Agronomists

"It is far from easy to determine whether she [Nature] has proved to man a kind parent or a merciless stepmother."

"Haec est Italia diis sacra"

"Everything is soothed by oil, and this is the reason why divers send out small quantities of it from their mouths, because it smooths every part which is rough."

"It is ridiculous to suppose that the great head of things, whatever it be, pays any regard to human affairs."

"The only certainty is that nothing is certain. (Fuller version: This series of instances entangles unforeseeing mortality, so that among these things but one thing is in the least certain—that nothing certain exists, and that nothing is more pitiable, or more presnmptuous, than man! In Latin: Quae singula inprovidam mortalitatem involvunt, solum ut inter ista vel certu(m) sit nihil esse certi nec quicquam miserius homine aut superbius. Some sources have "certu", others "certum".)"

"The world, and whatever that be which we call the heavens, by the vault of which all things are enclosed, we must conceive to be a deity, to be eternal, without bounds, neither created nor subject at any time to destruction. To inquire what is beyond it is no concern of man; nor can the human mind form any conjecture concerning it."

"In comparing various authors with one another, I have discovered that some of the gravest and latest writers have transcribed, word for word, from former works, without making acknowledgment."

"From the days of Father Bacchus to Alexander the Great, their kings are reckoned at 154, whose reigns extend over 6451 years and 3 months."

"Fortes Fortuna iuvat."

"Indeed, what is there that does not appear marvelous when it comes to our knowledge for the first time? How many things, too, are looked upon as quite impossible until they have actually been effected?"

"With man, most of his misfortunes are occasioned by man."

"Man is the only one that knows nothing, that can learn nothing without being taught. He can neither speak nor walk nor eat, and in short he can do nothing at the prompting of nature only, but weep."

"To laugh, if but for an instant only, has never been granted to man before the fortieth day from his birth, and then it is looked upon as a miracle of precocity."

"Did not Mister Godbout himself – I will surprise many, such a bad historical reputation was made about him – propose in 1948, in all letters, the holding of a referendum to reach [...], let us get ready, "an equal to equal agreement between Quebec and Canada"? It was 32 years ago..."

"Posterity, until now, has been truly inequitable regarding Godbout. It is true, he was responsible [...] of renunciations, if you will, renunciations that this absolutely infernal pressure of wartime made probably inevitable. But it is quite unjust that people forgot that these few years of the Godbout government were also punctuated by three crucial decisions that almost constitute the act of birth of contemporary Quebec. In a few brief years, in only one government mandate, the creation of Hydro-Quebec, the establishment of obligatory instruction and [...] the women's vote."

"Some of the environmental lobbyists of the western nations are the salt of the earth, but many of them are elitists. They have never experienced the physical sensation of hunger. They do their lobbying from comfortable office suites in Washington or Brussels. If they lived just one month amid the misery of the developing world, as I have for fifty years, they would be crying out for tractors, and fertilizer, and irrigation canals, and be outraged that fashionable elitists back home were trying to deny them these things."

"I now say that the world has the technology – either available or well advanced in the research pipeline – to feed on a sustainable basis a population of 10 billion people. The more pertinent question today is whether farmers and ranchers will be permitted to use this new technology? While the affluent nations can certainly afford to adopt ultra low-risk positions, and pay more for food produced by the so-called “organic” methods, the one billion chronically undernourished people of the low income, food-deficit nations cannot."

"It is a sad fact that on this earth at this late date there are still two worlds, "the privileged world" and "the forgotten world". The privileged world consists of the affluent, developed nations, comprising twenty-five to thirty percent of the world population, in which most of the people live in a luxury never before experienced by man outside the Garden of Eden. The forgotten world is made up primarily of the developing nations, where most of the people, comprising more than fifty percent of the total world population, live in poverty, with hunger as a constant companion and fear of famine a continual menace."

"There can be no permanent progress in the battle against hunger until the agencies that fight for increased food production and those that fight for population control unite in a common effort."

"Some credit him with saving more human lives than any other person in history."

"You can't build a peaceful world on empty stomachs and human misery."

"If people want to believe that the organic food has better nutritive value, it's up to them to make that foolish decision. But there's absolutely no research that shows that organic foods provide better nutrition. As far as plants are concerned, they can't tell whether that nitrate ion comes from artificial chemicals or from decomposed organic matter. If some consumers believe that it's better from the point of view of their health to have organic food, God bless them. Let them buy it. Let them pay a bit more. It's a free society. But don't tell the world that we can feed the present population without chemical fertilizer. That's when this misinformation becomes destructive."

"That's ridiculous. This shouldn't even be a debate. Even if you could use all the organic material that you have--the animal manures, the human waste, the plant residues--and get them back on the soil, you couldn't feed more than 4 billion people. In addition, if all agriculture were organic, you would have to increase cropland area dramatically, spreading out into marginal areas and cutting down millions of acres of forests. At the present time, approximately 80 million tons of nitrogen nutrients are utilized each year. If you tried to produce this nitrogen organically, you would require an additional 5 or 6 billion head of cattle to supply the manure. How much wild land would you have to sacrifice just to produce the forage for these cows? There's a lot of nonsense going on here."

"(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."

"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."
