Quotes about logic (1454 quotes, page 6)

“Despite the roar of voices wanting to equate strategy with ambition, leadership, “vision,” planning, or the economic logic of competition, strategy is none of these. The core of strategy work is always the same: discovering the critical factors in a situation and designing a way of coordinating and focusing actions to deal with those factors.”

“Undoubtedly the stories about them [hard-boiled detectives] had a fantastic element. Such things happened, but not so rapidly, nor to so close-knit a group of people, nor within so narrow a frame of logic. This was inevitable because the demand was for constant action; if you stopped to think you were lost. When in doubt, have a man come through a door with a gun in his hand.”

“Edmund Gettier convinced most philosophers that the received wisdom of millennia about the concept of knowledge was mistaken: “knowledge” was not simply a matter of having a justified, true belief … A justified true belief isn’t “knowledge” when the justification for the true belief isn’t the cause of why the agent holds the belief. As Philip Kitcher put the point, in explaining the stimulus Gettier provided to the “naturalistic” turn in epistemology: “the epistemic status of a belief state depends on the etiology of the state.” … We can understand, now, the logic of the hermeneutics of suspicion as exploiting precisely this point about the epistemic status of belief: we should be suspicious of the epistemic status of beliefs that have the wrong causal etiology. That’s the lesson of the Gettier counter-examples, and it is the lesson which underwrites the suspicion that Marx, Nietzsche, and Freud recommend by way of providing alternative causal trajectories to explain our beliefs. To be sure, beliefs with the wrong causal etiology might be true; but since they are no longer cases of knowledge, we have no reason to presume that to be the case.”

“Element had an existence from the time he [God] had. The pure principles of element are principles which can never be destroyed; they may be organized and re-organized, but not destroyed. They had no beginning, and can have no end.... [T]he mind of man — the immortal spirit. Where did it come from? All learned men and doctors of divinity say that God created it in the beginning; but it is not so: the very idea lessens man in my estimation. I do not believe the doctrine; I know better. Hear it, all ye ends of the world; for God has told me so... We say that God himself is a self-existent being. Who told you so? It is correct enough; but how did it get into your heads? Who told you that man did not exist in like manner upon the same principles? Man does exist upon the same principles. God made a tabernacle and put a spirit into it, and it became a living soul.... The mind or the intelligence which man possesses is [co-eternal] with God himself. I know that my testimony is true... Is it logical to say that the intelligence of spirits is immortal, and yet that it had a beginning? The intelligence of spirits had no beginning, neither will it have an end. That is good logic. That which has a beginning may have an end. There never was a time when there were not spirits; for they are [co-eternal] with our Father in heaven.... I take my ring from my finger and liken it unto the mind of man—the immortal part, because it has no beginning. Suppose you cut it in two; then it has a beginning and an end; but join it again, and it continues one eternal round. So with the spirit of man. As the Lord liveth, if it had a beginning, it will have an end. All the fools and learned and wise men from the beginning of creation, who say that the spirit of man had a beginning, prove that it must have an end; and if that doctrine is true, then the doctrine of annihilation would be true. But if I am right, I might with boldness proclaim from the house-tops that God never had the power to create the spirit of man at all. God himself could not create himself.”

“Take an eighteenth century English whig. Let him be a mystic. Endow him with the logical subtlety of the great schoolmen and their belief in the powers of human reason, with the business capacity of a successful lawyer, and with the lucidity of the best type of French mathematician. Inspire him (Heaven knows how) in his early youth with a passion for Hegel. Then subject him to the teaching of Sidgwick and the continual influence of Moore and Russell. Set him to expound Hegel. What will be the result? Hegel himself could not have answered this question a priori, but the course of world history has solved it ambulando by producing McTaggart.”

“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.”

“Of the three great skeptics I interviewed, Popper was the first to make his mark. His philosophy stemmed from his effort to distinguish pseudoscience, such as Marxism or astrology or Freudian psychology, from genuine science, such as Einstein's theory of relativity. The latter, Popper decided, was testable; it made predictions about the world that could be empirically checked. The logical positivists had said as much. But Popper denied the positivist assertion that scientists can prove a theory through induction, or repeated empirical tests or observations. One never knows if one's observations have been sufficient; the next observation might contradict all that preceded it. Observations can never prove a theory but can only disprove, or falsify it. Popper often bragged that he had "killed" logical positivism with this argument.”

“America's first great surrealist artists were named Walt Disney, Max Fleischer, and Tex Avery. Their artistic medium was cartoon animation, though we must remember that cartoons of this era were seen not only by children but by a mixed audience, consisting mainly of adults. These men took — quite literally — the principles of surrealism and turned them into mass entertainment. As Fleischer's scantily clad Betty Boop ran through a phantasmagoric underground landscape to the driving beat of Cab Calloway's "Minnie the Moocher," moviegoers of the Thirties saw surrealist dream-logic unfold more powerfully than in any experimental poem created in Greenwich Village. To this day the greatest moment of North American surrealism is probably Dumbo's drunken nightmare choreographed to the demonic oom-pah-pah of "Pink Elephants on Parade" from Walt Disney's 1941 movie. When the surrealist style was so quickly assimilated into mass-media comedy, what avant-garde poet could consider it sufficiently chic?”

In our offices and schools, everywhere people are discussing politics- suspecting each other; hatching plots; promoting this person, bringing down that one, pushing the third aside; doing no constructive work while, in the country at large, killing, banditry and murder hold sway. Chaos reigns, the established order has ceased to exist… The military and the police… no longer know where their duty lies.

“Our new government is founded upon exactly the opposite ideas; its foundations are laid, its cornerstone rests, upon the great truth that the negro is not equal to the white man; that slavery, subordination to the superior race, is his natural and normal condition. This, our new government, is the first, in the history of the world, based upon this great physical, philosophical, and moral truth. This truth has been slow in the process of its development, like all other truths in the various departments of science. It has been so even amongst us. Many who hear me, perhaps, can recollect well, that this truth was not generally admitted, even within their day. The errors of the past generation still clung to many as late as twenty years ago. Those at the north, who still cling to these errors, with a zeal above knowledge, we justly denominate fanatics. All fanaticism springs from an aberration of the mind from a defect in reasoning. It is a species of insanity. One of the most striking characteristics of insanity, in many instances, is forming correct conclusions from fancied or erroneous premises; so with the anti-slavery fanatics. Their conclusions are right if their premises were. They assume that the negro is equal, and hence conclude that he is entitled to equal privileges and rights with the white man. If their premises were correct, their conclusions would be logical and just but their premise being wrong, their whole argument fails. I recollect once of having heard a gentleman from one of the northern States, of great power and ability, announce in the House of Representatives, with imposing effect, that we of the South would be compelled, ultimately, to yield upon this subject of slavery, that it was as impossible to war successfully against a principle in politics, as it was in physics or mechanics. That the principle would ultimately prevail. That we, in maintaining slavery as it exists with us, were warring against a principle, a principle founded in nature, the principle of the equality of men. The reply I made to him was, that upon his own grounds, we should, ultimately, succeed, and that he and his associates, in this crusade against our institutions, would ultimately fail. The truth announced, that it was as impossible to war successfully against a principle in politics as it was in physics and mechanics, I admitted; but told him that it was he, and those acting with him, who were warring against a principle. They were attempting to make things equal which the Creator had made unequal.”

“n a word, this new office of Imperator was nothing else than the primitive regal office re-established; for it was those very restrictions--as respected the temporal and local limitation of power, the collegiate arrangement, and the cooperation of the senate or the community that was necessary for certain cases-- which distinguished the consul from the king.(17) There is hardly a trait of the new monarchy which was not found in the old: the union of the supreme military, judicial, and administrative authority in the hands of the prince; a religious presidency over the commonwealth; the right of issuing ordinances with binding power; the reduction of the senate to a council of state; the revival of the patriciate and of the praefecture of the city. But still more striking than these analogies is the internal similarity of the monarchy of Servius Tullius and the monarchy of Caesar; if those old kings of Rome with all their plenitude of power had yet been rulers of a free community and themselves the protectors of the commons against the nobility, Caesar too had not come to destroy liberty but to fulfil it, and primarily to break the intolerable yoke of the aristocracy. Nor need it surprise us that Caesar, anything but a political antiquary, went back five hundred years to find the model for his new state; for, seeing that the highest office of the Roman commonwealth had remained at all times a kingship restricted by a number of special laws, the idea of the regal office itself had by no means become obsolete. At very various periods and from very different sides-- in the decemviral power, in the Sullan regency, and in Caesar's own dictatorship--there had been during the republic a practical recurrence to it; indeed by a certain logical necessity, whenever an exceptional power seemed requisite there emerged, in contradistinction to the usual limited -imperium-, the unlimited -imperium- which was simply nothing else than the regal power.”

“The ultimate of taxation-for-social-purposes is absolutism, not only because the growing fiscal power carries an equal increase in political power, but because the investment of revenue in the individual by the State gives it a pecuniary interest in him. If the State supplies him with all his needs and keeps him in health and a degree of comfort, it must account him a valuable asset, a piece of capital. Any claim to individual rights is liquidated by society's cash investment. The State undertakes to protect society's investment, as to reimbursement and profit, by way of taxation. The motor power lodged in the individual must be put to the best use so that the yield will further social ends, as foreseen by the management. Thus, the fiscal scheme which begins with distribution is forced by the logic of events into control of production. And the concept of natural rights is inconsistent with the social obligation of the individual. He lives for the State which nurtured him. He belongs to the State by right of purchase.”

“I have encountered a few "creationists" and because they were usually nice, intelligent people, I have been unable to decide whether they were really mad, or only pretending to be mad. If I was a religious person, I would consider creationism nothing less than blasphemy. Do its adherents imagine that God is a cosmic hoaxer who has created the whole vast fossil record for the sole purpose of misleading humankind? And, although I do not necessarily agree with the paleontologist Teilhard de Chardin's advocacy of evolution as a major proof of the glory of God, de Chardin's attitude is both logical and inspiring. A creator who laid the foundations for the entire future at the beginning of time is far more awesome than a clumsy tinkerer who constantly modifies his creations and throws away entire species in the process.”

“There are here two assumptions about 'evaluations ', which I will call assumption (1) and assumption (2). Assumption (1) is that some individual may, without logical error, base his beliefs about matters of value entirely on premises which no one else would recognise as giving any evidence at all. Assumption (2) is that, given the kind of statement which other people regard as evidence for an evaluative conclusion, he may refuse to draw the conclusion because this does not count as evidence for him.”

“But this logic has also worked to exclude the decorative — the decorative insofar as it functions solely as decoration. It's as though aesthetic value, quality, could be preserved only by concentrating on "absolute" or "autonomous" art: thus on visual art — including even architecture — that held and moved and stirred the beholder as sheer decoration could not. Decoration is asked to be "merely" pleasing, "merely" embellishing, and the "functional" logic of Modernism leaves no room, apparently, for such "mereness."”

“From the methodological standpoint, however, we see that 'mechanism' and 'vitalism' by no means form the mutually exclusive disjunction they have been supposed to do. If a 'non-mechanist' wishes to deny the assumption of methodological mechanism that biological explanations must also be physico-chemical ones, it is obviously by no means intended that the required explanation must be 'vitalistic', i. e. involving the assumption that in living organisms factors analogous to psychical ones are 'at work'. A 'non-mechanistic' theory which is not all 'vitalistic' thus appears to be logically possible, and if we make a critical study of mechanism and vitalism this possibility will be seen to be of special importance.”

“Geometry is that of mathematical science which is devoted to consideration of form and size, and may be said to be the best and surest guide to study of all sciences in which ideas of dimension or space are involved. Almost all the knowledge required by navigators, architects, surveyors, engineers, and opticians, in their respective occupations, is deduced from geometry and branches of mathematics. All works of art constructed according to the rules which geometry involves; and we find the same laws observed in the works of nature. The study of mathematics, generally, is also of great importance in cultivating habits of exact reasoning; and in this respect it forms a useful auxiliary to logic.”

“The subject of a science is never well circumscribed and there is little use sharpening its definition. However, nobody will deny that physics deals with nature and sociology with human society in some of their aspects. With logic, it is another matter. Logic is usually understood nowadays as a study of certain formal systems, though in former times there were philosophers who held that the subject matter of logic was the formal rules of human thought. In the latter sense it would be an empirical rather than a formal science, though its empirical subject matter would still be fundamentally different from that of psychology of thinking. One interpretation of logic does not exclude the other. Formal approaches are often easier than empirical ones, and for this reason one can understand why logic as a study of formal systems has till now made more progress than logic as a study of the formal rules of thought, even if restricted to scientific thought.”

“More than any of his predecessors Plato appreciated the scientific possibilities of geometry... By his teaching he laid the foundations of the science, insisting upon accurate definitions, clear assumptions, and logical proof. His opposition to the materialists, who saw in geometry only what was immediately useful to the artisan and the mechanic is… clear. …That Plato should hold the view… is not a cause for surprise. The world's thinkers have always held it. No man has ever created a mathematical theory for practical purposes alone. The applications of mathematics have generally been an afterthought.”

“At the moment there is a great tendency in painting to discover the 'new' harmony by constructive means whereby the rhythmic is built on an almost geometric form... I am certain that our own modern harmony is not to be found in the 'geometric' way, but rather in the anti-geometric, anti-logical way. And this way is that of 'dissonance in art', in painting, therefore, just as much as in music. And 'today's' dissonance in painting and music is merely the consonance of 'tomorrow.”

“Yoga teaches that whatever we want in life we can have if we are willing to provide it for others. So if yogis want to be free, they understand that to deprive others of freedom will ultimately not benefit their project—to be free themselves. Following that logic, yogis abhor slavery and examine their own lives to find ways that they themselves might be condoning slavery and then eradicate those ways of acting. The fact is that animals who are raised for food are slaves. Making kind choices when it comes to the food we eat is one of the most basic ways to begin to ensure our own happiness and freedom. The cause for our own happiness, health, and freedom lies in how happy and free we can make the lives of others. The definition of others includes other animals.”

“Confronted, when the weather is fine and I am in propitious emotional circumstances, with certain landscapes, certain works of art, certain human beings, I know, for the time being, that God's in his heaven and all's right with the world. On other occasions, skies and destiny being inclement, I am no less immediately certain of the malignant impersonality of an uncaring universe. Every human being has had similar experiences. This being so, the sensible thing to do would be to accept the facts and frame a metaphysic to fit them. But with that talent for doing the wrong thing, that genius for perversity, so characteristically human, men have preferred, especially in recent times, to take another course. They have either denied the existence of these psychological facts; or if they have admitted them, have done so only to condemn as evil all such experiences as cannot be reconciled in a logical system with whatever particular class of experiences they have chosen, arbitrarily, to regard as "true" and morally valuable. Every man tries to pretend that he is consistently one kind of person and does his best consistently to worship one kind of God. And this despite the fact that he experiences diversity and actually feels himself in contact with a variety of divinities.”

“If we except the great name of Newton (and the exception is one that the great Gauss himself would have been delighted to make) it is probable that no mathematician of any age or country has ever surpassed Gauss in the combination of an abundant fertility of invention with an absolute vigorousness in demonstration, which the ancient Greeks themselves might have envied. It may be admitted, without any disparagement to the eminence of such great mathematicians as Euler and Cauchy that they were so overwhelmed with the exuberant wealth of their own creations, and so fascinated by the interest attaching to the results at which they arrived, that they did not greatly care to expend their time in arranging their ideas in a strictly logical order, or even in establishing by irrefragable proof propositions which they instinctively felt, and could almost see to be true. With Gauss the case was otherwise. It may seem paradoxical, but it is probably nevertheless true that it is precisely the effort after a logical perfection of form which has rendered the writings of Gauss open to the charge of obscurity and unnecessary difficulty. The fact is that there is neither obscurity nor difficulty in his writings, as long as we read them in the submissive spirit in which an intelligent schoolboy is made to read his Euclid. Every assertion that is made is fully proved, and the assertions succeed one another in a perfectly just analogical order… But when we have finished the perusal, we soon begin to feel that our work is but begun, that we are still standing on the threshold of the temple, and that there is a secret which lies behind the veil and is as yet concealed from us. No vestige appears of the process by which the result itself was obtained, perhaps not even a trace of the considerations which suggested the successive steps of the demonstration. Gauss says more than once that for brevity, he gives only the synthesis, and suppresses the analysis of his propositions. Pauca sed matura—few but well matured… If, on the other hand, we turn to a memoir of Euler's, there is a sort of free and luxuriant gracefulness about the whole performance, which tells of the quiet pleasure which Euler must have taken in each step of his work; but we are conscious nevertheless that we are at an immense distance from the severe grandeur of design which is characteristic of all Gauss's greater efforts.”

“By virtue of the universal concept, thought attains mastery over the particular cases. However, the most formalized universe of logic still refers to the most general structure of the given, experienced world; the pure form is still that of the content which it formalizes. The idea of formal logic itself is a historical event in the development of the mental and physical instruments for universal control and calculability. In this undertaking man had to create theoretical harmony out of actual discord, to purge thought from contradictions, to hypostatize identifiable and fungible units in the complex process of society and nature. Under the rule of formal logic, the notion of the conflict between essence and appearance is expendable if not meaningless; the material content is neutralized; the principle of identity is separated from the principle of contradiction (contradictions are the fault of incorrect thinking); final causes are removed from the logical order. Well defined in their scope and function, concepts become instruments of prediction and control. Formal logic is thus the first step on the long road to scientific thought”

“We especially need imagination in science. It is not all mathematics, nor all logic, but it is somewhat beauty and poetry. There will come with the greater love of science greater love to one another. Living more nearly to Nature is living farther from the world and from its follies, but nearer to the world's people; it is to be of them, with them, and for them, and especially for their improvement. We cannot see how impartially Nature gives of her riches to all, without loving all, and helping all; and if we cannot learn through Nature's laws the certainty of spiritual truths, we can at least learn to promote spiritual growth while we are together, and live in a trusting hope of a greater growth in the future.”

The mental posture they habituate the youth in is the posture of conformity. They require belief, not investigation. They impose reverence for the past and idealization of the present. They envision the future as a perpetuation of the past, not as a new creation of it. They are Main Street's most powerful instrument of self-reproduction without variation…. They enable government both visible and invisible to continue by consent, for they forestall and inhibit in the citizens of the land the technique of doubt and dissent which is the necessary condition of good government and the true inward-ness of that eternal vigilance so notoriously the price of liberty."”

“The realization of the pathetic frailty of the knowledge or beliefs on which our life depends thus leads not to despair but to open-eyed courage. But it also points to a most intimate connection between scientific method and liberal civilization. Science is not, as is popularly conceived, a new set of dogmas taught by a newer and better set of priests called scientists. It is rather a method which is based on a critical attitude to all plausible and self-evident propositions. It seeks not to reject them, but to find out what evidence there is to support them rather than their possible alternatives. This open eye for possible alternatives, each to receive the same logical treatment before we can determine which is the better grounded, is the essence of liberalism in art, morals, and politics.... Like science, liberalism insists on a critical examination of the content of all our beliefs, principles, or initial hypotheses and on subjecting them to a continuous process of verification so that they will be progressively better founded in experience and reason.”

Would it take me a second, or half a second, or an eighth of a second, or would I not notice that there was anything wrong with him at all?’ And they’d say, ‘Oh, an eighth of a second, you’d know immediately.’ And I would say to them, ‘Well, if you know that I would know immediately, then you knew immediately as well.’ It’s a logical consequence, really. And they would accept that. ‘And yet, you chose to associate with him, knowing full well that he was no good; and I tell you this, because it’s very necessary you should understand your own part in the predicament you now find yourself in, because if you don’t understand it, or don’t think about it, you’re just going to repeat it.’ which is of course, a very, very common pattern.”

“Today we preach that science is not science unless it is quantitative. We substitute correlations for causal studies, and physical equations for organic reasoning. Measurements and equations are supposed to sharpen thinking, but, in my observation, they more often tend to make the thinking noncausal and fuzzy. They tend to become the object of scientific manipulation instead of auxiliary tests of crucial inferences.
Many - perhaps most - of the great issues of science are qualitative, not quantitative, even in physics and chemistry. Equations and measurements are useful when and only when they are related to proof; but proof or disproof comes first and is in fact strongest when it is absolutely convincing without any quantitative measurement.
Or to say it another way, you can catch phenomena in a logical box or in a mathematical box. The logical box is coarse but strong. The mathematical box is fine-grained but flimsy. The mathematical box is a beautiful way of wrapping up a problem, but it will not hold the phenomena unless they have been caught in a logical box to begin with.”

Yet creationists still use those same ridiculous rationalizations because they will never accept where their beliefs are in error!

More amazing still is how often they will actually lie in defense of their alleged truth. Every publication promoting creation over any avenue of actual science contains misquotes, misdefinitions, and misrepresented misinformation, while their every appeal to reason is based entirely on erroneous assumptions and logical fallacies. There is a madness to their method, but it is naught but propaganda.”

“Land, n. A part of the earth's surface, considered as property. The theory that land is property subject to private ownership and control is the foundation of modern society, and is eminently worthy of the superstructure. Carried to its logical conclusion, it means that some have the right to prevent others from living; for the right to own implies the right exclusively to occupy; and in fact laws of trespass are enacted wherever property in land is recognized. It follows that if the whole area of terra firma is owned by A, B and C, there will be no place for D, E, F and G to be born, or, born as trespassers, to exist.”

“All this (the early excitement of Cybernetics) is now history, and in the decade which elapsed since these early baby steps of interdisciplinary communication, many more threads were picked up and interwoven into a remarkable tapestry of knowledge and endeavour: Bionics. It is good omen that at the right time the right name was found. For, bionics extends a great invitation to all who are willing not to stop at the investigation of a particular function or its realization, but to go on and to seek the universal signiﬁcance of these functions in living or artiﬁcial organisms.
The reader who goes through the following papers which constitute the transactions of the ﬁrst symposium held under the name Bionics will be surprised by the multitude of astonishing and unforeseen connections between concepts he believed to be familiar with. For instance, a couple of years ago, who would have thought to relate the reliability problem to multi-valued logics; or, who would have thought that integral or differential geometry would serve as an adequate tool in the theory of abstraction? It is hard to say in all these cases who was teaching whom: The life-sciences the engineering sciences, or vice versa? And rightly so, for it guarantees optimal information ﬂow, and everybody gains…”
