Practical Vs. Theoretical Quotes & Sayings

Isolated facts and experiments have in themselves no value, however great their number may be. They only become valuable in a theoretical or practical point of view when they make us acquainted with the law of a series of uniformly recurring phenomena, or, it may be, only give a negative result showing an incompleteness in our knowledge of such a law, till then held to be perfect. — Hermann Von Helmholtz

If you find that you're spending almost all your time on theory, start turning some attention to practical things; it will improve your theories. If you find that you're spending almost all your time on practice, start turning some attention to theoretical things; it will improve your practice. — Donald Knuth

The word "ungodly and word-group" in Jude...It describes, not theoretical atheism, but practical godlessness. — Richard Bauckham

The most dangerous type of atheism is not theoretical atheism, but practical atheism -that's the most dangerous type. And the world, even the church, is filled up with people who pay lip service to God and not life service. And there is always a danger that we will make it appear externally that we believe in God when internally we don't. We say with our mouths that we believe in him, but we live with our lives like he never existed. That is the ever-present danger confronting religion. That's a dangerous type of atheism. — Martin Luther King Jr.

We must recognize the fact that philosophy at the present time is entirely at an impasse concerning the problem of the origin of values. This theoretical failure is reflected in the practical antinomy between submission and rebellion that infects the daily concerns of education, politics, and ethics. If no decision can be made at this level, we must retrace our steps, extricate ourselves from the impasse, and try to gain access, by means of a nonethical approach, to the problem of autonomy and obedience. — Paul Ricoeur

So far I have been speaking of theoretical science, which is an attempt to understand the world. Practical science, which is an attempt to change the world, has been important from the first, and has continually increased in importance, until it has almost ousted theoretical science from men's thoughts. — Bertrand Russell

Reason drives your search to make sense of the world by pushing you to ask why things are as they are. For theoretical reason, the outcome of that search becomes science; for practical reason, the outcome is a more just world. — Susan Neiman

It is not paradox to say that in our most theoretical moods we may be nearest to our most practical applications. — Alfred North Whitehead

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

Parking Reform Made Easy provides both a theoretical framework and practical methods for reforming parking requirements. By giving planners a sound basis for developing reforms, Richard Willson remedies the problem that many planners feel unqualified to challenge and change long-standing minimum parking requirements. — Donald Shoup

In some strata of Greek and Roman society the engineer was actually denigrated, higher esteem being accorded to poets, playwrights and sculptors. According to Plutarch, Archimedes was praised for refusing to contaminate his theoretical and mathematical science with practical applications, although under extreme pressure at the siege of Syracuse in Sicily he did design practical machinery. — Stephanie Dalley

[Theology] may be defined, the doctrine or science of the truth which is according to godliness, and which God has revealed to man that he may know God and divine things, may believe on Him and may through faith perform to Him the acts of love, fear, honour, worship and obedience, and obtain blessedness from Him through union with Him, to the divine glory ... On this account, theology is not a theoretical science or doctrine, but a practical one, requiring the action of the whole man, according to all and each of it's parts
an action of the most transcendent description, answerable to the excellence of the object as far as the human capacity will permit. — James Arminius

There is scarcely a subject that cannot be mathematically treated and the effects calculated or the results determined beforehand from the available theoretical and practical data. — Nikola Tesla

All the questions discussed in the Talmud and related rabbinic literature are normative questions: either they are questions of what one is to think or what one is to do. Every prescribed thought has some practical implication; every prescribed act has some theoretical implication. — David Novak

Routledge Performance Practitioners is an innovative series of introductory handbooks on key figures in twentieth-century performance practice. Each volume focuses on a theater-maker whose practical and theoretical work has in some way transformed the way we understand theater and performance. — Karen K. Bradley

Thus not only the mental and the material, but the theoretical and the practical in the mathematical world, are brought into more intimate and effective connection with each other. — Ada Lovelace

He has no interest in pursuing an abstract argument to demonstrate a purely theoretical truth. His practical reason is ethical. Its first principle could be stated thus: Do no evil, Take up what is good, Purify the mind - This is the teaching of buddhas.11 In seeing conditioned arising as a "ground," Gotama implies that insight into conditionality provides "grounds" on which to act. — Stephen Batchelor

An important contribution to a much-neglected but very important subject. No other author has set out to do what Davenport accomplishes, which is a systematic study of how key representatives of America's rising tide of religion attempted a theoretical understanding of, and practical response to, America's rising tide of commerce. — Mark Noll

We read many books, but that does not bring us knowledge. We may read all the Bibles in the world, but that will not give us religion. Theoretical religion is easy enough to get, any one may get that. What we want is practical religion. — Swami Vivekananda

The greatest cost of the specialization of technological life - and out of which all other damages are birthed - is arguably our separation from the practical and enriching sense of ourselves as embodied beings. When we are alienated from the wisdom of the body, our lives become theoretical and abstract, and we are distanced from the direct, felt sense of living. — Richard Strozzi-Heckler

What is the central core of the subject [computer science]? What is it that distinguishes it from the separate subjects with which it is related? What is the linking thread which gathers these disparate branches into a single discipline. My answer to these questions is simple -it is the art of programming a computer. It is the art of designing efficient and elegant methods of getting a computer to solve problems, theoretical or practical, small or large, simple or complex. It is the art of translating this design into an effective and accurate computer program. — Tony Hoare

on it, lose all practical value and all theoretical justification. Therefore, although the originators of these systems were, in many respects, revolutionary, their disciples have, in every case, formed mere reactionary sects. They hold fast by the original views of their masters, in opposition to the progressive historical development of the proletariat. They, — Friedrich Engels

You may be theoretically rich but practically poor. — Pushpa Rana

America is the only nation in the world that is founded on a creed. That creed is set forth with dogmatic and even theological lucidity in the Declaration of Independence; perhaps the only piece of practical politics that is also theoretical politics and also great literature. It enunciates that all men are equal in their claim to justice, that governments exist to give them that justice, and that their authority is for that reason just. It certainly does condemn anarchism, and it does also by inference condemn atheism, since it clearly names the Creator as the ultimate authority from whom these equal rights are derived. Nobody expects a modern political system to proceed logically in the application of such dogmas, and in the matter of God and Government it is naturally God whose claim is taken more lightly. The point is that there is a creed, if not about divine, at least about human things. — G.K. Chesterton

We must take the abiding spiritual values which inhere in the deep experiences of religion in all ages and give them new expression in terms of the framework which our new knowledge gives us. Science forces religion to deal with new ideas in the theoretical realm and new forces in the practical realm. — Harry Emerson Fosdick

Theoretical principals must sometimes give way for the sake of practical advantages. — William Pitt

The fear of speculation, the ostensible rush from the theoretical to the practical, brings about the same shallowness in action that it does in knowledge. It is by studying a strictly theoretical philosophy that we become most acquainted with Ideas, and only Ideas provide action with energy and ethical significance. — Friedrich Wilhelm Joseph Schelling

Being on the frontier, as I've said, required doing rather than imagining: clearing land, building shelter, obtaining food supplies. Frontiers test ideologies like nothing else. There is no time for the theoretical. That, ultimately, is why America has not been friendly to communism, fascism, or other, more benign forms of utopianism. Idealized concepts have rarely taken firm root in America, and so intellectuals have had to look to Europe for inspiration. People here are too busy making money - an extension, of course, of the frontier ethos, with its emphasis on practical initiative. — Robert D. Kaplan

A Critique of pure Reason, i.e. of our faculty of judging a priori according to principles, would be incomplete, if the Judgement, which as a cognitive faculty also makes claim to such principles, were not treated as a particular part of it; although its principles in a system of pure Philosophy need form no particular part between the theoretical and the practical, but can be annexed when needful to one or both as occasion requires. — Immanuel Kant

An open mind, in questions that are not ultimate, is useful. But an open mind about the ultimate foundations either of Theoretical or of Practical Reason is idiocy. If a man's mind is open on these things, let his mouth at least be shut. He can say nothing to the purpose. Outside the Tao there is no ground for criticizing either the Tao or anything else. — C.S. Lewis
