"If it is not totalitarian to arrest a man and detain him, when you cannot charge him with any offence against any written law - if that is not what we have always cried out against in Fascist states - then what is it?… If we are to survive as a free democracy, then we must be prepared, in principle, to concede to our enemies - even those who do not subscribe to our views - as much constitutional rights as you concede yourself."
"But we either believe in democracy or we don't. If we do, then, we must say categorically, without qualification, that no restraint from the any democratic processes, other than by the ordinary law of the land, should be allowed... If you believe in democracy, you must believe in it unconditionally. If you believe that men should be free, then, they should have the right of free association, of free speech, of free publication. Then, no law should permit those democratic processes to be set at nought, and no excuse, whether of security, should allow a government to be deterred from doing what it knows to be right, and what it must know to be right..."
"So when people say, 'Oh, ask the people!' It's childish rubbish. We are leaders. We know the consequences. You mean that ice-water man knows the consequences of his vote? They say people can think for themselves? Do you honestly believe that the chap who can't pass primary six knows the consequences of his choice when he answers a question viscerally on language, culture and religion?"
"But if you are a troublemaker... it's our job to politically destroy you. Put it this way. As long as JB Jeyaretnam [Workers' Party leader] stands for what he stands for -- a thoroughly destructive force for me -- we will knock him. There are two ways of playing this. One, a you attack the policies; two, you attack the system. Jeyaretnam was attacking the system, he brought the Chief Justice into it. If I want to fix you, do I need the Chief Justice to fix you? Everybody knows that in my bag I have a hatchet, and a very sharp one. You take me on, I take my hatchet, we meet in the cul-de-sac. That's the way I had to survive in the past. That's the way the communists tackled me. He brought the Chief Justice into the political arena."
"I started off believing all men were equal. I now know that's the most unlikely thing ever to have been, because millions of years have passed over evolution, people have scattered across the face of this earth, been isolated from each other, developed independently, had different intermixtures between races, peoples, climates, soils... I didn't start off with that knowledge. But by observation, reading, watching, arguing, asking, that is the conclusion I've come to."
"The Bell curve is a fact of life. The blacks on average score 85 per cent on IQ and it is accurate, nothing to do with culture. The whites score on average 100. Asians score more … the Bell curve authors put it at least 10 points higher. These are realities that, if you do not accept, will lead to frustration because you will be spending money on wrong assumptions and the results cannot follow."
"What people mean by consultation is an imitation of what they see in America; pressure groups and lobby groups..It's an unthinking adoption of Western practices of development without any pruning and modification to suit our circumstances."
"In scientific subjects, the natural remedy for dogmatism has been found in research. By temperament and training, the research worker is the antithesis of the pundit. What he is actively and constantly aware of is his ignorance, not his knowledge; the insufficiency of his concepts, of the terms and phrases in which he tries to excogitate his problems: not their final and exhaustive sufficiency. He is, therefore, usually only a good teacher for the few who wish to use their mind as a workshop, rather than a warehouse.*"
"To consult the statistician after an experiment is finished is often merely to ask him to conduct a post mortem examination. He can perhaps say what the experiment died of."
"The academic mind, as we know, is sometimes capable of assuming an aggressive attitude. The official mind, on the contrary, is and has to be, expert in the art of self-defence."
"Apart from sex linkage, we know almost nothing at present of linkage in man. Yet it is certain that every defect determined by a single factor must be located in one or other of twenty-three [sic] linkage groups. Each defect must therefore be linked in inheritance with numerous other observable traits, and with some of them is probably linked closely. The search for such linkage will certainly be lengthy, and at first, disappointing."
"(Coining phrase "null hypothesis") In relation to any experiment we may speak of this hypothesis as the “null hypothesis,” and it should be noted that the null hypothesis is never proved or established, but is possibly disproved, in the course of experimentation. Every experiment may be said to exist only in order to give the facts a chance of disproving the null hypothesis."
"The analysis of variance is not a mathematical theorem, but rather a convenient method of arranging the arithmetic."
"However, perhaps the main point is that you are under no obligation to analyse variance into its parts if it does not come apart easily, and its unwillingness to do so naturally indicates that one’s line of approach is not very fruitful."
"I believe that no one who is familiar, either with mathematical advances in other fields, or with the range of special biological conditions to be considered, would ever conceive that everything could be summed up in a single mathematical formula, however complex."
"Fairly large print is a real antidote to stiff reading."
"(Coining the phrase ‘test of significance’): Critical tests of this kind may be called tests of significance, and when such tests are available we may discover whether a second sample is or is not significantly different from the first."
"There is, then, in this analysis of variance no indication of any other than innate and heritable factors at work. (Coining of the phrase ‘analysis of variance’.)"
"I am genuinely sorry for scientists of the younger generation who never knew Fisher personally. So long as you avoided a handful of subjects like inverse probability that would turn Fisher in the briefest possible moment from extreme urbanity into a boiling cauldron of wrath, you got by with little worse than a thick head from the port which he loved to drink in the evening. And on the credit side you gained a cherished memory of English spoken in a Shakespearean style and delivered in the manner of a Spanish grandee."
"As a child, R. A. Fisher was fascinated by mathematics, statistics, and astronomy. His vision was severely impaired, but this was no impediment to his scholarship: He had tutors who would read mathematics to him, and young Fisher would picture the problems in his head. He eventually became so good at visualizing the solutions that he would frequently present his answers with absolutely no proof, saying that the solution was so obvious it didn’t need to be proven. Gosset remarked that these ‘obvious’ solutions to problems were generally not obvious to anyone else until they’d slogged through the math and could see on paper what Fisher saw in his head."
"This is perhaps the most important book on evolutionary genetics ever written."
"A book that I rate only second in importance in evolution theory to Darwin's Origin (this as joined with its supplement Of Man), and also rate as undoubtedly one of the greatest books of the twentieth century."
"He has made contributions to many areas of science; among them are agronomy, anthropology, astronomy, bacteriology, botany, economics, forestry, meteorology, psychology, public health, and-above all-genetics, in which he is recognized as one of the leaders. Out of this varied scientific research and his skill in mathematics, he has evolved systematic principles for the interpretation of empirical data; and he has founded a science of experimental design. On the foundations he has laid down, there has been erected a structure of statistical techniques that are used whenever people attempt to learn about nature from experiment and observation."
"A very able "manipulative" mathematician, Fisher enjoys a real mastery in evaluating complicated multiple integrals. In addition, he has a remarkable talent in the most difficult field of approaching problems of empirical research. As a result, his lifework includes a series of valuable contributions giving exact distributions of a variety of statistics, such as the correlation coefficient, the central χ2 with due allowance for degrees of freedom, the noncentral χ2, the quotient of two χ2, etc., etc."
"Before deciding anything I wrote to his tutor at Caius college... about his mathematical ability. The answer was that he could have been a first class mathematician had he "stuck to the ropes" but he would not... It took me a very short time to realize that he was more than a man of great ability, he was in fact a genius who must be retained."
"[...] the uncontrolled causes which may influence the result are always strictly innumerable."
"The million, million, million … to one chance happens once in a million, million, million … times no matter how surprised we may be that it results in us."
"More attention to the History of Science is needed, as much by scientists as by historians, and especially by biologists, and this should mean a deliberate attempt to understand the thoughts of the great masters of the past, to see in what circumstances or intellectual milieu their ideas were formed, where they took the wrong turning or stopped short on the right track."
"… the best causes tend to attract to their support the worst arguments, which seems to be equally true in the intellectual and in the moral sense."
"Faith Is Not Credulity."
"...it was Darwin’s chief contribution, not only to Biology but to the whole of natural science, to have brought to light a process by which contingencies a priori improbable, are given, in the process of time, an increasing probability, until it is their non-occurrence rather than their occurrence which becomes highly improbable. … Let the reader … attempt to calculate the prior probability that a hundred generations of his ancestry in the direct male line should each have left at least one son. The odds against such a contingency as it would have appeared to his hundredth ancestor (about the time of King Solomon) would require for their expression forty- four figures of the decimal notation; yet this improbable event has certainly happened."
"Natural selection is a mechanism for generating an exceedingly high degree of improbability."
"Available scientific knowledge provides a firm basis for believing that the groups of mankind differ in their innate capacity for intellectual and emotional development."
"… the so-called co-efficient of heritability, which I regard as one of those unfortunate short-cuts, which have often emerged in biometry for lack of a more thorough analysis of the data."
"After all, it is a common weakness of young authors to put too much into their papers."
"No, I cannot believe in the light of this speech that the reward of Lysenko's triumphant career is the advance of scientific knowledge; nor that it is the prosperity of poor peasants. The reward he is so eagerly grasping is Power, power for himself, power to threaten, power to torture, power to kill."
"He is an ambitious politician of a type likely to become prevalent in a system avowedly guided by a rigid ideology, who hopes to use the ideological dogmas to which he finds his colleagues committed as levers for his own advancement in the party and in the state."
"In organisms of all kinds the young are launched upon their careers endowed with a certain amount of biological capital derived from their parents. This varies enormously in amount in different species, but, in all, there has been, before the offspring is able to lead an independent existence, a certain expenditure of nutriment in addition, almost universally, to some expenditure of time or activity, which the parents are induced by their instincts to make for the advantage of their young. Let us consider the reproductive value of these offspring at the moment when this parental expenditure on their behalf has just ceased. If we consider the aggregate of an entire generation of such offspring it is clear that the total reproductive value of the males in this group is exactly equal to the total value of all the females, because each sex must supply half the ancestry of all future generations of the species. From this it follows that the sex ratio will so adjust itself, under the influence of Natural Selection, that the total parental expenditure incurred in respect of children of each sex, shall be equal; for if this were not so and the total expenditure incurred in producing males, for instance, were less than the total expenditure incurred in producing females, then since the total reproductive value of the males is equal to that of the females, it would follow that those parents, the innate tendencies of which caused them to produce males in excess, would, for the same expenditure, produce a greater amount of reproductive value; and in consequence would be the progenitors of a larger fraction of future generations than would parents having a congenital bias towards the production of females. Selection would thus raise the sex-ratio until the expenditure upon males became equal to that upon females."
"[We are now] in a position to judge of the validity of the objection which has been made, that the principle of Natural Selection depends on a succession of favourable chances. The objection is more in the nature of an innuendo than of a criticism, for it depends for its force upon the ambiguity of the word chance, in its popular uses. The income derived from a Casino by its proprietor may, in one sense, be said to depend upon a succession of favourable chances, although the phrase contains a suggestion of improbability more appropriate to the hopes of the patrons of his establishment. It is easy without any very profound logical analysis to perceive the difference between a succession of favourable deviations from the laws of chance, and on the other hand, the continuous and cumulative action of these laws. It is on the latter that the principle of Natural Selection relies."
"Professor Eddington has recently remarked that 'The law that entropy always increases — the second law of thermodynamics — holds, I think, the supreme position among the laws of nature'. It is not a little instructive that so similar a law [the fundamental theorem of natural selection] should hold the supreme position among the biological sciences."
"We may consequently state the fundamental theorem of Natural Selection in the form : The rate of increase in fitness of any organism at any time is equal to its genetic variance in fitness at that time."
"No efforts of mine could avail to make the book easy reading."
"No practical biologist interested in sexual reproduction would be led to work out the detailed consequences experienced by organisms having three or more sexes; yet what else should he do if he wishes to understand why the sexes are, in fact, always two?"
"Natural Selection is not evolution."
"The German government has taken energetic measures against the propagation of the defective, the mentally diseased, and the criminal. The ideal solution would be the suppression of each of these individuals as soon as he has proven himself to be dangerous."
"L'intelligence est presque inutile à celui qui ne possède qu'elle."
"The progress of the strong depends on the conditions of their development and the possibility left to parents of transmitting to their offspring the qualities which they have acquired in the course of their existence. Modern society must, therefore, allow to all a certain stability of life, a home, a garden, some friends. Children must be reared in contact with things which are the expression of the mind of their parents. It is imperative to stop the transformation of the farmer, the artisan, the artist, the professor, and the man of science into manual or intellectual proletarians, possessing nothing but their hands or their brains. The development of this proletariat will be the everlasting shame of industrial civilization. It has contributed to the disappearance of the family as a social unit, and to the weakening of intelligence and moral sense. It is destroying the remains of culture. All forms of the proletariat must be suppressed. Each individual should have the security and the stability required for the foundation of a family. Marriage must cease being only a temporary union. The union of man and woman, like that of the higher anthropoids, ought to last at least until the young have no further need of protection. The laws relating to education, and especially to that of girls, to marriage, and divorce should, above all, take into account the interest of children. Women should receive a higher education, not in order to become doctors, lawyers, or professors, but to rear their offspring to be valuable human beings. The free practice of eugenics could lead not only to the development of stronger individuals, but also of strains endowed with more endurance, intelligence, and courage. These strains should constitute an aristocracy, from which great men would probably appear. Modern society must promote, by all possible means, the formation of better human stock. No financial or moral rewards should be too great for those who, through the wisdom of their marriage, would engender geniuses. The complexity of our civilization is immense. No one can master all its mechanisms. However, these mechanisms have to be mastered. There is need today of men of larger mental and moral size, capable of accomplishing such a task. The establishment of a hereditary biological aristocracy through voluntary eugenics would be an important step toward the solution of our present problems."
"We have mentioned that natural selection has not played its part for a long while. That many inferior individuals have been conserved through the efforts of hygiene and medicine. But we cannot prevent the reproduction of the weak when they are neither insane nor criminal. Or destroy sickly or defective children as we do the weaklings in a litter of puppies. The only way to obviate the disastrous predominance of the weak is to develop the strong. Our efforts to render normal the unfit are evidently useless. We should, then, turn our attention toward promoting the optimum growth of the fit. By making the strong still stronger, we could effectively help the weak; For the herd always profits by the ideas and inventions of the elite. Instead of leveling organic and mental inequalities, we should amplify them and construct greater men."
"We must single out the children who are endowed with high potentialities, and develop them as completely as possible. And in this manner give to the nation a non-hereditary aristocracy. Such children may be found in all classes of society, although distinguished men appear more frequently in distinguished families than in others. The descendants of the founders of American civilization may still possess the ancestral qualities. These qualities are generally hidden under the cloak of degeneration. But this degeneration is often superficial. It comes chiefly from education, idleness, lack of responsibility and moral discipline. The sons of very rich men, like those of criminals, should be removed while still infants from their natural surroundings. Thus separated from their family, they could manifest their hereditary strength. In the aristocratic families of Europe there are also individuals of great vitality. The issue of the Crusaders is by no means extinct. The laws of genetics indicate the probability that the legendary audacity and love of adventure can appear again in the lineage of the feudal lords. It is possible also that the offspring of the great criminals who had imagination, courage, and judgment, of the heroes of the French or Russian Revolutions, of the high-handed business men who live among us, might be excellent building stones for an enterprising minority. As we know, criminality is not hereditary if not united with feeble-mindedness or other mental or cerebral defects. High potentialities are rarely encountered in the sons of honest, intelligent, hard-working men who have had ill luck in their careers, who have failed in business or have muddled along all their lives in inferior positions. Or among peasants living on the same spot for centuries. However, from such people sometimes spring artists, poets, adventurers, saints. A brilliantly gifted and well-known New York family came from peasants who cultivated their farm in the south of France from the time of Charlemagne to that of Napoleon."
"[M]en cannot follow modern civilization along its present course, because they are degenerating. They have been fascinated by the beauty of the sciences of inert matter. They have not understood that their body and consciousness are subjected to natural laws, more obscure than, but as inexorable as, the laws of the sidereal world. Neither have they understood that they cannot transgress these laws without being punished. They must, therefore, learn the necessary relations of the cosmic universe, of their fellow men, and of their inner selves, and also those of their tissues and their mind. Indeed, man stands above all things. Should he degenerate, the beauty of civilization, and even the grandeur of the physical universe, would vanish. ... Humanity's attention must turn from the machines of the world of inanimate matter to the body and the soul of man, to the organic and mental processes which have created the machines and the universe of Newton and Einstein"
