“I have said that President Lincoln was a white man, and shared the prejudices common to his countrymen towards the colored race. Looking back to his times and to the condition of his country, we are compelled to admit that this unfriendly feeling on his part may be safely set down as one element of his wonderful success in organizing the loyal American people for the tremendous conflict before them, and bringing them safely through that conflict. His great mission was to accomplish two things. First, to save his country from dismemberment and ruin; and, second, to free his country from the great crime of slavery. To do one or the other, or both, he must have the earnest sympathy and the powerful cooperation of his loyal fellow-countrymen. Without this primary and essential condition to success his efforts must have been vain and utterly fruitless. Had he put the abolition of slavery before the salvation of the Union, he would have inevitably driven from him a powerful class of the American people and rendered resistance to rebellion impossible. Viewed from the genuine abolition ground, Mister Lincoln seemed tardy, cold, dull, and indifferent; but measuring him by the sentiment of his country, a sentiment he was bound as a statesman to consult, he was swift, zealous, radical, and determined. Though Mister Lincoln shared the prejudices of his white fellow-countrymen against the Negro, it is hardly necessary to say that in his heart of hearts he loathed and hated slavery. The man who could say, 'Fondly do we hope, fervently do we pray, that this mighty scourge of war shall soon pass away, yet if God wills it continue till all the wealth piled by two hundred years of bondage shall have been wasted, and each drop of blood drawn by the lash shall have been paid for by one drawn by the sword, the judgments of the Lord are true and righteous altogether', gives all needed proof of his feeling on the subject of slavery. He was willing, while the south was loyal, that it should have its pound of flesh, because he thought that it was so nominated in the bond; but farther than this no earthly power could make him go.”

“Contrary to what is often thought, excessive hygiene, that is staying in an antibacterial environment, does not necessarily lead to a better health, sometimes it even causes health deterioration. Indirect proof may be that among children of rural backgrounds allergic diseases is less than in urban children. This is because children in the countryside are in contact with a lot more bacteria. You can see that exaggeration is unhealthy in every respect.”

“The statement is so frequently made that the differential calculus deals with continuous magnitude, and yet an explanation of this continuity is nowhere given; even the most rigorous expositions of the differential calculus do not base their proofs upon continuity but, with more or less consciousness of the fact, they either appeal to geometric notions or those suggested by geometry, or depend upon theorems which are never established in a purely arithmetic manner. Among these, for example, belongs the above mentioned theorem, and a more careful investigation convinced me that this theorem, or any one equivalent to it, can be regarded in some way as a sufficient basis for infinitesimal analysis. It then only remained to discover its true origin in the elements of arithmetic and thus at the same time to secure a real definition of the essence of continuity. I succeeded Nov. 24, 1858.”

“[T]hough religious thinkers will fight fiercely to show its standpoint to be the one religion really sanctions, each religion has signposts pointing in both ways. One the one hand towards a fundamentalist, authoritarian strain that insists if you want to be faithful you have to crucify your intellect; that is to believe just because your belief is absurd. And on the other hand, each of the three western religions has a rationalist tradition… far from viewing our capacity for reason as threatening our capacity to obey god, this tradition sees thinking as its very fulfillment. There are actually some wonderful Jewish parables, which show God laughing with pleasure as human beings defeat him with a particularly good argument. That is, god would rather be impressed than right on certain Jewish rationalist traditions. So if reason is God’s gift then he meant us to use it even against him if he is wrong or hasty. On this tradition our ability to make sense of the world whether with science or through the right moral actions, is just one more proof of gods goodness.”

“How dare Huckabee say that school is where we don’t want to talk about eternity, life, responsibility, or accountability. I do want to talk about those things -where religion does not. Why? Because religion offers a way to deny accountability for anything. Reverse the burden of proof. Assert as fact that which is not evidently true. Don’t have a basis for any claim; assume your conclusions on the veracity of your own conviction unsupported by anything, or on citation of any false-authority who’s comments you can present as though they agree with you. Announce in advance that you will never admit when you’re wrong; that you will continue to defend your biased preconceptions to the automatic rejection –without consideration- of any evidence or arguments that will ever arise to the contrary. This is what every creationist organization says in their ‘statement of faith’. Look them up. This is where they openly admit that they have no accountability.”

“And here I cannot help mentioning a very ridiculous show of a learned pig, which of late days attracted much of the public notice, and at the polite end of the town. This pig, which indeed was a large unwieldy hog, being taught to pick up letters written upon pieces of cards, and to arrange them at command, gave great satisfaction to all who saw him, and filled his tormenter's pocket with money. One would not have thought that a hog had been an animal capable of learning: the fact, however, is another proof of what may be accomplished by assiduity; for the showman assured a friend of mine, that he had lost three very promising brutes in the course of training, and that the phenomenon then exhibited had often given him reason to despair of success.”

“Some of my readers may find themselves thinking that the mere fact that millions of human beings, including many highly intelligent and deeply thoughtful ones, have had strongly held religious beliefs is itself a reason for giving them serious intellectual attention — not necessarily for believing them, of course, but for finding them interesting and for treating them with respect. I would agree with this if the reasons given for them commanded respect. But I have yet to encounter such reasons. What are claimed as proofs are not proofs, and all such "proofs" have long since been discredited, the most important of them by Christians themselves, such as Kant. Yet they go on being trotted out: assertions are made without evidence; mutually contradictory claims proliferate; historical knowledge is defied; mistranslations abound; language is used in a way that slithers unacknowledged between literal meaning and metaphor; the whole vocabulary rests on unsecured presuppositions. Superstitions and belief in magic are perennial in just the same way as religion, and something near to being universal among mankind; and why this is so may be interesting, but in most cases the beliefs themselves are devoid of interesting content, at least to me.”

“That is to say, within less than twenty years after the Constitution was formed, and in obedience to that general opinion of the time which condemned slavery as a sin in morals and a blunder in economy, eight of the States had abolished it by law — four of them having already done so when the instrument was framed; and Mr. Douglas might as justly quote the fact that there were slaves in New York up to 1827 as proof that the public opinion of the State sanctioned slavery, as to try to make an argument of the fact that there were slave laws upon the statute-books of the original States. He forgets that there was not in all the colonial legislation of America one single law which recognized the rightfulness of slavery in the abstract; that in 1774 Virginia stigmatized the slave-trade as 'wicked, cruel, and unnatural'; that in the same year Congress protested against it 'under the sacred ties of virtue, honor, and love of country'; that in 1775 the same Congress denied that God intended one man to own another as a slave; that the new Discipline of the Methodist Church, in 1784, and the Pastoral Letter of the Presbyterian Church, in 1788, denounced slavery; that abolition societies existed in slave States, and that it was hardly the interest even of the cotton-growing States, where it took a slave a day to clean a pound of cotton, to uphold the system. Mr. Douglas incessantly forgets to tell us that Jefferson, in his address to the Virginia Legislature of 1774, says that 'the abolition of domestic slavery is the greatest object of desire in these colonies, where it was unhappily introduced in their infant state'; and while he constantly remembers to remind us that the Jeffersonian prohibition of slavery in the territories was lost in 1784, he forgets to add that it was lost, not by a majority of votes — for there were sixteen in its favor to seven against it — but because the sixteen votes did not represent two thirds of the States; and he also incessantly forgets to tell us that this Jeffersonian prohibition was restored by the Congress of 1785, and erected into the famous Northwest Ordinance of 1787, which was re-enacted by the first Congress of the United States and approved by the first President.”

“As Prince Bismarck, in the ’60s, wanted to move the “Acheron” of socialism, … it was of course not love for socialism or knowledge of socialism that led Prince Bismarck to do this. He understood nothing about socialism at that time, and never did understand anything about it down to his death; in fact, he never had any conception of the moving forces of political and social life at all. There probably never lived at any time in any country a “statesman” who was less scientific, who had less knowledge, and who relied so purely on experience and a sort of half-gambler, half-peddler cunning, as Bismarck. Those offers to socialists place in the clearest light the untruthfulness of Prince Bismarck’s claim that he always regarded the social democracy as incompatible with the existence of the state. Bismarck wanted to use socialism for the purpose of breaking up and dissolving the bourgeois liberal opposition, especially the Progressive party. This, in itself, is the most conclusive proof that he had no conception of the real nature of socialism. Of course the fate of the boy magician was repeated. The elemental force which was conjured up grew over the head of the dabbler, and he did not get the best of socialism; socialism got the best of him.”

“The two great conceptual revolutions of twentieth-century science, the overturning of classical physics by Werner Heisenberg and the overturning of the foundations of mathematics by Kurt Gödel, occurred within six years of each other within the narrow boundaries of German-speaking Europe. … A study of the historical background of German intellectual life in the 1920s reveals strong links between them. Physicists and mathematicians were exposed simultaneously to external influences that pushed them along parallel paths. … Two people who came early and strongly under the influence of Spengler's philosophy were the mathematician Hermann Weyl and the physicist Erwin Schrödinger. … Weyl and Schrödinger agreed with Spengler that the coming revolution would sweep away the principle of physical causality. The erstwhile revolutionaries David Hilbert and Albert Einstein found themselves in the unaccustomed role of defenders of the status quo, Hilbert defending the primacy of formal logic in the foundations of mathematics, Einstein defending the primacy of causality in physics. In the short run, Hilbert and Einstein were defeated and the Spenglerian ideology of revolution triumphed, both in physics and in mathematics. Heisenberg discovered the true limits of causality in atomic processes, and Gödel discovered the limits of formal deduction and proof in mathematics. And, as often happens in the history of intellectual revolutions, the achievement of revolutionary goals destroyed the revolutionary ideology that gave them birth. The visions of Spengler, having served their purpose, rapidly became irrelevant.”

“Looking carefully, one discovers at last that this gorgeous combination of all the hues of Paradise contains or hides a Last Judgment [....]

To the Virgin and her suppliants, as to us, who though outcasts in other churches can still hope in hers, the Last Judgment was not a symbol of God's justice or man's corruption but of her own infinite mercy. The Trinity judged, through Christ;— Christ loved and pardoned, through her. She wielded the last and highest power on earth and in hell. In the glow and beauty of her nature, the light of her Son's infinite love shone as the sunlight through the glass, turning the Last Judgement itself into the highest proof of her divine and supreme authority. The rudest ruffian of the middle-ages, when he looked at this Last Judgment, laughed, for what was the Last Judgment to her! An ornament, a play-thing, a pleasure! a jewelled decoration which she wore on her breast! Her chief joy was to pardon; her eternal instinct was to love; her deepest passion was pity! On her imperial heart the flames of hell showed only the opaline colors of heaven. Christ the Trinity might judge as much as he pleased, but Christ the Mother would rescue; and her servants could look boldly into the flames.”

“Has, then, the influence of the crown increased since the Revolution? Down to the period of 1782 I believe the fact will not be much disputed. It was upon the notoriety of the fact, and the bad consequences it had produced, that the motions of the right hon. gentleman in favour of reform were founded. That it has increased, I think every impartial man must be compelled to admit…If, then, while the influence of the crown has so manifestly advanced, while the cause of liberty has remained the same, or has sustained a diminution of its strength, can it be said that we are standing upon the establishment of the Revolution, and adhering to the principles which it ascertained? It is, then, upon this ground of experience and the evidence of facts, upon proof of positive inconvenience and real declination from its original purity, that I should propose to recall our constitution to its true principles and to amend the system of our representation.”

“What is the world that lies around our own? Shadowy, unsubstantial, and wonderful are the viewless elements, peopled with spirits powerful and viewless as the air which is their home. From the earth's earliest hour, the belief in the supernatural has been universal. At first the faith was full of poetry; for, in those days, the imagination walked the earth even as did the angels, shedding their glory around the children of men. The Chaldeans watched from their lofty towers the silent beauty of night — they saw the stars go forth on their appointed way, and deemed that they bore with them the mighty records of eternity. Each separate planet shone on some mortal birth, and as its aspect was for good or for evil, such was the aspect of the fortunes that began beneath its light. Those giant watch-towers, with their grey sages, asked of the midnight its mystery, and held its starry roll to be the chronicle of this breathing world. Time past on, angels visited the earth no more, and the divine beliefs of young imagination grew earthlier. Yet poetry lingered in the mournful murmur of the oaks of Dodona, and in the fierce war song of the flying vultures, of whom the Romans demanded tidings of conquest. But prophecy gradually sank into divination, and it is a singular proof of the extent both of human credulity and of curiosity, to note the various methods that have had the credit of forestalling the future. From the stars to a tea-cup is a fall indeed”

“…mention is made of evidences in favour of the big bang, like the microwave background. It is a relic radiation supposed to have formed very early after the big bang. As the universe expanded it cooled down and its present temperature is at 2.7 K. The only fact which is measurable or has been measured is that there is a background of 2.7 K temperature. Saying that this is left over from the early universe is a speculation. It is a part of a theoretical structure I am supposed to have built which enables me to say that it is a relic of that early-on era. We have given a different explanation. Helium forms by fusion of hydrogen inside a star like the sun, leading to radiation. One can ask the following question: if all the helium that you find in the universe was formed in stars sometime or the other, how much radiation will be formed and what would its temperature be? The answer is 2.7 K. If you ask a big bang person why his relic radiation today has a temperature of 2.7 K he doesn’t know. This alternative explanation that I’m giving is able to do more than what the big bang does. So I don’t see any reason to say we have a very positive proof of the big bang happening.”

“When I came back to Paris in 1931, after a long convalescence in the South, the 'Abstraction-Création' group had just be founded. Vantongerloo had been given our mailing list. At the same time I learned of Van Doesburg's death in Davos. The first issue of 'Abstraction-Création' came off the press just a year later, printed in the same dusty small shop that had brought out 'Cercle et Carré' and where I had earned a meagre living as a non-union proof-reader and make-up man. 'Abstraction-Création' had a much wider influence than its predecessor. From 1932 to 1936 an annual cahier presented reproductions and statements by painters.”

Archaeopteryx. Wow. And this somehow gets the impression to the kids, "Wow, we've got proof that dinosaurs turned to birds. Here's one here with feathers on it." They're lying. It's still in the textbooks, I mean today, about Archaeopteryx. And it's been proven years ago, Archaeopteryx was just a bird, a perching bird. Alan Feduccia, who believes in evolution, says it's not a missing link. It had the right features for flight. All the features of the brain were for flight, okay? Archaeopteryx means "ancient wing," and he had claws on his wings. Well, that's kind of unusual, okay. But twelve birds today have claws on their wings. There is the swan, the ibis, the hoatzin… several birds have claws. They say, "Well, he had teeth in his beak." Well, not many birds have teeth, some do. There's the hummingbird that has teeth in his beak. But most birds don't have teeth, I agree. Actually, some mammals have teeth, some don't. Some birds have teeth, some don't.

“The whole world knows that virtue consists in the subjugation of one's passions, or in self-renunciation. It is not just the Christian world, against whom Nietzsche howls, that knows this, but it is an eternal supreme law towards which all humanity has developed, including Brahmanism, Buddhism, Confucianism, and the ancient Persian religion. And suddenly a man appears who declares that he is convinced that self-renunciation, meekness, submissiveness and love are all vices that destroy humanity (he has in mind Christianity, ignoring all the other religions).

One can understand why such a declaration baffled people at first. But after giving it a little thought and failing to find any proof of the strange propositions, any rational person ought to throw the books aside and wonder if there is any kind of rubbish that would not find a publisher today. But this has not happened with Nietzsche´s books. The majority of pseudo-enlightened people seriously look into the theory of the Übermensch, and acknowledge its author to be a great philosopher, a descendant of Descartes, Leibniz and Kant. And all this has come about because the majority of pseudo-enlightened men of today object to any reminder of virtue, or to its chief premise: self-renunciation and love—virtues that restrain and condemn the animal side of their life. They gladly welcome a doctrine, however incoherently and disjointedly expressed, of egotism and cruelty, sanctioning the idea of personal happiness and superiority over the lives of others, by which they live.”

“Enlightenment … asks, innocently and subversively, for proofs, sources, and evidence. At the beginning it solemnly avers that it would willingly believe everything, if only it could find someone to convince it. Here it becomes clear that the biblical texts, taken philologically, remain themselves their only witness. Their revelatory character is their own claim, and it can be believed or not; the church, which elevates this revelatory character to the status of a grand dogma, itself plays only the role of an interpreter. With his radical biblicism, Luther rejected the church’s claim to authority. This repudiation then repeats itself on the higher level through biblicism itself. For text remains text, and every assertion that it is divinely inspired can, in turn, be only a human, fallible assertion. With every attempt to grasp the absolute source, critique comes up against relative, historical sources that only ever assert the Absolute. The miracles spoken about in the Bible to legitimate God’s power are only reports of miracles for which there are no longer any means of verification. The revelatory claim is stuck in a philological circle.”

“For too long, African societies have been identified as superstitious, consisting of people who cannot question, reason or think critically. Dogma and blind faith in superstition, divinity and tradition are said to be the mainstay of popular thought and culture. African science is often equated with witchcraft and the occult; African philosophy with magical thinking, myth-making and mysticism, African religion with stone-age spiritual abracadabra, African medicine with folk therapies often involving pseudoscientific concoctions inspired by magical thinking. Science, critical thinking and technological intelligence are portrayed as Western — as opposed to universal — values, and as alien to Africa and to the African mindset. An African who thinks critically or seeks evidence and demands proofs for extraordinary claims is accused of taking a “white” or Western approach. An African questioning local superstitions and traditions is portrayed as having abandoned or betrayed the essence of African identity. Skepticism and rationalism are regarded as Western, un-African, philosophies. Although there is a risk of overgeneralizing, there are clear indicators that the continent is still socially, politically and culturally trapped by undue credulity. Many irrational beliefs exist and hold sway across the region. These are beliefs informed by fear and ignorance, misrepresentations of nature and how nature works. These misconceptions are often instrumental in causing many absurd incidents, harmful traditional practices and atrocious acts.”

“The Pythagoreans discovered the existence of incommensurable lines, or of irrationals. This was, doubtless, first discovered with reference to the diagonal of a square which is incommensurable with the side, being in the ratio to it of √2 to 1. The Pythagorean proof of this particular case survives in Aristotle and in a proposition interpolated in Euclid's Book X.; it is by a reductio ad absurdum proving that, if the diagonal is commensurable with the side, the same number must be both odd and even. This discovery of the incommensurable… showed that the theory of proportion invented by Pythagoras was not of universal application and therefore that propositions proved by means of it were not really established…. The fatal flaw thus revealed in the body of geometry was not removed till Eudoxus discovered the great theory of proportion (expounded in Euclid's Book V.), which is applicable to incommensurable as well as to commensurable magnitudes.”

This being the case, it is evident that the onus probandi [burden of proof] ought to lie with those who are willing to establish such an hypothesis, for it does not appear that Nature is in the habit of using one and the same mechanism with any two of our senses. Witness the vibration of air that makes sound, the effluvia that occasion smells, the particles that produce taste, the resistance or repulsive powers that affect the touch—all these are evidently suited to their respective organs of sense.”

“It is possible, after all, to 'fake' the 'realest' possible 'evidence' of heterosexuality: man or woman, one can participate in heterosexual marriage and even help produce a brood of spawn and still 'turn out' to have been 'living a lie,' to have been 'really' gay or lesbian all along. Precisely because there is no final 'proof' of heterosexuality, heterosexuality must constantly set about trying to prove itself, assert itself, insist on itself. Indeed, as Butler argues, heterosexuality as hegemonic institution is finally nothing more than its own repetitive self-insistence, nothing other than 'a constant and repeated effort to imitate its own idealizations' (Bodies 125). Or, as Janet E. Halley puts it in regard to legalistic constructions of heterosexuality, normative heterosexuality 'is a highly unstable, default characterization for people who have not marked themselves or been marked by other as homosexual.”

“The third aspect of my subject is that of science as a method of finding things out. This method is based on the principle that observation is the judge of whether something is so or not. All other aspects and characteristics of science can be understood directly when we understand that observation is the ultimate and final judge of the truth of an idea. But "prove" used in this way really means "test," in the same way that a hundred-proof alcohol is a test of the alcohol, and for people today the idea really should be translated as, "The exception tests the rule." Or, put another way, "The exception proves that the rule is wrong."”

“No sooner were the merits of Mr. Arkwright’s inventions fully understood, from the great increase of materials produced in a given time, and the superior quality of the goods manufactured; no sooner was it known, that his assiduity and great mechanical abilities were rewarded with success; than the very men, who had before treated him with contempt and derision, began to devise means to rob him of his inventions, and profit by his ingenuity. Every attempt that cunning could suggest for this purpose was made; by the seduction of his servants and workmen, (whom he had with great labour taught the business) a knowledge of his machinery and inventions was fully gained. From that time many persons began to pilfer something from him; and then by adding something else of their own, and by calling similar productions and machines by other names, they hoped to screen themselves from punishment. So many of these artful and designing individuals had at length infringed on his patent right, that he found it necessary to prosecute several: but it was not without great difficulty, and considerable expence, that he was able to make any proof against them; conscious that their conduct was unjustifiable, their proceedings were conducted with the utmost caution and secresy. Many of the persons employed by them were sworn to secresy, and their buildings and workshops were kept locked up, or otherwise secured. This necessary proceeding of Mr. Arkwright, occasioned, as in the case of poor Hargrave, an association against him, of the very persons whom he had served and obliged. Formidable, however, as it was, Mr. Arkwright persevered, trusting that he should obtain in the event, that satisfaction which he appeared to be justly entitled to.”

“I investigated reported Japanese atrocities committed by the Japanese Army in Nanking and elsewhere. Verbal accounts of reliable eyewitnesses and letters from individuals whose credibility is beyond question afford convincing proof that the Japanese Army behaved and is continuing to behave in a fashion reminiscent of Attila and his Huns. Not less than 300,000 Chinese civilians were slaughtered, many in cold blood.”

Kōki Hirota (1878–1948) Japanese politician executed
