“Though the principles of the banking trade may appear somewhat abstruse, the practice is capable of being reduced to strict rules. To depart upon any occasion from these rules, in consequence of some flattering speculation of extraordinary gain, is almost always extremely dangerous, and frequently fatal to the banking company which attempts it.”

“Around 1958, I became aware of H. A. Simon's seminal papers on bounded rationality and was immediately convinced by his arguments. I tried to construct a theory of boundedly rational multigoal decision making. Together with Heinz Sauermann, I worked out an "aspiration adaptation theory of the firm" which was published as a journal article in 1962… More and more I came to the conclusion that purely speculative approaches like that of our paper of 1962 are of limited value. The structure of boundedly rational economic behavior cannot be invented in the armchair, it must be explored experimentally.”

“I dare truly and boldly say, that one years exercise therein to ingenious spirits, under able Masters, will produce more real and true fruit, than the studying Aristotelian Philosophy hath brought forth in many centuries. O that the Schools therefore would leave their idle, and fruitless speculations, and not be too proud to put their hands to the coals and furnace, where they might find ocular experiments to confute their fopperies, and produce effects that would be beneficial to all posterities.”

“There is no methodological process by which one can confirm the existence of an object independent of the confirmatory process involving oneself. The outside is a void, there is only the inside.

“Some researchers have speculated that religion itself may have played an important role in getting large groups of prehistoric humans to socially cohere. If this is true, we can say that religion has served an important purpose. This does not suggest, however, that it serves an important purpose now. There is, after all, nothing more natural than rape. But no one would argue that rape is good, or compatible with a civil society, because it may have had evolutionary advantages for our ancestors. That religion may have served some necessary function for us in the past does not preclude the possibility that it is now the greatest impediment to our building a global civilization.”

“The clash between reason and Portuguese experience. Hooykaas' starting point is the intellectual challenge which, from the early 15th century onward, was posed by the discoveries of the Portuguese mariners… There follows an array of fascinating accounts of, and quotations from, works by contemporary authors who were compelled to face as facts numerous phenomena the ancients had been quite sure could not possibly be observed because they were bound not to exist. Examples are Aristotle's denial that the tropics could be inhabited; Ptolemy's mathematically derived conviction that all dry land is confined to part of the Northern Hemisphere, and so on. …In Hooykaas' view we are witnessing here a birth of 'natural history' in the domain of the hard and given fact… The narrow world of sense-data to which the ancient natural philosophers had confined their all-too-rational speculations was now being blown to pieces. And this was not being done by fellow natural philosophers, but rather at the urging of scarcely literate sailors!”

“When a person tries to act in accordance with his conscience, when he tries to speak the truth, when he tries to behave like a citizen, even in conditions where citizenship is degraded, it won't necessarily lead anywhere, but it might.

Life is an action — not a thought. And the penalty paid by him who speculates on truth, is that by degrees the very truth he holds becomes a falsehood.”

“Throughout the nineteenth century, apart from the division in theoretical sciences and arts, classifiers attempted to divide the sciences into two groups. Already they had before them the examples of Francis Bacon (speculative and descriptive) and Hobbes (quantitative and qualitative). For Coleridge, the sciences were either pure (Grammar, Logic, Rhetoric, Mathematics, Metaphysics) or mixed. Arthur Schopenhauer’s similar groups were called pure and empirical, Wilhelm Wundt in 1887 called them formal and empirical, Globot mathematical and theoretical, and the St. Louis Congress of Arts and Sciences (1904) normative and physical.”

“But it never occurred to him to want to be a philosopher, or dedicate himself to Speculation; he was still too fickle for that. True, he was not drawn now to one thing and now to another – thinking was and remained his passion – but he still lacked the self-discipline required for acquiring a deeper coherence. Both the significant and the insignificant attracted him equally as points of departure for his pursuits; the result was not of great consequence – only the movements of thought as such interested him. Sometimes he noticed that he reached one and the same conclusion from quite different starting points, but this did not in any deeper sense engage his attention. His delight was always just to be pressing on; wherever he suspected a labyrinth, he had to find the way. Once he had started, nothing could bring him to a halt. If he found the going difficult and became tired of it before he ought, he would adopt a very simple remedy – he would shut himself up in his room, make everything as festive as possible, and then say loudly and clearly: I will do it. He had learned from his father that one can do what one wills, and his father’s life had not discredited this theory. Experiencing this had given Johannes indescribable pride; that there could be something one could not do when one willed it was unbearable to him. But his pride did not in the least indicate weakness of will, for when he had uttered these energetic words he was ready for anything; he then had a still higher goal – to penetrate the intricacies of the problem by force of will. This again was an adventure that inspired him. Indeed his life was in this way always adventurous. He needed no woods and wanderings for his adventures, but only what he possessed – a little room with one window.”

“MR. PANSCOPE. (suddenly emerging from a deep reverie.) I have heard, with the most profound attention, everything which the gentleman on the other side of the table has thought proper to advance on the subject of human deterioration; and I must take the liberty to remark, that it augurs a very considerable degree of presumption in any individual, to set himself up against the authority of so many great men, as may be marshalled in metaphysical phalanx under the opposite banners of the controversy; such as Aristotle, Plato, the scholiast on Aristophanes, St Chrysostom, St Jerome, St Athanasius, Orpheus, Pindar, Simonides, Gronovius, Hemsterhusius, Longinus, Sir Isaac Newton, Thomas Paine, Doctor Paley, the King of Prussia, the King of Poland, Cicero, Monsieur Gautier, Hippocrates, Machiavelli, Milton, Colley Cibber, Bojardo, Gregory Nazianzenus, Locke, D'Alembert, Boccaccio, Daniel Defoe, Erasmus, Doctor Smollett, Zimmermann, Solomon, Confucius, Zoroaster, and Thomas-a-Kempis.
MR. ESCOT. I presume, sir, you are one of those who value an authority more than a reason.
MR. PANSCOPE. The authority, sir, of all these great men, whose works, as well as the whole of the Encyclopaedia Britannica, the entire series of the Monthly Review, the complete set of the Variorum Classics, and the Memoirs of the Academy of Inscriptions, I have read through from beginning to end, deposes, with irrefragable refutation, against your ratiocinative speculations, wherein you seem desirous, by the futile process of analytical dialectics, to subvert the pyramidal structure of synthetically deduced opinions, which have withstood the secular revolutions of physiological disquisition, and which I maintain to be transcendentally self-evident, categorically certain, and syllogistically demonstrable.
SQUIRE HEADLONG. Bravo! Pass the bottle. The very best speech that ever was made.
MR. ESCOT. It has only the slight disadvantage of being unintelligible.
MR. PANSCOPE. I am not obliged, Sir, as Dr Johnson remarked on a similar occasion, to furnish you with an understanding.
MR. ESCOT. I fear, Sir, you would have some difficulty in furnishing me with such an article from your own stock.
MR. PANSCOPE. 'Sdeath, Sir, do you question my understanding?
MR. ESCOT. I only question, Sir, where I expect a reply, which from what manifestly has no existence, I am not visionary enough to anticipate.
MR. PANSCOPE. I beg leave to observe, sir, that my language was perfectly perspicuous, and etymologically correct; and, I conceive, I have demonstrated what I shall now take the liberty to say in plain terms, that all your opinions are extremely absurd.
MR. ESCOT. I should be sorry, sir, to advance any opinion that you would not think absurd.
MR. PANSCOPE. Death and fury, Sir!
MR. ESCOT. Say no more, Sir - that apology is quite sufficient.
MR. PANSCOPE. Apology, Sir?
MR. ESCOT. Even so, Sir. You have lost your temper, which I consider equivalent to a confession that you have the worst of the argument.

Matter, too, has life; it is energy solidified. Our bodies are like prisons, and I look forward to be free, but I don't speculate on what will happen to me.

In the midst of his outpouring of anger at and dismissal of Goldschmidt, Dobzhansky neglected to consider the fact that while Goldschmidt's systemic mutations may not have been observed, neither had the mechanisms of speculation that he, or anyone else, for that matter, had proposed. …it was and still is the case that, with the exception of Dobzhansky's claim about a new species of fruit fly, the formation of a new species, by any mechanism, has never been observed.”

“Thus, the founders of grammar were Sîbawayh and, after him, al-Fârisî and Az-Zajjâj. All of them were of non-Arab (Persian) descent. They were brought up in the Arabic language and acquired the knowledge of it through their upbringing and through contact with Arabs. They invented the rules of (grammar) and made it into a discipline (in its own right) for later (generations to use). Most of the ḥadîth scholars who preserved traditions for the Muslims also were Persians, or Persian in language and upbringing, because the discipline was widely cultivated in the 'Irâq and the regions beyond. Furthermore all the scholars who worked in the science of the principles of jurisprudence were Persians. The same applies to speculative theologians and to most Qur'ân commentators. Only the Persians engaged in the task of preserving knowledge and writing systematic scholarly works. Thus, the truth of the following statement by the Prophet becomes apparent: 'If scholarship hung suspended in the highest parts of heaven, the Persians would attain it.”

“Suppose I think, after doing my accounts, that I have a large balance at the bank. And suppose you want to find out whether this belief of mine is “wishful thinking.” You can never come to any conclusion by examining my psychological condition. Your only chance of finding out is to sit down and work through the sum yourself. When you have checked my figures, then, and then only, will you know whether I have that balance or not. If you find my arithmetic correct, then no amount of vapouring about my psychological condition can be anything but a waste of time. If you find my arithmetic wrong, then it may be relevant to explain psychologically how I came to be so bad at my arithmetic, and the doctrine of the concealed wish will become relevant—but only after you have yourself done the sum and discovered me to be wrong on purely arithmetical grounds. It is the same with all thinking and all systems of thought. If you try to find out which are tainted by speculating about the wishes of the thinkers, you are merely making a fool of yourself. You must first find out on purely logical grounds which of them do, in fact, break down as arguments. Afterwards, if you like, go on and discover the psychological causes of the error.”

“Had Mr. Darwin written a work on the change of species, as determined by observation and experiment, without any other object but that of advancing natural science, he would have obtained a high place among philosophical naturalists. But after reading his work in which the name of the Creator is never distinctly mentioned, we can hardly believe that scientific truth was the only object the author had in view. Researches, conducted under the influence of other motives, are not likely to stand the test of a rigorous scrutiny; and some of Mr. Darwin's not unfriendly critics have produced ample evidence that the idol of speculation has been occasionally worshipped at the expense of truth.”

“Early scientific thinking was holistic, but speculative -- the modern scientific temper reacted by being empirical, but atomistic. Neither is free from error, the former because it replaces factual inquiry with faith and insight, and the latter because it sacrifices coherence at the altar of facticity. We witness today another shift in ways of thinking: the shift toward rigorous but holistic theories. This means thinking in terms of facts and events in the context of wholes, forming integrated sets with their own properties and relationships”

Our genetic makeup permits a wide range of behaviors—from Ebenezer Scrooge before to Ebenezer Scrooge after. I do not believe that the miser hoards through opportunist genes or that the philanthropist gives because nature endowed him with more than the normal complement of altruist genes. Upbringing, culture, class, status, and all the intangibles that we call “free will,” determine how we restrict our behaviors from the wide spectrum—extreme altruism to extreme selfishness—that our genes permit.”

“There was a time when philosophy might have been defined as the science of human activity, so all-comprehensive was it. The ambitious Greek who would attach his name to a philosophical system must include in his scheme all that could be known, done, and speculated about God, the world, and man. In the course of time and the specialization of the sciences this view of philosophy fell away, and was replaced by the more exact and narrower conception of modern times.”

“… a rather different class of applications of the idea of best allocation of scarce resources… usually referred to as the theory of optimal economic growth. In most studies of this kind made in the countries with market economies there is not an identifiable client to whom the findings are submitted as policy recommendations. Nor is there an obvious choice of objective function, such as cost minimization or profit maximization in the studies addressed to individual enterprises. The field has more of a speculative character. The models studied usually contain only a few highly aggregated variables. One considers alternative objective functions that incorporate or emphasize various strands of ethical, political, or social thought. These objectives are then tried out to see what future paths of the economy they imply under equally simplified assumptions of technology or resource availability.”

“The landscape problem represents a serious problem in the development of science. Its solution requires… the construction of speculative cosmological scenarios, which posit regions or epochs of our universe for which we presently have no observable evidence. Nonetheless we must insist on taking seriously only scenarios and hypotheses that make falsifiable or strongly verifiable predictions, otherwise people can just make stuff up and the distinction between science and mythology becomes porous. …there are already candidate solutions that make real, falsifiable predictions.”

“When scientists need to explain difficult points of theory, illustration by hypothetical example - rather than by total abstraction - works well (perhaps indispensably) as a rhetorical device. Such cases do not function as speculations in the pejorative sense - as silly stories that provide insight into complex mechanisms - but rather as idealized illustrations to exemplify a difficult point of theory. (Other fields, like philosophy and the law, use such conjectural cases as a standard device.)”

“If you ask most teachers of science what their main goal is, they will probably say: for my students to understand the basic concepts of physics, chemistry, biology, or whatever other field is being studied. The critical words here are ‘understand’ and ‘concept’, and both of these terms assume a fundamentally psychological approach to learning… If we see the goals of science education in terms of what students will be able to do, and how they will be able to make sense of the world, rather than in terms of our speculations about what may be going on in their brains, then we need to see scientific learning as the acquisition of cultural tools and practices, as learning to participate in very specific and often specialized forms of human activity”

“The climax was reached when the same Marxist professors started explaining away Islamic iconoclasm in terms of what they described as Hindu destruction of Buddhist and Jain places of worship. They have never been able to cite more than half-a-dozen cases of doubtful veracity. A few passages in Sanskrit literature coupled with speculations about some archaeological sites have sufficed for floating the story, sold ad nauseam in the popular press, that Hindus destroyed Buddhist and Jain temples on a large scale. Half-a-dozen have become thousands and then hundreds of thousands in the frenzied imagination suffering from a deep-seated anti-Hindu animus…. And these “facts” have been presented with a large dose of suppressio veri suggestio falsi…. A very late Buddhist book from Sri Lanka accuses Pushyamitra Sunga, a second century B. C. king, of offering prizes to those who brought to him heads of Buddhist monks. This single reference has sufficed for presenting Pushyamitra as the harbinger of a “Brahmanical reaction” which “culminated in the age of the Guptas.” The fact that the famous Buddhist stupas and monasteries at Bharhut and Sanchi were built and thrived under the very nose of Pushyamitra is never mentioned. Nor is the fact that the Gupta kings and queens built and endowed many Buddhist monasteries at Bodh Gaya, Nalanda and Sarnath among many other places. (…) This placing of Hindu kings on par with Muslim invaders in the context of iconoclasm suffers from serious shortcomings. Firstly, it lacks all sense of proportion when it tries to explain away the destruction of hundreds of thousands of Brahmanical, Buddhist and Jain temples by Islamic invaders in terms of the doubtful destruction of a few Buddhist and Jain shrines by Hindu kings. Secondly, it has yet to produce evidence that Hindus ever had a theology of iconoclasm which made this practice a permanent part of Hinduism. Isolated acts by a few fanatics whom no Hindu historian or pandit has ever admired, cannot explain away a full-fledged theology which inspired Islamic iconoclasm….”

“What theory can we use to get us out of the impending slump quickly and reliably? To use the 'new classical' theory of fluctuations begun at Chicago in the 1970s – the theory in which the "risk management" models are embedded – is unthinkable, since it is precisely the theory falsified by the asset price collapse. The thoughts of some have turned to John Maynard Keynes. His insights into uncertainty and speculation were deep. Yet his employment theory was problematic and the 'Keynesian' policy solutions are questionable at best…. At the end of his life Keynes wrote of 'modernist stuff, gone wrong and turned sour and silly'. He told his friend Friedrich Hayek he intended to re-examine his theory in his next book. He would have moved on. The admiration we all have for Keynes's fabulous contributions should not sway us from moving on.”

“It is not possible, I think, to rise from the perusal of the arguments of Clark and Spinoza without a deep conviction of the futility of all endeavors to establish, entirely à priori, the existence of an Infinite Being, His attributes, and His relation to the universe. The fundamental principle of all such speculations, viz. that whatever we can clearly conceive, must exist, fails to accomplish its end, even when its truth is admitted. For how shall the finite comprehend the infinite? Yet must the possibility of such conception be granted, and in something more than the sense of a mere withdrawal of the limits of phænomal existence, before any solid ground can be established for the knowledge, à priori, of things infinite and eternal.”

“In science, conjecture drives both experiment and theory for it is only by forming conjectures (hypotheses) that we can make the direction of our experiments and theories informed. If such and such is true, then I should be able to do this experiment and look for this particular result or I should be able to find this theoretical formulation. Conversely, experiment and theory drive conjecture.

“The inference to be drawn from all this is, that the made-up and dogmatic Christianity of the Constantinian period is simply an offspring of the numerous conflicting sects, half-castes themselves, born of Pagan parents. Each of these could claim representatives converted to the so-called orthodox body of Christians. And, as every newly-born dogma had to be carried out by the majority of votes, every sect colored the main substance with its own hue, till the moment when the emperor enforced this revealed olla-podrida, of which he evidently did not himself understand a word, upon an unwilling world as the religion of Christ. Wearied in the vain attempt to sound this fathomless bog of international speculations, unable to appreciate a religion based on the pure spirituality of an ideal conception, Christendom gave itself up to the adoration of brutal force as represented by a Church backed up by Constantine. Since then, among the thousand rites, dogmas, and ceremonies copied from Paganism, the Church can claim but one invention as thoroughly original with her — namely, the doctrine of eternal damnation, and one custom, that of the anathema.”

“An intellectual … lives for ideas—which means that he has a sense of dedication to the life of the mind which is very much like a religious commitment. This is not surprising, for in a very important way the role of the intellectual is inherited from the office of the cleric: it implies a special sense of the ultimate value in existence of the act of comprehension. Socrates, when he said that the unexamined life is not worth living, struck the essence of it. We can hear the voices of various intellectuals in history repeating their awareness of this feeling, in accents suitable to time, place and culture. “The proper function of the human race, taken in the aggregate,” wrote Dante in De Monarchia, “is to actualize continually the entire capacity possible to the intellect, primarily in speculation, then through its extension and for its sake, secondarily in action.””

“I began studying philosophy and economics about the same time. The similarity of the two disciplines struck me at once. I found no difficulty in grasping the differences between the great philosophical systems as they were presented by our textbooks and our teachers. Economic theory was easier still. Indeed, I thought the successive systems of economics were rather crude affairs compared with the subtleties of the metaphysicians. Having run the gamut from Plato to T. H. Green (as undergraduates do) I felt the gamut from Quesnay to Marshall was a minor theme. The technical part of the theory was easy. Give me premises and I could spin speculations by the yard. Also I knew that my 'deductions' were futile…
Meanwhile I was finding something really interesting in philosophy and in economics. John Dewey was giving courses under all sorts of titles and every one of them dealt with the same problem — how we think… And, if one wanted to try his own hand at constructive theorizing, Dewey's notion pointed the way. It is a misconception to suppose that consumers guide their course by ratiocination—they don't think except under stress. There is no way of deducing from certain principles what they will do, just because their behavior is not itself rational. One has to find out what they do. That is a matter of observation, which the economic theorists had taken all too lightly. Economic theory became a fascinating subject—the orthodox types particularly — when one began to take the mental operations of the theorists as the problem…
Of course Veblen fitted perfectly into this set of notions. What drew me to him was his artistic side… There was a man who really could play with ideas! If one wanted to indulge in the game of spinning theories who could match his skill and humor? But if anything were needed to convince me that the standard procedure of orthodox economics could meet no scientific tests, it was that Veblen got nothing more certain by his dazzling performances with another set of premises…
William Hill set me a course paper on 'Wool Growing and the Tariff.”

Wesley Clair Mitchell (1874–1948) American statistician

I read a lot of the tariff speeches and got a new sidelight on the uses to which economic theory is adapted, and the ease with which it is brushed aside on occasion. Also I wanted to find out what really had happened to wool growers as a result of protection. The obvious thing to do was to collect and analyze the statistical data... That was my first 'investigation'.

“The question "cui bono" to what practical end and advantage do your researches tend? is one which the speculative philosopher who loves knowledge for its own sake, and enjoys, as a rational being should enjoy, the mere contemplation of harmonious and mutually dependent truths, can seldom hear without a sense of humiliation. He feels that there is a lofty and disinterested pleasure in his speculations which ought to exempt them from such questioning; communicating as they do to his own mind the purest happiness (after the exercise of the benevolent and moral feelings) of which human nature is susceptible, and tending to the injury of no one, he might surely allege this as a sufficient and direct reply to those who, having themselves little capacity, and less relish for intellectual pursuits, are constantly repeating upon him this enquiry.”

“The giraffe's neck supposedly supplies a crucial example for preferring natural selection over Lamarckism as a cause of evolution. But Darwin himself (however wrongly by later judgement) did not deny the Lamarckian principle of inheritance for characters acquired by use or lost by disuse. He regarded the Lamarckian mechanism as weak, infrequent, and entirely subsidiary to natural selection, but he accepted the validity of evolution by use and disuse. Darwin does speculate about the adaptive advantage of giraffe's necks, but he cites both natural selection and Lamarckism as probable causes of elongation.”

Nothing sedates rationality like large doses of effortless money. After a heady experience of that kind, normally sensible people drift into behavior akin to that of Cinderella at the ball. They know that overstaying the festivities—that is, continuing to speculate in companies that have gigantic valuations relative to the cash they are likely to generate in the future—will eventually bring on pumpkins and mice.

“Since the belief in transmission of acquired adaptations arose from preconception rather than from evidence, it is worth observing that, rightly considered, the probability should surely be the other way. For the adaptations relate to every variety of exigency. To supply themselves with food, to find it, to seize and digest it, to protect themselves from predatory enemies whether by offence or defence, to counter-balance the changes of temperature, or pressure, to provide for mechanical strains, to obtain immunity from poison and from invading organisms, to bring the sexual elements into contact, to ensure the distribution of the type; all these and many more are accomplished by organisms in a thousand most diverse and alternative methods. Those are the things that are hard to imagine as produced by any concatenation of natural events; but the suggestions that organisms had had from the beginning innate in them a power of modifying themselves, their organs and their instincts so as to meet these multifarious requirements does not materially differ from the more overt appeals to supernatural intervention. The conception, originally introduced by Hering and independently by S. Butler, that adaptation is a consequence or product of accumulated memory was of late revived by Semon and has been received with some approval, especially by F. Darwin. I see nothing fantastic in the notion that memory may be unconsciously preserved with the same continuity that the protoplasmic basis of life possesses. That idea, though purely speculative and, as yet, incapable of proof or disproof contains nothing which our experience of matter or of life at all refutes. On the contrary, we probably do well to retain the suggestion as a clue that may some day be of service. But if adaptation is to be the product of these accumulated experiences, they must in some way be translated into terms of physiological and structural change, a process frankly inconceivable.”

The rule of law is now celebrating its final triumph as the basis of the democratic system. What is democracy other than a set of rules (the so-called rules of the game) for the solution of conflicts without bloodshed? And what constitutes good democratic government if not rigorous respect for these rules? I for one have no doubts about how such questions are to be answered. And precisely because I have no doubts I can conclude in all good conscience that democracy is the rule of law par excellence.

“Sociobiology is not just any statement that biology, genetics, and evolutionary theory have something to do with human behavior. Sociobiology is a specific theory about the nature of genetic and evolutionary input into human behavior. It rests upon the view that natural selection is a virtually omnipotent architect, constructing organisms part by part as best solutions to problems of life in local environments. It fragments organisms into “traits,” explains their existence as a set of best solutions, and argues that each trait is a product of natural selection operating “for” the form or behavior in question. Applied to humans, it must view specific behaviors (not just general potentials) as adaptations built by natural selection and rooted in genetic determinants, for natural selection is a theory of genetic change. Thus, we are presented with unproved and unprovable speculations about the adaptive and genetic basis of specific human behaviors: why some (or all) people are aggressive, xenophobic, religious, acquisitive, or homosexual.”

“There is a correlation between crude yuppies buying Porsches in the City and the number of people sleeping on the street. The tax rip-offs that are used to buy second homes, swimming pools and extended holidays mean an increase in the number of people sleeping on the street because there is insufficient public expenditure to provide housing for them. The Tories have always supported the creed which blames poverty on the poor. We believe that the poor are the victims of the society created by the Conservatives and the Government whom they so avidly support…There would indeed be no need for anyone to be homeless if a large number of previously privately rented houses were not deliberately kept empty by property speculators as a result of Government policies. It is sheer hypocrisy for Tory Members to blame the poor unfortunate people who have to sleep in cardboard boxes when they themselves put those people on the street, splash them every night as they drive past in their Porsches and kick dirt in the faces of the poor. They are the people to blame for the situation faced by so many people in London, and it is a matter of grave concern.”

“The inductive-reasoning system I have described above consists of a multitude of “elements” in the form of belief-models or hypotheses that adapt to the aggregate environment they jointly create. Thus it qualifies as an adaptive complex system. After some initial learning time, the hypotheses or mental models in use are mutually co-adapted. Thus we can think of a consistent set of mental models as a set of hypotheses that work well with each other under some criterion—that have a high degree of mutual adaptedness. Sometimes there is a unique such set, it corresponds to a standard rational expectations equilibrium, and beliefs gravitate into it. More often there is a high, possibly very high, multiplicity of such sets. In this case we might expect inductive reasoning systems in the economy—whether in stock-market speculating, in negotiating, in poker games, in oligopoly pricing, in positioning products in the market—to cycle through or temporarily lock into psychological patterns that may be non-recurrent, path-dependent, and increasingly complicated. The possibilities are rich.”

“The worker is by nature less imaginative, more level-headed than the capitalist. This is what prevents his becoming one. He is content with small gains. Trade Union officials think about the petty cash; the employer speculates in millions. You can see the difference in their representative institutions. There is no scheme too wild, no rumour too absurd, to be without repercussions on the Stock Exchange. The public house is the home of common sense.”

“Parson Amen's speculations on this interesting subject, although this may happen to be the first occasion on which he has ever heard the practice of taking scalps justified by Scripture. Viewed in a proper spirit, they ought merely to convey a lesson of humility, by rendering apparent the wisdom, nay the necessity, of men's keeping them-selves within the limits of the sphere of knowledge they were designed to fill, and convey, when rightly considered, as much of a lesson to the Puseyite, with abstractions that are quite as unintelligible to himself as they are to others; to the high-wrought and dogmatical Calvinist, who in the midst of his fiery zeal, forgets that love is the very essence of the relation between God and man; to the Quaker, who seems to think the cut of a coat essential to salvation; to the descendant of the Puritan, who whether he be Socinian, Calvinist, Universalist, or any other "1st," appears to believe that the "rock" on which Christ declared he would found his church was the "Rock of Plymouth"; and to the unbeliever, who, in deriding all creeds, does not know where to turn to find one to substitute in their stead. Humility, in matters of this sort, is the great lesson that all should teach and learn; for it opens the way to charity, and eventually to faith, and through both of these to hope; finally, through all of these, to heaven.”

“I knew Robert Burns, and I knew my father. Yet were you to ask me which had the greater natural faculty, I might perhaps actually pause before replying. Burns had an infinitely wider education, my father a far wholesomer. Besides, the one was a man of musical utterance; the other wholly a man of action, with speech subservient thereto. Never, of all the men I have seen, has one come personally in my way in whom the endowment from nature and the arena from fortune were so utterly out of all proportion. I have said this often, and partly know it. As a man of speculation — had culture ever unfolded him — he must have gone wild and desperate as Burns; hut he was a man of conduct, and work keeps all right. What strange shapable creatures we are!”

“At the present we have no adequate scientific method for representing the psychological life span. In accord with the general methods of psychology, the study of environmental influences began with classification and statistics… they gave us excellent descriptions of the home environment. The method of representation is partly akin to that of the novelist i. e., one trying to make as lifelike picture of the situation as possible by choosing expressive words and bringing out significant traits with examples. In general, the descriptions that have been made valuable to science have not been those made by scientific methods. Where theoretical concepts have been introduced with the concrete description, they often stand out as something alien. In stead of scientific descriptions they are nothing more than speculative interpretation.”

“Such people as can be prevailed upon to believe, that their reason is depraved, may easily be led by the nose, and duped into superstition at the pleasure of those in whom they confide, and there remain from generation to generation: for when they throw by the law of reason the only one which God gave them to direct them in their speculations and duty, they are exposed to ignorant or insidious teachers, and also to their own irregular passions, and to the folly and enthusiasm of those about them, which nothing but reason can prevent or restrain…”

“The most reliable and best armed groups of the mass of revolutionary contingents organised to take extreme measures to overcome the famine shall be detailed for dispatch to all stations and all uyezds of the principal grain supplying gubernias. These groups, with the participation of railwaymen delegated by local railway committees, shall be authorised, firstly, to control the movement of grain freights; secondly, take charge of the collection and storage of grain; thirdly, adopt the most extreme revolutionary measures to fight speculators and to requisition grain stocks. When making any record of requisition, arrest or execution, the revolutionary contingents shall summon at least six witnesses to be selected from the poorest section of the population closest at hand.”

“The judiciary of the United States is the subtle corps of sappers and miners constantly working under ground to undermine the foundations of our confederated fabric. They are construing our constitution from a co-ordination of a general and special government to a general and supreme one alone. This will lay all things at their feet, and they are too well versed in English law to forget the maxim, boni judicis est ampliare juris-dictionem. We shall see if they are bold enough to take the daring stride their five lawyers have lately taken. If they do, then, with the editor of our book, in his address to the public, I will say, that "against this every man should raise his voice," and more, should uplift his arm. Who wrote this admirable address? Sound, luminous, strong, not a word too much, nor one which can be changed but for the worse. That pen should go on, lay bare these wounds of our constitution, expose the decisions seriatim, and arouse, as it is able, the attention of the nation to these bold speculators on its patience. Having found, from experience, that impeachment is an impracticable thing, a mere scare-crow, they consider themselves secure for life; they sculk from responsibility to public opinion, the only remaining hold on them, under a practice first introduced into England by Lord Mansfield. An opinion is huddled up in conclave, perhaps by a majority of one, delivered as if unanimous, and with the silent acquiescence of lazy or timid associates, by a crafty chief judge, who sophisticates the law to his mind, by the turn of his own reasoning”

“We declare pragmatism to be bad, not indeed in its moral consequences (which, as a matter of fact, ought not to count in philosophy), but because it introduces into our fashion of thinking a degrading sophistry. Pragmatism, in its modern systematized form, would scarcely have been possible in earlier times. It has, however, become so since erudite scholars and original thinkers have deemed it fit to cater to a public incapable of taking a genuine interest in their researches and their speculations, a public which in the last resort wishes simply to amuse itself with these as it amuses itself with everything else, — the public of our modern democracies. We feel flattered by the plaudits of the crowd, and to procure these we are satisfied to get down to the level of those whom as thinkers we should disdain. Popular science, popular art, popular theology — only one thing was lacking — popular philosophy.”

“Recently, the press has been filled with reports of sightings of flying saucers. While we need not give credence to these stories, they allow our imagination to speculate on how visitors from outer space would judge us. I am afraid they would be stupefied at our conduct. They would observe that for death planning we spend billions to create engines and strategies for war. They would also observe that we spend millions to prevent death by disease and other causes. Finally they would observe that we spend paltry sums for population planning, even though its spontaneous growth is an urgent threat to life on our planet. Our visitors from outer space could be forgiven if they reported home that our planet is inhabited by a race of insane men whose future is bleak and uncertain.”
