“The very desire for guarantees that our values are eternal and secure in some objective heaven is perhaps only a craving for the certainties of childhood or the absolute values of our primitive past.”

“Mathematics, from the earliest times to which the history of human reason can reach, has followed, among that wonderful people of the Greeks, the safe way of science. But it must not be supposed that it was as easy for mathematics as for logic, in which reason is concerned with itself alone, to find, or rather to make for itself that royal road. I believe, on the contrary, that there was a long period of tentative work (chiefly still among the Egyptians), and that the change is to be ascribed to a revolution, produced by the happy thought of a single man, whose experiments pointed unmistakably to the path that had to be followed, and opened and traced out for the most distant times the safe way of a science. The history of that intellectual revolution, which was far more important than the passage round the celebrated Cape of Good Hope, and the name of its fortunate author, have not been preserved to us. … A new light flashed on the first man who demonstrated the properties of the isosceles triangle (whether his name was Thales or any other name), for he found that he had not to investigate what he saw hi the figure, or the mere concepts of that figure, and thus to learn its properties; but that he had to produce (by construction) what he had himself, according to concepts a priori, placed into that figure and represented in it, so that, in order to know anything with certainty a priori, he must not attribute to that figure anything beyond what necessarily follows from what he has himself placed into it, in accordance with the concept.”

“This statement appears to us to be conclusive with respect to the insufficiency of the undulatory theory, in its present state, for explaining all the phenomena of light. But we are not therefore by any means persuaded of the perfect sufficiency of the projectile system: and all the satisfaction that we have derived from an attentive consideration of the accumulated evidence, which has been brought forward, within the last ten years, on both sides of the question, is that of being convinced that much more evidence is still wanting before it can be positively decided. In the progress of scientific investigation, we must frequently travel by rugged paths, and through valleys as well as over mountains. Doubt must necessarily succeed often to apparent certainty, and must again give place to a certainty of a higher order; such is the imperfection of our faculties, that the descent from conviction to hesitation is not uncommonly as salutary, as the more agreeable elevation from uncertainty to demonstration. An example of such alternations may easily be adduced from the history of chemistry. How universally had phlogiston once expelled the aërial acid of Hooke and Mayow. How much more completely had phlogiston given way to oxygen! And how much have some of our best chemists been lately inclined to restore the same phlogiston to its lost honours! although now again they are beginning to apprehend that they have already done too much in its favour. In the mean time, the true science of chemistry, as the most positive dogmatist will not hesitate to allow, has been very rapidly advancing towards ultimate perfection.”

“I don't think it's healthy for people to want there to be a permanent, unalterable, irremovable authority over them. I don't like the idea of a father who never goes away, the idea of a king who cannot be deposed, the idea of a judge who doesn't allow a lawyer or a jury or an appeal. This is an appeal to absolutism. It's the part of ourselves that's not so nice; that wants security, that wants certainty, that wants to be taken care of. For hundreds and hundreds of years, the human struggle for freedom was against the worst kind of dictatorship of all: the theocracy, the one that claims it has God on its side. I believe that totalitarian temptation has to be resisted. What I'm inviting you to do is to consider emancipating yourselves from the idea that you, selfishly, are the sole object of all the wonders of the cosmos and of nature - because that's not a humble idea at all, it's a very arrogant one and there's no evidence for it. And then, again, the second emancipation - to think of yourselves as free citizens who are not enthralled to any supernatural-eternal authority; which you will always find is interpreted for you by other mammals who claim to have access to this authority - that gives them special power over you. Don't allow yourselves to have your lives run like that.”

“I shall now no more behold my dear father with these "bodily eyes. With him a whole threescore and ten years of the past has doubly died for me. It is as if a new leaf in the great hook of time were turned over. Strange time — endless time or of which I see neither end nor beginning. All rushes on. Man follows man. His life is as a tale that has been told; yet under Time does there not lie Eternity? Perhaps my father, all that essentially was my father, is even now near me, with me. Both he and I are with God. Perhaps, if it so please God, we shall in some higher state of being meet one another, recognize one another. As it is written. We shall be forever with God. The possibility, nay (in some way), the certainty, of perennial existence daily grows plainer to me. "The essence of whatever was, is, or shall be, even now is." God is great. God is good. His will be done, for it will be right. As it is, I can think peaceably of the departed love. All that was earthly, harsh, sinful, in our relation has fallen away; all that was holy in it remains. I can see my dear father's life in some measure as the sunk pillar on which mine was to rise and be built; the waters of time have now swelled up round his (as they will round mine); I can see it all transfigured, though I touch it no longer. I might almost say his spirit seems to have entered into me (so clearly do I discern and love him); I seem to myself only the continuation and second volume of my father. These days that I have spent thinking of him and of his end are the peaceablest, the only Sabbath that I have had in London. One other of the universal destinies of man has overtaken me. Thank Heaven, I know, and have known, what it is to be a son; to love a father, as spirit can love spirit. God give me to live to my father's honor and to His. And now, beloved father, farewell for the last time in this world of shadows I In the world of realities may the Great Father again bring us together in perfect holiness and perfect love! Amen!”

“The anti‐Semite has chosen hate because hate is a faith; at the outset he has chosen to devaluate words and reasons. How entirely at ease he feels as a result. How futile and frivolous discussions about the rights of the Jew appear to him. He has placed himself on other ground from the beginning. If out of courtesy he consents for a moment to defend his point of view, he lends himself but does not give himself. He tries simply to project his intuitive certainty onto the plane of discourse. I mentioned awhile back some remarks by anti‐Semites, all of them absurd: "I hate Jews because they make servants insubordinate, because a Jewish furrier robbed me, etc." Never believe that anti‐ Semites are completely unaware of the absurdity of their replies. They know that their remarks are frivolous, open to challenge. But they are amusing themselves, for it is their adversary who is obliged to use words responsibly, since he believes in words. The anti‐Semites have the right to play. They even like to play with discourse for, by giving ridiculous reasons, they discredit the seriousness of their interlocutors. They delight in acting in bad faith, since they seek not to persuade by sound argument but to intimidate and disconcert. If you press them too closely, they will abruptly fall silent, loftily indicating by some phrase that the time for argument is past. It is not that they are afraid of being convinced. They fear only to appear ridiculous or to prejudice by their embarrassment their hope of winning over some third person to their side.”

“A finished or even a competent reasoner is not the work of nature alone… education develops faculties which would otherwise never have manifested their existence. It is, therefore, as necessary to learn to reason before we can expect to be able to reason, as it is to learn to swim or fence, in order to attain either of those arts. Now, something must be reasoned upon, it matters not much what it is, provided that it can be reasoned upon with certainty. The properties of mind or matter, or the study of languages, mathematics, or natural history may be chosen for this purpose. Now, of all these, it is desirable to choose the one… in which we can find out by other means, such as measurement and ocular demonstration of all sorts, whether the results are true or not.
.. Now the mathematics are peculiarly well adapted for this purpose, on the following grounds:—
1. Every term is distinctly explained, and has but one meaning, and it is rarely that two words are employed to mean the same thing.
2. The first principles are self-evident, and, though derived from observation, do not require more of it than has been made by children in general.
3. The demonstration is strictly logical, taking nothing for granted except the self-evident first principles, resting nothing upon probability, and entirely independent of authority and opinion.
4. When the conclusion is attained by reasoning, its truth or falsehood can be ascertained, in geometry by actual measurement, in algebra by common arithmetical calculation. This gives confidence, and is absolutely necessary, if… reason is not to be the instructor, but the pupil.
5. There are no words whose meanings are so much alike that the ideas which they stand for may be confounded.
…These are the principal grounds on which… the utility of mathematical studies may be shewn to rest, as a discipline for the reasoning powers. But the habits of mind which these studies have a tendency to form are valuable in the highest degree. The most important of all is the power of concentrating the ideas which a successful study of them increases where it did exist, and creates where it did not. A difficult position or a new method of passing from one proposition to another, arrests all the attention, and forces the united faculties to use their utmost exertions. The habit of mind thus formed soon extends itself to other pursuits, and is beneficially felt in all the business of life.”

“The denial of becoming by physics estranged science from philosophy… [and] became a dogmatic assertion directed against all those (chemists, biologists, physicians) for whom a qualitative diversity existed in nature… Today we believe that the epoch of certainties and absolute oppositions is over. Physicists belong to their culture, to which, in their turn, they make an essential contribution.”

“Gradually we began [ De Stijl-artists in The Netherlands, 1918] to present a closed front. By working there had been created not only a clarity in the collective consciousness of our group, but we had gained a certainty, which made it possible for us to define our collective attitude towards life and to perpetrate it according to the requirements of the period... As the world war [ World War I ] was coming to an end, we all came to feel the need of securing an interest in our efforts beyond the narrow boundaries of Holland.”

“There were many reasons why we did not gain complete success at Arnhem. The following in my view were the main ones. First. The operation was not regarded at Supreme Headquarters as the spearhead of a major Allied movement on the northern flank designed to isolate, and finally to occupy, the Ruhr - the one objective in the West which the Germans could not afford to lose. There is no doubt in my mind that Eisenhower always wanted to give priority to the northern thrust and to scale down the southern one. He ordered this to be done, and he thought that it was being done. It was not being done. Second. The airborne forces at Arnhem were dropped too far away from the vital objective - the bridge. It was some hours before they reached it. I take the blame for this mistake. I should have ordered Second Army and 1st Airborne Corps to arrange that at least one complete Parachute Brigade was dropped quite close to the bridge, so that it could have been captured in a matter of minutes and its defence soundly organised with time to spare. I did not do so. Third. The weather. This turned against us after the first day and we could not carry out much of the later airborne programme. But weather is always an uncertain factor, in war and in peace. This uncertainty we all accepted. It could only have been offset, and the operation made a certainty, by allotting additional resources to the project, so that it became an Allied and not merely a British project. Fourth. The 2nd S. S. Panzer Corps was refitting in the Arnhem area, having limped up there after its mauling in Normandy. We knew it was there. But we were wrong in supposing that it could not fight effectively; its battle state was far beyond our expectation. It was quickly brought into action against the 1st Airborne Division.”

“Yeah. ‘Environment’ was very big for a while. Ecology Now stickers on the windshields of cars belonging to hairy young men—cars which dripped oil wherever they parked and took off in clouds of smoke thicker than your pipe can produce…Before long, the fashionable cause was something else, I forget what. Anyhow, that whole phase—the wave after wave of causes—passed away. People completely stopped caring…
I feel a moral certainty that a large part of the disaster grew from this particular country, the world’s most powerful, the vanguard country for things both good and ill…never really trying to meet the responsibilities of power.
We’ll make halfhearted attempts to stop some enemies in Asia, and because the attempts are halfhearted we’ll piss away human lives—on both sides—and treasure—to no purpose. Hoping to placate the implacable, we’ll estrange our last few friends. Men elected to national office will solemnly identify inflation with rising prices, which is like identifying red spots with the measles virus, and slap on wage and price controls, which is like papering the cracks in a house whose foundations are sliding away. So economic collapse brings international impotence…As for our foolish little attempts to balance what we drain from the environment against what we put back—well, I mentioned that car carrying the ecology sticker.
At first Americans will go on an orgy of guilt. Later they’ll feel inadequate. Finally they’ll turn apathetic. After all, they’ll be able to buy any anodyne, any pseudo-existence they want.”

“Now the salient characteristic of the decision tools employed in management science is that they have to be capable of actually making or recommending decisions, taking as their inputs the kinds of empirical data that are available in the real world, and performing only such computations as can reasonably be performed by existing desk calculators or, a little later electronic computers. For these domains, idealized models of optimizing entrepreneurs, equipped with complete certainty about the world - or, a worst, having full probability distributions for uncertain events - are of little use. Models have to be fashioned with an eye to practical computability, no matter how severe the approximations and simplifications that are thereby imposed on them…
The first is to retain optimization, but to simplify sufficiently so that the optimum (in the simplified world!) is computable. The second is to construct satisficing models that provide good enough decisions with reasonable costs of computation. By giving up optimization, a richer set of properties of the real world can be retained in the models… Neither approach, in general, dominates the other, and both have continued to co-exist in the world of management science.”
