“The H-bomb is coming out of my intuitive and inspirationic command, for my spirit speaketh and speaketh psychologically, intuitively, and inspirationally and guides the destinies of the nations of the earth... My Assumption is the opposite of the atomic bomb. Instead of disintegration of matter, we have the integration, the reconstitution of the real and glorious body of the Virgin in the heavens.”

Salvador Dalí (1904–1989) Spanish artist

Quote from a review of Dali's exhibition at the Carstairs Gallery; 'The New Yorker', 20 December, 1952 p. 24
Dali is referring to one of his exhibited paintings there, very probably 'The Madonna of Port Lligat'

“If an event really happened which was not a part of the uniformity of nature, it would have two properties: no evidence could give the right to believe it to any except those whose actual experience it was; and no inference worthy of belief could be founded upon it at all.
Are we then bound to believe that nature is absolutely and universally uniform? Certainly not; we have no right to believe anything of this kind. The rule only tells us that in forming beliefs which go beyond our experience, we may make the assumption that nature is practically uniform so far as we are concerned. Within the range of human action and verification, we may form, by help of this assumption, actual beliefs; beyond it, only those hypotheses which serve for the more accurate asking of questions.”

“(Performance) art is, perhaps, the first art phenomenon to clearly demonstrate that modern art has become antiquated. Modern art is based upon a single assumption. That the artwork is only what it is. It is not a picture or a metaphor for something else. It is, say, a photograph, first and only. Or, perhaps, it is a painting, first and only. This assumption still looms above us all. We automatically accept it. We fall back upon it whenever we have a problem in criticizing, accepting, or understanding a work of art.”

“The central thing I learned was that reformism was a rational strategy for workers. It was in the interest of workers to support capitalist democracy. An electoral victory of pure workers’ parties was not historically feasible, because the assumption that manual workers in industry and transportation would one day become the overwhelming majority of the population in industrializing countries was mistaken.”

“Yet the fact remains that there is a dream reality with a "structure," "landscape" and images that appear to be made of matter -- but matter that obeys different rules than those with which we are familiar. Dreams are not just psychological events. There is a dimension of reality (an "objective" dimension, if you prefer), in which all dream events happen. There are rules: Seth calls them root-assumptions that operate in all realities, our own included. We have to learn what root-assumptions govern dream reality.”

“There is a certain way of searching for the truth in mathematics that Plato is said first to have discovered; Theon named it analysis, and defined it as the assumption of that which is sought as if it were admitted and working through its consequences to what is admitted to be true. This is opposed to synthesis, which is the assuming what is admitted and working through its consequences to arrive at and to understand that which is sought.”

“The beautiful is and remains beautiful though it arouse no emotion whatever, and though there be no one to look at it. In other words, although the beautiful exists for the gratification of an observer, it is independent of him. In this sense music, too, has no aim (object), and the mere fact that this particular art is so closely bound up with our feelings by no means justifies the assumption that its aesthetic principles depend on this union.”

“In recent years there has been increased interest in the effects of internal communication on decision processes. A number of hypotheses relating the bias in information to the final decision have been proposed. In this paper we discuss two laboratory experiments which were designed to test two such hypotheses. The first experiment tests the hypothesis that cost and sales estimations are made with the implicit assumption that a biased pay-off structure exists. The second experiment tests explicitly the effects of biased and unbiased pay-off structures on estimation within an organization. An analysis of the data for the two experiments is made and some implications for further research are drawn from the results.”

“Philosophy establishes itself as a discourse by opposition to the authority of received opinion, especially the opinions sedimented as cult and as law. Philosophy puts into question the authority of what has been handed down. It is not just that there is a critique of philosophic authorities; rather, philosophy appears to be characterized by rejection of intellectual authority as such. How is philosophy to distinguish, then, a permissible authority from those many impermissible authorities which it must reject if it is to survive?
Perhaps it would be better to avoid the quandary altogether by dismissing authority in order to consider only the "content" of the claims under consideration, regardless of their pretensions. The dismissal fails for at least two reasons. The first is that there are no claims in philosophic texts that are wholly free at least from the implicit constructions of authority. If criticism takes only the content, then it ends up with something other than the texts that have constituted the discourse of philosophy. There is no Platonic "theory of Forms" dissociable from the Platonic pedagogy, that is, from the teaching authority of the Platonic Socrates. The second reason for not being able to dismiss authority altogether is that the very criticism that wants to look only at contents will impose itself as an authority in its choice of procedure. One will still have authority, but an authority that refuses to raise any question about authority.
Perhaps the question about legitimate authority could be avoided, again, by replying that the obvious criterion for claims in philosophy is the truth. The assumption here is that access to the truth is had entirely apart from the authority of philosophical traditions. Yet it is a biographical fact that one is brought into philosophy by education. First principles are learned most often not by simple observation or by the natural light of reason, but under the tutelage of some authoritative tradition.”

“Diophantus shows great Adroitness in selecting the unkown, especially with a view to avoiding an adfected quadratic…. The most common and characteristic of Diophantus' methods is his use of tentative assumptions which is applied in nearly every problem of the later books. It consists in assigning to the unknown a preliminary value which satisfies one or two only of the necessary conditions, in order that, from its failure to satisfy the remaining conditions, the operator may perceive what exactly is required for that purpose…. a third characteristic of Diophantus [is]… the use of the symbol for the unknown in different senses…. The use of tentative assumptions leads again to another device which may be called… the method of limits. This may best be illustrated by a particular example. If Diophantus wishes to find a square lying between 10 and 11, he multiplies these numbers by successive squares till a square lies between the products. Thus between 40 and 44, 90 and 99 no square lies, but between 160 and 176 there lies the square 169. Hence x^2 = \tfrac{169}{16} will lie between the proposed limits.”

“Companies are in the midst of a revolutionary transformation. Industrial age competition is shifting to information age competition. During the industrial age, from 1850 to about 1975, companies succeeded by how well they could capture the benefits from economies of scale and scope. Technology mattered, but, ultimately, success accrued to companies that could embed the new technology into physical assets that offered efficient, mass production of standard products.
During the industrial age, financial control systems were developed in companies, such as General Motors, DuPont, Matsushita, and General Electric, to facilitate and monitor efficient allocations of financial and physical capital. A summary financial measure such as return-on-capital employed (ROCE) could both direct a company’s internal capital to its most productive use and monitor the efficiency by which operating divisions used financial and physical capital to create value for shareholders.
The emergence of the information era, however, in the last decades of the twentieth century, made obsolete many of the fundamental assumptions of industrial age competition. No longer could companies gain sustainable competitive advantage by merely deploying new technology into physical assets rapidly, and by excellent management of financial assets and liabilities.”

“The theory of games was first formalised by Von Neumann & Morgenstern (1953) in reference to human economic behaviour. Since that time, the theory has undergone extensive development… Sensibly enough, a central assumption of classical game theory is that the players will behave rationally, and according to some criterion of self-interest. Such an assumption would clearly be out of place in an evolutionary context. Instead, the criterion of rationality is replaced by that of population dynamics and stability, and the criterion of self-interest by Darwinian fitness.”

“I just want to explain what I mean when I say that we should try to hold on to physical reality.
We are … all aware of the situation regarding what will turn out to be the basic foundational concepts in physics: the point-mass or the particle is surely not among them; the field, in the Faraday-Maxwell sense, might be, but not with certainty. But that which we conceive as existing ("real") should somehow be localized in time and space. That is, the real in one part of space, A, should (in theory) somehow "exist" independently of that which is thought of as real in another part of space, B. If a physical system stretches over A and B, then what is present in B should somehow have an existence independent of what is present in A. What is actually present in B should thus not depend the type of measurement carried out in the part of space A; it should also be independent of whether or not a measurement is made in A.
If one adheres to this program, then one can hardly view the quantum-theoretical description as a complete representation of the physically real. If one attempts, nevertheless, so to view it, then one must assume that the physically real in B undergoes a sudden change because of a measurement in A. My physical instincts bristle at that suggestion.
However, if one renounces the assumption that what is present in different parts of space has an independent, real existence, then I don't see at all what physics is supposed to be describing. For what is thought to be a "system" is after all, just conventional, and I do not see how one is supposed to divide up the world objectively so that one can make statements about parts.”

“As far as Hamilton, the banks and internal improvements, contrary to Professor DiLorenzo, I think, and several other people have thought, that Hamilton was the greatest Secretary of the Treasury we ever had. The assumption of the debts of the states, and the funding of the debt through the bank produced an enormous prosperity in the country, and this was all done under Washington’s administration. And if you want to speak of Federalists and people supporting the Federalist economic agenda, the first one of them was George Washington.”

“Assumptions are dangerous things to make, and like all dangerous things to make--bombs for instance, or strawberry shortcake--if you make even the tiniest mistake you can find yourself in terrible trouble. Making assumptions simply means believing things are a certain way with little or no evidence that shows you are correct, and you can see how this can lead to terrible trouble. For instance, one morning you might wake up and make the assumption that your bed was in the same place that it always was, even though you would have no real evidence that this was so. But when you got out of your bed, you might discover that it has floated out to sea, and now you would be in terrible trouble all because of the incorrect assumption that you'd made. You can see that it is better not to make too many assumptions, particularly in the morning.”

“I also don't think it's unsophisticated to think of God the Father as the spirit that arises from the crowd that exists into the future. You make sacrifices in the present so that the future is happy with you. The question is, then, what is that future that would be happy with you? It's the spirit of humanity. That's who you're negotiating with, because you make the assumption that if you forgo impulsive pleasure and get your medical degree, that when you're done in ten years and when you're a physician, humanity as such will honor your sacrifice and commitment, and it will open the doors to you. So you're treating the future as if it's a single being, and you're also treating it as if it's a compassionate judge. You're acting that out. And maybe, once we figured out that there is a future, we needed to imagine God in that form in order to concretize something that we could bargain with so that we could figure out how to use sacrifice so that we could guide ourselves into the future. Because if sacrifice is a contract with the future, but not with any particular person, then it is a contract with the spirit of humanity as such. It's something like that. To come up with the idea that you can bargain with the future is THE major idea of humankind. We suffer. What do we do about it? We figure out how to bargain with the future. And we minimize suffering in that manner.”

“The concepts of purposive behavior and teleology have long been associated with a mysterious, self-perfecting or goal-seeking capacity or final cause, usually of superhuman or super-natural origin. To move forward to the study of events, scientific thinking had to reject these beliefs in purpose and these concepts of teleological operations for a strictly mechanistic and deterministic view of nature. This mechanistic conception became firmly established with the demonstration that the universe was based on the operation of anonymous particles moving at random, in a disorderly fashion, giving rise, by their multiplicity, to order and regularity of a statistical nature, as in classical physics and gas laws. The unchallenged success of these concepts and methods in physics and astronomy, and later in chemistry, gave biology and physiology their major orientation. This approach to problems of organisms was reinforced by the analytical preoccupation of the Western European culture and languages. The basic assumptions of our traditions and the persistent implications of the language we use almost compel us to approach everything we study as composed of separate, discrete parts or factors which we must try to isolate and identify as potential causes. Hence, we derive our preoccupation with the study of the relation of two variables. We are witnessing today a search for new approaches, for new and more comprehensive concepts and for methods capable of dealing with the large wholes of organisms and personalities.”

“I do not mean to suggest that all those who call themselves monetarists make this unconscious assumption that an inflation involves this uniform rise of prices. But we may distinguish two schools of monetarism. The first would prescribe a monthly or annual increase in the stock of money just sufficient, in their judgment, to keep prices stable. The second school (which the first might dismiss as mere inflationists) wants a continuous increase in the stock of money sufficient to raise prices steadily by a "small" amount—2 or 3 per cent a year. These are the advocates of a "creeping" inflation. … I made a distinction earlier between the monetarists strictly so called and the "creeping inflationists." This distinction applies to the intent of their recommended policies rather than to the result. The intent of the monetarists is not to keep raising the price "level" but simply to keep it from falling, i. e., simply to keep it "stable." But it is impossible to know in advance precisely what uniform rate of money-supply increase would in fact do this. The monetarists are right in assuming that in a prospering economy, if the stock of money were not increased, there would probably be a mild long-run tendency for prices to decline. But they are wrong in assuming that this would necessarily threaten employment or production. For in a free and flexible economy prices would be falling because productivity was increasing, that is, because costs of production were falling. There would be no necessary reduction in real profit margins. The American economy has often been prosperous in the past over periods when prices were declining. Though money wage-rates may not increase in such periods, their purchasing power does increase. So there is no need to keep increasing the stock of money to prevent prices from declining. A fixed arbitrary annual increase in the money stock "to keep prices stable" could easily lead to a "creeping inflation" of prices.”

“One widely articulated paradigm was based on the assumption that the end of the Cold War meant the end of significant conflict in global politics and the emergence of one relatively harmonious world.

"We may be witnessing, Fukuyama argued, "… the end of history as such: that is, the end point of mankind's ideological evolution and the universalization of Western liberal democracy as the final form of human government." … The future will be devoted not to great exhilarating struggles over ideas but rather to resolving mundane economic and technical problems.

“12 principles for a 21st century conservatism.
1. The fundamental assumptions of Western civilization are valid.
2. Peaceful social being is preferable to isolation and to war. In consequence, it justly and rightly demands some sacrifice of individual impulse and idiosyncrasy.
3. Hierarchies of competence are desirable and should be promoted.
4. Borders are reasonable. Likewise, limits on immigration are reasonable. Furthermore, it should not be assumed that citizens of societies that have not evolved functional individual-rights predicated polities will hold values in keeping with such polities.
5. People should be paid so that they are able and willing to perform socially useful and desirable duties.
6. Citizens have the inalienable right to benefit from the result of their own honest labor.
7. It is more noble to teach young people about responsibilities than about rights.
8. It is better to do what everyone has always done, unless you have some extraordinarily valid reason to do otherwise.
9. Radical change should be viewed with suspicion, particularly in a time of radical change.
10. The government, local and distant, should leave people to their own devices as much as possible.
11. Intact heterosexual two-parent families constitute the necessary bedrock for a stable polity.
12. We should judge our political system in comparison to other actual political systems and not to hypothetical utopias.”

“It is with considerable reluctance that I criticize the monetarists, because, though I consider their proposed monetary policy unfeasible, they are after all much more nearly right in their assumptions and prescriptions than the majority of present academic economists. The simplistic form of the quantity theory of money that they hold is not tenable; but they are overwhelmingly right in insisting on how much "money matters," and they are right in insisting that in most circumstances, and over the long run, it is the quantity of money that is most influential in determining the purchasing power of the monetary unit. Other things being equal, the more dollars that are issued, the smaller becomes the value of each individual dollar. So at the moment the monetarists are more effective opponents of further inflation than the great bulk of politicians and even putative economists who still fail to recognize this basic truth.”

“Lenin’ s article of 1905, "Party Organization and Party Literature", was used for decades, and is still used, to justify ideologically the enslavement of the written word in Russia. It has been argued that it refers only to political literature, but this is not so: it relates to every kind of writing. It contains the words: "Down with non-partisan writers! Down with literary supermen! Literature must become part of the common cause of the proletariat, ‘ a cog and a screw’ of one single great Social Democratic mechanism set in motion by the entire politically conscious vanguard of the entire working class" (Works, vol. 10, p. 45). For the benefit of "hysterical intellectuals" who deplore this seemingly bureaucratic attitude, Lenin explains that there can be no mechanical levelling in the field of literature; there must be room for personal initiative, imagination, etc.; none the less, literary work must be part of the party’ s work and controlled by the party. This, of course, was written during the fight for "hourgeois democracy", on the assumption that Russia would in due course enjoy freedom of speech but that literary members of the party would have to display party-mindedness in their writings; as in other cases, the obligation would become general when the party controlled the apparatus of state coercion.”

“The start of work means the end to freedom, but also to doubt, intensity and wayward desires. The accountant’s ten thousand possibilities have been reduced to an agreeable handful. She has a business card which she hands over in meetings and which tells other people—and, more meaningfully perhaps, reminds her—that she is a Business Unit Senior manager, rather than a vaporous transient consciousness in an incidental universe. How satisfying it is to be held in check by the assumptions of colleagues, instead of being forced to contemplate, in the loneliness of the early hours, all that one might have been and now never will be. … Life is no longer mysterious, sad, haunting, touching, confusing or melancholy; it is a practical stage for clear-eyed action.”

However, we don’t have the privilege of a God’s eye view of that interconnectedness, so there are inevitable limits to understanding, and it is those limits that we call boundaries.

“Conversation Theory is a summarization of our assumptions and rationale from this early period. Conversations are behaviors, but special kinds of behaviors with hard-valued observables in the form of concept sharings, detected as "understandings."

“I earnestly invoke the attention of Congress to the consideration of such measures within its well-defined constitutional powers as will secure to all our people a free exercise of the right of suffrage and every other civil right under the Constitution and laws of the United States. No evil, however deplorable, can justify the assumption either on the part of the Executive or of Congress of powers not granted, but both will be highly blamable if all the powers granted are not wisely but firmly used to correct these evils. The power to take the whole direction and control of the election of members of the House of Representatives is clearly given to the General Government. A partial and qualified supervision of these elections is now provided for by law, and in my opinion this law may be so strengthened and extended as to secure on the whole better results than can be attained by a law taking all the processes of such election into Federal control. The colored man should be protected in all of his relations to the Federal Government, whether as litigant, juror, or witness in our courts, as an elector for members of Congress, or as a peaceful traveler upon our interstate railways.”

“… the principle of the limiting character of the velocity of light. This statement… is not an arbitrary assumption but a physical law based on experience. In making this statement, physics does not commit the fallacy of regarding absence of knowledge as evidence for knowledge to the contrary. It is not absence of knowledge of faster signals, but positive experience which has taught us that the velocity of light cannot be exceeded. For all physical processes the velocity of light has the property of an infinite velocity. In order to accelerate a body to the velocity of light, an infinite amount of energy would be required, and it is therefore physically impossible for any object to obtain this speed. This result was confirmed by measurements performed on electrons. The kinetic energy of a mass point grows more rapidly than the square of its velocity, and would become infinite for the speed of light.”

“Measure-relations can only be studied in abstract notions of quantity, and their dependence on one another can only be represented by formulæ. On certain assumptions, however, they are decomposable into relations which, taken separately, are capable of geometric representation; and thus it becomes possible to express geometrically the calculated results. In this way, to come to solid ground, we cannot, it is true, avoid abstract considerations in our formulæ, but at least the results of calculation may subsequently be presented in a geometric form.

“Secondly, the student is trained to accept historical mis-statements on the authority of the book. If education is a pre- paration for adult life, he learns first to accept without question, and later to make his own contribution to the creation of historical fallacies, and still later to perpetuate what he has learnt. In this way, ignorant authors are leading innocent students to hysterical conclusions. The process of the writers' mind provides excellent material for a manual on logical fallacies. Thirdly, the student is told nothing about the relationship between evidence and truth. The truth is what the book ordains and the teacher repeats. No source is cited. No proof is offered. No argument is presented. The authors play a dangerous game of winks and nods and faints and gestures with evidence. The art is taught well through precept and example. The student grows into a young man eager to deal in assumptions but inapt in handling inquiries. Those who become historians produce narratives patterned on the textbooks on which they were brought up. Fourthly, the student is compelled to face a galling situation in his later years when he comes to realize that what he had learnt at school and college was not the truth. Imagine a graduate of one of our best colleges at the start of his studies in history in a university in Europe. Every lecture he attends and every book he reads drive him mad with exasperation, anger and frustration. He makes several grim discoveries.

“Nearly fifty years ago… Douglas McGregor launched a debate over how to manage The Human Side of the Enterprise. By comparing what he called Theory X and Theory Y perspectives, he challenged the management profession to reexamine its assumptions about the motivations employees bring to their jobs. The question was: Could employees be trusted and empowered to do good work, or did they have to be closely directed, monitored, and controlled to act in the interests of the firm? While McGregor’s Theory Y sparked important innovations in human resource practices, it did not challenge fundamental assumptions underpinning the 20th Century organizational model. If, as is widely recognized, human capital and knowledge are the most important sources of value for the 21st Century organization, then fundamental assumptions about the relationship between work and organizations will also need to be challenged.”

“… 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.”

That is perfectly possible, but you can only hope to succeed on that policy alone on two assumptions; I am coming to the history in a moment. Those two assumptions are, first, unanimity among the political parties at home, and, secondly, continuity of policy. It was because both these preliminary necessities were absent in the case of Ireland that the Irish question went on, as it did, for a generation, and culminated, as it did, between the alternatives of complete surrender or war.

“The paper develops a new theory for the analysis of games with incomplete information where the players are uncertain about some important parameters of the game situation, such as the payoff functions, the strategies available to various players, the information other players have about the game, etc. However, each player has a subjective probability distribution over the alternative possibilities.
In most of the paper it is assumed that these probability distributions entertained by the different players are mutually "consistent," in the sense that they can be regarded as conditional probability distributions derived from a certain "basic probability distribution" over the parameters unknown to the various players. But later the theory is extended also to cases where the different players' subjective probability distributions fail to satisfy this consistency assumption.”

The ad featured a photograph of a group of animal rights protestors under the caption: ‘Thanks to animal research, they’ll be able to protest 20.8 years longer.’ But imagine a parallel universe in which medical research is conducted on black people, and in which an equivalent foundation employs an equivalent argument: ‘Thanks to research on black people, these white protesters will be able to protest against experimentation on black people 20.8 years longer’! Would this justify experimentation on black people? Obviously not! We would immediately reject the argument as founded on a deeply racist assumption, namely, that the costs inflicted on ‘mere’ black people are justified by the benefits produced for whites.

“Although Black feminism and some currents of postmodernist theory share some common assumptions and common language, these are overshadowed by key differences that make them two distinct approaches to combatting oppression. Thus the concept of intersectionality has two different political foundations--one informed primarily by Black feminism and the other by postmodernism. More recent evolution of the post-structuralist approach to identity politics and intersectionality, which has a strong influence over today's generation of activists, places an enormous emphasis on changing individual behavior as the most effective way to combat oppression. This has given rise to the idea of individuals "calling out" interpersonal acts of perceived oppression as a crucial political act. More generally, intersectionality in postmodern terms, even among those who have no idea what postmodernism is.”

“Philosophy of religion … really amounts to … philosophizing on certain favorite assumptions that are not confirmed at all.”

“In the preface to the reissue of Risk, Uncertainty and Proﬁt, Frank Knight makes the penetrating observation that under the conditions envisaged above the velocity of circulation would become inﬁnite and so would the price level. This is perhaps an over-dramatic way of saying that nobody would hold money, and it would become a free good to go into the category of shell and other things which once served as money. We should expect too that it would not only pass out of circulation, but it would cease to be used as a conventional numeraire in terms of which prices are expressed. Interest bearing money would emerge. Of course, the above does not happen in real life, precisely because uncertainty, contingency needs, non-synchronization of revenues and outlay, transaction frictions, etc., etc., all are with us. But the abstract special case analyzed above should warn us against the facile assumption that the average levels of the structure of interest rates are determined solely or primarily by these differential factors. At times they are primary, and at other times, such as the twenties in this country, they may not be. As a generalization I should hazard the hypothesis that they are likely to be of great importance in an economy in which there is a “quasi-zero" rate of interest. I think by this hypothesis one can explain many of the anomalies of the United States money market in the thirties.”

“Pure mathematics is a collection of hypothetical, deductive theories, each consisting of a definite system of primitive, undefined, concepts or symbols and primitive, unproved, but self-consistent assumptions (commonly called axioms) together with their logically deducible consequences following by rigidly deductive processes without appeal to intuition.”

“In the days when we could take it for granted that journalism mattered, we could only share assumptions about what it was, how it was delivered and funded, but this is not the case any more.”

“It is an irony of fate (or a triumph of folly) that Hamas was created, in fact, with the help of Israel itself. Much as the Americans created the al-Qaeda of Osama bin Laden in order to fight against the Soviet army in Afghanistan, Israel supported the Islamic movement in the occupied territories as a counterweight to the PLO. The assumption was that pious Muslims would spend their time praying in the mosques and would not support the secular PLO, which was then considered the arch-enemy. But when the first intifada broke out at the end of 1987, the Islamists organized as Hamas (the Arabic initials of "Islamic Resistance Movement") and quickly became the most efficient underground fighting organization. However, the Security Service started to act against them only after a whole year of the intifada had passed.”

“We have numerous, extremely naïve assumptions built into our thinking, and our most venerable explanatory engines, such as science, happen also to be our oldest explanatory engines, and therefore they have built into them the most naïve and unexamined assumptions.”

“I'm not concerned about avoiding anything that happened three years ago or worried about letdowns or things of that nature. When you use the term 'letdown' you proceed with the assumption that this is a continuation of something that happened in the past.”

Question

“One source of misunderstanding is that many of the commentators have been economists who have looked at the Moral Sentiments simply in order to find some relevance for The Wealth of Nations. This gave rise to the so-called Adam Smith problem, a supposed inconsistency between the psychological assumptions of the two books. Another source of error has been a failure to note whether a particular passage was written for the first or for the sixth edition.”

“What mathematics, therefore are expected to do for the advanced student at the university, Arithmetic, if taught demonstratively, is capable of doing for the children even of the humblest school. It furnishes training in reasoning, and particularly in deductive reasoning. It is a discipline in closeness and continuity of thought. It reveals the nature of fallacies, and refuses to avail itself of unverified assumptions. It is the one department of school-study in which the sceptical and inquisitive spirit has the most legitimate scope; in which authority goes for nothing. In other departments of instruction you have a right to ask for the scholar’s confidence, and to expect many things to be received on your testimony with the understanding that they will be explained and verified afterwards. But here you are justified in saying to your pupil “Believe nothing which you cannot understand. Take nothing for granted.” In short, the proper office of arithmetic is to serve as elementary 268 training in logic. All through your work as teachers you will bear in mind the fundamental difference between knowing and thinking; and will feel how much more important relatively to the health of the intellectual life the habit of thinking is than the power of knowing, or even facility of achieving visible results. But here this principle has special significance. It is by Arithmetic more than by any other subject in the school course that the art of thinking—consecutively, closely, logically—can be effectually taught.”
