Theory And Practical Quotes & Sayings

We had all opted to take City's financial reporting course work, which, in theory, meant we wanted to write about stock prices and corporate takeovers. That, of course, was a joke. No one still in their twenties, and broke, goes into journalism to write about money - a subject in which they still have zero practical experience. — Chris Ayres

But the kid could think, too. He wasn't academic like Joe, but he was practical. His IQ was probably about the same, but it was a get-the-job-done type of street smart IQ, not any kind of for-the-sake-of-it cerebral indulgence. Reacher liked facts, for sure, and information too, but not theory. He was a real-world character. Stan had no idea what the future held for the guy. No idea at all, except he was going to be too big to fit inside a tank or an airplane cockpit. So it was going to have to be something else. — Lee Child

His [Thomas Edison] method was inefficient in the extreme, for an immense ground had to be covered to get anything at all unless blind chance intervened and, at first, I was almost a sorry witness of his doings, knowing that just a little theory and calculation would have saved him 90 per cent of the labor. But he had a veritable contempt for book learning and mathematical knowledge, trusting himself entirely to his inventor's instinct and practical American sense. In view of this, the truly prodigious amount of his actual accomplishments is little short of a miracle. — Nikola Tesla

The theories and speculations of men concern us more than their puny accomplishment. It is with a certain coldness and languor that we loiter about the actual and so-called practical. — Henry David Thoreau

Terrorism has no religion is a theory, and the religion of terrorism is a real threat and practical thing. — Satyendra Singh 'Shyamal'

Itwas one time when people thought the value of the fine structure constant wasimportant. Now of course it's still important, of course, as a practical matter,but we now know that the value it has is a function, that in any fundamental theory you derive the fine structure constant as a function of all sorts of mass ratios and so on, and it's not really that fundamental. — Steven Weinberg

By the 'mud-sill' theory it is assumed that labor and education are incompatible; and any practical combination of them impossible. According to that theory, a blind horse upon a tread-mill, is a perfect illustration of what a laborer should be
all the better for being blind, that he could not tread out of place, or kick understandingly. According to that theory, the education of laborers, is not only useless, but pernicious, and dangerous. In fact, it is, in some sort, deemed a misfortune that laborers should have heads at all. — Abraham Lincoln

I do not think much of the good luck theory of self-made men. It is worth but little attention and has no practical value. — Frederick Douglass

One important idea is that science is a means whereby learning is achieved, not by mere theoretical speculation on the one hand, nor by the undirected accumulation of practical facts on the other, but rather by a motivated iteration between theory and practice. — George E.P. Box

Although it may be difficult in theory to know what is just and equal, the practical difficulty of inducing those to forbear who can, if they like, encroach, is far greater, for the weaker are always asking for equality and justice, but the stronger care for none of these things. — Aristotle.

I picked economics at the end of my undergraduate time because it seemed to be a really nice combination of theory, including mathematical theory on one hand, and things that are quite practical that you can touch and see and feel. So I picked it, and I consciously thought of it as an experiment to see if I liked it. And it worked. — Michael Spence

For the theory-practice iteration to work, the scientist must be, as it were, mentally ambidextrous; fascinated equally on the one hand by possible meanings, theories, and tentative models to be induced from data and the practical reality of the real world, and on the other with the factual implications deducible from tentative theories, models and hypotheses. — George E.P. Box

The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation. — Paul Dirac

I believe what really happens in history is this: the old man is always wrong; and the young people are always wrong about what is wrong with him. The practical form it takes is this: that, while the old man may stand by some stupid custom, the young man always attacks it with some theory that turns out to be equally stupid. — G.K. Chesterton

Everyone can err, but Stalin considered that he never erred, that he was always right. He never acknowledged to anyone that he made any mistake, large or small, despite the fact that he made not a few mistakes in the matter of theory and in his practical activity. — Nikita Khrushchev

We shall do well ever to remember, that Christianity is not a mere speculative theory, that is to inform the mind; but a great practical lesson, to renew the heart, and to bring us back to the state from whence we are fallen. — Charles Simeon

I'm not into politics but I am committed to a cause: ensuring design technology and engineering stays on the U.K. curriculum, alongside science and maths - grounding abstract theory, merging the practical with the academic. — James Dyson

Fundamental analysis often works, but it often fails. Technical analysis often works, and then it does not work. Economists speak of economic cycles, but none can be found analytically. Traders speak of market cycles; they too cannot be proven. To top it off, the critics of the EMH have been unable to offer an alternative that takes all the discrepancies into account. In few other areas are theory and practical experience in such little agreement. — Edgar E. Peters

The triumph of science has been mainly due to its practical utility, and there has been an attempt to divorce this aspect from that of theory, thus making science more and more a technique, and less and less a doctrine as to the nature of the world. The penetration of this point of view to philosophers is very recent. — Bertrand Russell

My father looked carelessly at the title page of my book, and said, "Ah! Cornelius Agrippa! My dear Victor, do not waste your time upon this; it is sad trash."
If, instead of this remark, my father had taken the pains to explain to me, that the principles of Agrippa had been entirely exploded, and that a modern system of science had been introduced, which possessed much greater powers than the ancient, because the powers of the latter were chimerical, while those of the former were real and practical; under such circumstances, I should certainly have thrown Agrippa aside, and, with my imagination warmed as it was, should probably have applied myself to the more rational theory of chemistry which has resulted from modern discoveries — Mary Shelley

The modern brand builder faces a difficult issue; communications theory is based on attitude change, and has limited implications for behaviour change. Games are characterised by interaction and behaviour rather than attitude, making the principles of gaming suited to brand building. I believe that games provide a practical template for brands that actively change behaviour. — Craig Atkinson

I make a distinction between theory and methodology, the latter being the practical deployment of a premise. Theory on the contrary may well be applied, hence becomes methodology without a hitch, but isn't necessarily practical at all. — Paul Fry

When dealing with Arab society, [we are dealing with] a production system that is in competition with others (and not with a theoretical opposition between specific economic rationalities), a social structure that must at all times prove its viability in the world arena (and not with its inner logic, which is theoretically as total, as elegant, and plausible as that of any other society whatever), a practical politics that is in perpetual disequilibrium (and not with elaborate theories about the best form of government), a language that must constantly prove its creativity and capacity for adaptation in competition with other languages in an accelerating evolutionary situation (and not with a theory of the language at a given moment of its evolution). — Abdallah Laroui

It is a mistake to think of these men as visionary dreamers, playing around at Philadelphia with abstract conceptions of political theory, pulling a whole scheme of government out of the air like a rabbit out of a hat. True, many of them had read and studied enough about the science of politics to put the average statesman of today to shame. But political science was to them an extremely practical topic of discussion, dealing with the extremely practical business of running a government
not, as today, a branch of higher learning reserved for the use of graduate students. — Fred Rodell

The three parts of the theory are analytical ability, the ability to analyze things to judge, to criticize. Creative, the ability to create, to invent and discover and practical, the ability to apply and use what you know. — Robert Sternberg

Just as some plants bear fruit only if they don't shoot up too high, so in practical arts the leaves and flowers of theory must be pruned and the plant kept close to its proper soil- experience. — Carl Von Clausewitz

In teaching, the other main problem related to type is the students' interest. Intuitives and sensing types differ greatly in what they find interesting in any subject even if they like, that is, are interested in, the same subjects. Intuitives like the principle, the theory, the why. Sensing types like the practical application, the what and the how. — Isabel Briggs Myers

Pfuel was one of those theoreticians who so love their theory that they lose sight of the theory's object - its practical application. His love of theory made him hate everything practical, and he would not listen to it. He was even pleased by failures, for failures resulting from deviations in practice from the theory only proved to him the accuracy of his theory. — Leo Tolstoy

It is necessary to master Marxist theory and apply it, master it for the sole purpose of applying it. If you can apply the Marxist-Leninist viewpoint in elucidating one or two practical problems, you should be commended and credited with some achievement. The more problems you elucidate and the more comprehensively and profoundly you do so, the greater will be your achievement. — Mao Zedong

I'm just interested in women's friendships generally. It always seems to me, and this is just my pet theory, that women are kind of at the sharp end of capitalism one way or another. Mainly because they buy everything. In a practical sense, women buy most things. They're always comparing - to friends, to famous people, to other people. An obsessive act of comparison. — Zadie Smith

Practical wisdom is only to be learned in the school of experience. Precepts and instruction are useful so far as they go, but, without the discipline of real life, they remain of the nature of theory only. — Samuel Smiles

History, practical experience, common sense and economic theory all agree: economic competition is probably one of the greatest ideas humans ever came up with. When people compete to achieve the same goal, great things seem to happen that otherwise would not. Things get done faster, cheaper, and better; new methods for lifting a weight or quenching a thirst are invented; the average guy ends up with more of the stuff he likes at a lower price than before. That is why, in the end, socialism collapsed like a rotten wall: it did not allow its people to compete and, as a result, it not only made their economic life miserable, but strangled their hearts and souls. — Michele Boldrin

This segregation is confirmed by the common stereotypes of these two disciplines and their representatives. While scientists are perceived as absentminded, casually dressed individuals who live in a refined world of abstract theory with little practical reality, lawyers are usually perceived as formally dressed people who are practically oriented, concentrating mainly on trivialities (such as negotiating their retaining fee) and engaging professionally in all sorts of nitty-gritty social intercourse - the kind of things that normal people, although worried by them, would rather not have to deal with themselves. — Fritjof Capra

The US has developed two coordinate governing classes: the one, called 'business,' building cities, manufacturing and distributing goods, and holding complete and autocratic power over the livelihood of millions; the other, called 'government,' concerned with preaching and exemplification of spiritual ideals, so caught in a mass of theory, that when it wished to move in a practical world it had to do so by means of a sub rosa political machine. — Thurman Arnold

Pfuel was one of those theorists who love their theory so dearly they lose sight of the aim of all theory, which is to work out in practice. He was so much in love with theory that he hated all practice and didn't want to know about it. He positively rejoiced in failure, because failure was due to practical infringements of his theory, which went to show how right the theory was. — Leo Tolstoy

Because the true perfection of a practical occupation consists not only in knowing the actual performance of the occupation but also in its explanation, why the work is done a in a particular way, and because the art of calculating is a practical occupation, it is clear that it is pertinent to concern oneself with the theory. — Gersonides

Based on personal experience and not just on theory, Prayerwalk, offers readers practical insights on how to get up, get moving, and get praying. The results can be life changing. — Robin Jones Gunn

No political party can possibly lead a great revolutionary movement to victory unless it possesses revolutionary theory and knowledge of history and has a profound grasp of the practical movement. — Mao Zedong

There are some people, nevertheless - and I am one of them - who think that the most practical and important thing about a man is still his view of the universe ... We think that for a general about to fight an enemy, it is important to know the enemy's numbers, but still more important to know the enemy's philosophy. We think the question is not whether the theory of the cosmos affects matters, but whether in the long run, anything else affects them. — G.K. Chesterton

It will be seen how subjectivism and objectivism, spiritualism and materialism, activity and suffering, only lose their antithetical character, and thus their existence, as such antitheses in the social condition; it will be seen how the resolution of the theoretical antitheses is only possible in a practical way, by virtue of the practical energy of men. Their resolution is therefore by no means merely a problem of knowledge, but a real problem of life, which philosophy could not solve precisely because it conceived this problem as merely a theoretical one. — Robert C. Tucker

The first business of philosophy is to account for things as they are; and till our theories will do this, they ought not to be the ground of any practical conclusion. — Thomas Malthus

All social life is essentially practical. All mysterious which lead theory to mysticism find their rational solution in human practice and in the comprehension of the practice. — Karl Marx

Electromagnetic theory and experiment gave us the telephone, radio, TV, computers, and made the internal combustion engine practical - thus, the car and airplane, leading inevitably to the rocket and outer-space exploration. — Gregory Benford

In recent philosophy there has been a growing awareness of the gap between the abstract principles proposed by philosophers and the ways in which people actually think. The kind of rationality admired in the theory of knowledge is idealization. In the real world people have to act on beliefs often based on fragmentary and unreliable evidence. — Jonathan Glover

All science has one aim, namely, to find a theory of nature. We have theories of races and of functions, but scarcely yet a remote approach to an idea of creation. We are now so far from the road to truth, that religious teachers dispute and hate each other, and speculative men are esteemed unsound and frivolous. But to a sound judgment, the most abstract truth is the most practical. Whenever a true theory appears, it will be its own evidence. Its test is, that it will explain all phenomena. Now many are thought not only unexplained but inexplicable; as language, sleep, madness, dreams, beasts, sex. — Ralph Waldo Emerson
