beings as exhibiting a peculiar orderliness which you trust yourself to appraise, and second you accept at the same time the belief that evolution has taken place by a vastly improbable coincidence of random events combining to an orderly shape of a highly distinctive character. However, if we are to identify — as I am about to suggest — the presence of significant order with the operation of an ordering principle, no highly significant order can ever be said to be solely due to an accidental collocation of atoms, and we must conclude therefore that the assumption of an accidental formation of the living species is a logical muddle. It appears to be a piece of equivocation, unconsciously prompted by the urge to avoid facing the problem set to us by the fact that the universe has given birth to these curious beings, including people like ourselves. To say that this result was achieved by natural selection is entirely beside the point. Natural selection tells us only why the unfit failed to survive and not why any living beings, either fit or unfit, ever came into existence.
William Jennings Bryan on the Degradation of Man
No circle is reserved for man alone… He is, according to the diagram, shut up in the little circle entitled ‘Mammals,’ with thirty-four hundred and ninety-nine other species of mammals…. What shall we say of the intelligence, not to say religion, of those who are so particular to distinguish between fishes and reptiles and birds, but put a man with an immortal soul in the same circle with the wolf, the hyena, and the skunk? What must be the impression made upon children by such a degradation of man?
Wilberforce and Huxley on ‘Yo Momma’ and Ape Ancestry
In the course of a debate between Bishop Wilberforce and Huxley, in which Huxley defended the doctrine of evolution, the Bishop said: “I should like to ask Professor Huxley as to his belief in being descended from an ape. Is it on his grandfather’s or his grandmother’s side that the ape ancestry comes in?” Then, in a graver tone, he asserted that the views of Huxley were contrary to the revelations of Scripture. In the course of his refutation Huxley said: “I asserted — and I repeat — that a man has no reason to be ashamed of having an ape for his grandfather. If there were any ancestor whom I should feel shame in recalling, it would rather be a man who plunges into scientific questions with which he has no real acquaintance, only to obscure them by an aimless rhetoric, and to distract the attention of his hearers from the real point at issue by eloquent digressions and skilled appeals to religious prejudice.”
G.K. Chesterton on Saving Humanity
When we have for some few frantic centuries tortured ourselves to save minkind, it will then be “time enough” to discuss whether they can possibly be saved. When, in the case of infant mortality, for example, we have exhausted ourselves with the earth-shaking efforts required to save the life of every individual baby, it will then be time enough to consider whether every individual baby would not have been happier dead. We are to remove mountains and bring the millenium, because then we can have a quiet moment to discuss whether the millenium is at all desirable. Here we have the low-water mark of the impotence of the sad reformer. And here we have the reason of the the paradoxical triumph of the happy one. His triumph is a religious triumph; it rests upon his perpetual assertion of the value of the human soul and of human daily life. It rests upon his assertion that human life is enjoyable because it is human. And he will never admit, like so many compassionate pessimists, that human life ever ceases to be human. He does not merely pity the lowness of men; he feels an insult to their elevation. Brute pity should be given only to the brutes. Cruelty to animals is cruelty and a vile thing; but cruelty to a man is not tyranny, it is rebellion, for man is loyal. Now, the practical weakness of the vast mass of modern pity for the poor and the oppressed is precisely that it is merely pity; the pity is pitiful, but not respectful. Men feel that the cruelty to the poor is a kind of cruelty to animals. They never feel that it is injustice to equals; nay, it is treachery to comrades. This dark, scientific pity, this brutal pity, has an elemental sincerity of its own; but it is entirely useless for all ends of social reform. Democracy swept Europe with the sabre when it was founded upon the Rights of Man. It has done literally nothing at all since it has been founded only upon the wrongs of man. Or, more strictly speaking, its recent failures have been due to its not admitting the existence of any rights or wrongs, or indeed of any humanity. Evolution (the sinister enemy of revolution) does not especially deny the existence of God; what it does deny is the existence of man. And all the despair about the poor, and the cold and repugnant pity for them, has been largely due to the vague sense that they have literally relapsed into the state of the lower animals.
Charles Darwin on the Need for Mechanism
In considering the Origin of Species, it is quite conceivable that a naturalist, reflecting on the mutual affinities of organic beings, on their embryological relations, their geographical distribution, geological succession, and such other facts, might come to the conclusion that each species had not been independently created, but had descended, like varieties, from other species. Nevertheless, such a conclusion, even if well founded, would be unsatisfactory, until it could be shown how the innumerable species inhabiting this world have been modified, so as to acquire that perfection of structure and coadaptation which most justly excites our admiration.
On the Origin of Species
The publication of Darwin’s The Origin of Species in 1859 marked a dramatic turning point in scientific thought. The volume had taken Darwin more than twenty years to publish, in part because he envisioned the storm of controversy it was certain to unleash. Indeed, selling out its first edition on its first day, The Origin of Species revolutionized science, philosophy, and theology. Darwin’s reasoned, documented arguments carefully advance his theory of natural selection and his assertion that species were not created all at once by a divine hand but started with a few simple forms that mutated and adapted over time. Whether commenting on his own poor health, discussing his experiments to test instinct in bees, or relating a conversation about a South American burrowing rodent, Darwin’s monumental achievement is surprisingly personal and delightfully readable. Its profound ideas remain controversial even today, making it the most influential book in the natural sciences ever written—an important work not just to its time but to the history of humankind. ~ Publisher’s Description
Charles Darwin on Transitional Forms
The number of intermediate varieties, which have formerly existed on the earth, (must) be truly enormous. Why then is not every geological formation and every stratum full of such intermediate links? Geology assuredly does not reveal any such finely graduated organic chain; and this, perhaps, is the most obvious and gravest objection which can be urged against my theory.
Charles Darwin on Irreducible Complexity
If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous successive slight modifications, my theory would absolutely break down. But I can find out no such case. No doubt many organs exist of which we do not know the transitional grades … We should be extremely cautious in concluding that an organ could not have been formed by transitional gradations of some kind.
David Hume on Blind Nature
Look round this universe. What an immense profusion of beings, animated and organised, sensible and active! You admire this prodigious variety and fecundity. But inspect a little more narrowly these living existences, the only beings worth regarding. How hostile and destructive to each other! How insufficient all of them for their own happiness! How contemptible or odious to the spectator! The whole presents nothing but the idea of a blind Nature, impregnated by a great vivifying principle, and pouring forth from her lap, without discernment or parental care, her maimed and abortive children!
