  • The problem of peaceful transition to socialism, we do not discuss it as a theoretical question. But in America it is very difficult, and it is nearly impossible. That is why specifically in America we say that the road to the liberation of peoples, which will be the road of socialism will go through bullets in almost all countries.

  • Economics was like psychology, a pseudoscience trying to hide that fact with intense theoretical hyperelaboration. And gross domestic product was one of those unfortunate measurement concepts, like inches or the British thermal unit, that ought to have been retired long before.

    Kim Stanley Robinson (2003). “Blue Mars”, p.105, Spectra
  • And then there is Pythagoras. The legend is that the founder of theoretical mathematics was so outraged when one of his students, the haplessly gifted Hippasus, discovered irrational numbers that he sent the poor fellow out on a raft to drown, initiating a venerable tradition of professors mistreating their graduate students.

    Rebecca Newberger Goldstein (2014). “Plato at the Googleplex: Why Philosophy Won't Go Away”, p.31, Atlantic Books Ltd
  • Long experience has taught me not always to believe in the limitations indicated by purely theoretical considerations. These, as we well know, are based on insufficient knowledge of all the relevant factors.

  • I had a theoretical reverence and homage for beauty, elegance, gallantry, fascination but had I met those qualities incarnate in masculine shape, I should have known instinctively that they had nor could have sympathy with anything in me.

    Charlotte Bronte, Emily Bronte, Anne Bronte (2009). “The Bronte Sisters: Three Novels: Jane Eyre; Wuthering Heights; and Agnes Grey (Penguin Classics Deluxe Edition)”, p.96, Penguin
  • Max Weber was right in subscribing to the view that one need not be Caesar in order to understand Caesar. But there is a temptation for us theoretical sociologists to act sometimes as though it is not necessary even to study Caesar in order to understand him. Yet we know that the interplay of theory and research makes both for understanding of the specific case and expansion of the general rule.

  • During the time that [Karl] Landsteiner gave me an education in the field of imununology, I discovered that he and I were thinking about the serologic problem in very different ways. He would ask, What do these experiments force us to believe about the nature of the world? I would ask, What is the most. simple and general picture of the world that we can formulate that is not ruled by these experiments? I realized that medical and biological investigators were not attacking their problems the same way that theoretical physicists do, the way I had been in the habit of doing.

  • If the facts don't fit the theory, change the facts.

    Albert Einstein (2010). “The Ultimate Quotable Einstein”, p.483, Princeton University Press
  • Since the beginning of physics, symmetry considerations have provided us with an extremely powerful and useful tool in our effort to understand nature. Gradually they have become the backbone of our theoretical formulation of physical laws.

    "Particle Physics and Introduction to Field Theory: Revised and Updated First Edition". Book by Tsung-Dao Lee, 1981.
  • Contrary to the legend, Darwin's finches do not appear to have inspired his earliest theoretical views on evolution, even after he finally became an evolutionist in 1837; rather it was his evolutionary views that allowed him, retrospectively, to understand the complex case of the finches.

  • The law is this: that each of our leading conceptions-each branch of our knowledge-passes successively through three different theoretical conditions: the Theological, or fictitious: the Metaphysical, or abstract; and the Scientific, or positive.

    Auguste Comte (1975). “Auguste Comte and Positivism: The Essential Writings”, p.68, Transaction Publishers
  • What I remember most clearly was that when I put down a suggestion that seemed to me cogent and reasonable, Einstein did not in the least contest this, but he only said, 'Oh, how ugly.' As soon as an equation seemed to him to be ugly, he really rather lost interest in it and could not understand why somebody else was willing to spend much time on it. He was quite convinced that beauty was a guiding principle in the search for important results in theoretical physics.

  • A number of current theoretical explorations will turn out to be passing fancies...

    "Inward Bound : Of Matter and Forces in the Physical World" by Abraham Pais, (p. 45), 1988.
  • All theoretical chemistry is really physics; and all theoretical chemists know it.

  • Our hypotheses are initially rooted in theoretical consistency and elegance, but...ultimatel y it is experiment not rigid belief that determines what is correct.

  • Outside of mathematics and logic, there are common sense truths, such as that it is snowing that normal observers, in a specified context can agree on, subject to vagueness considerations, and theoretical truths, such as that snow is crystallised water vapour, and maybe in-between truths.

  • I see anarchism as the theoretical ideal to which we are all gradually evolving to a point where everybody can tell the truth to everybody else and nobody can get punished for it. That can only happen without hierarchy and without people having the authority to punish other people.

  • But, contrary to the lady's prejudices about the engineering profession, the fact is that quite some time ago the tables were turned between theory and applications in the physical sciences. Since World War II the discoveries that have changed the world are not made so much in lofty halls of theoretical physics as in the less-noticed labs of engineering and experimental physics. The roles of pure and applied science have been reversed; they are no longer what they were in the golden age of physics, in the age of Einstein, Schrödinger, Fermi and Dirac.

  • 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.

  • Consequently, the sensuous aspect of art is related only to the two theoretical sensesof sight and hearing, while smell, taste, and touch remain excluded.

    Georg Wilhelm Friedrich Hegel (1998). “Aesthetics: Lectures on Fine Art”, p.38, Oxford University Press
  • I had always been very rational, but I'd always used reason in such a way as to convince myself that reasoning alone would not solve anything, really. Reasoning is theoretical. Until you feel with your heart, you don't know if a thing is true. I found that book was absolutely authentic. I absolutely knew it was the truth. My whole heart accepted it.

  • This is the key of modern science and is the beginning of the true understanding of nature. This idea. That to look at the things, to record the details, and to hope that in the information thus obtained, may lie a clue to one or another of a possible theoretical interpretation.

  • The only purpose of education is to teach a student how to live his life-by developing his mind and equipping him to deal with reality. The training he needs is theoretical, i.e., conceptual. He has to be taught to think, to understand, to integrate, to prove. He has to be taught the essentials of the knowledge discovered in the past-and he has to be equipped to acquire further knowledge by his own effort.

    Ayn Rand (1988). “The Ayn Rand Lexicon: Objectivism from A to Z”, p.154, Penguin
  • The test is can you do something, rather than have a theoretical argument - can you make a difference?

  • To avert the danger [posed by theory] to life, Nietzsche could choose one of two ways: he could insist on the strictly esoteric character of the theoretical analysis of life - that is, restore the Platonic notion of the noble delusion - or else he could deny the possibility of theory proper and so conceive of thought as essentially subservient to, or dependent on, life or fate... If not Nietzsche himself, at any rate his successors [Heidegger] adopted the second alternative.

  • The facile economic and psychological debunking of the theoretical life cannot do away with its irreducible beauties.

    Allan Bloom (2008). “Closing of the American Mind”, p.245, Simon and Schuster
  • The problem of an eidos in history, hence, arises only when a Christian transcendental fulfillment becomes immanentized. Such an immanentist hypostasis of the eschaton, however, is a theoretical fallacy.

    Eric Voegelin, James L. Wizer (1998). “The Collected Works of Eric Voegelin”, p.185, University of Missouri Press
  • Experience arises together with theoretical assumptions not before them, and an experience without theory is just as incomprehensible as is (allegedly) a theory without experience.

    Paul Feyerabend (1993). “Against Method”, p.149, Verso
  • I don’t have a theoretical language for music. I’m really inspired by sculpture, so I like to say, ‘you’re not making music, you’re creating a space. You’re building a room, putting some objects in it, and seeing what happens to the objects over time.’

  • From it genesis twelve hundred years ago to today, Islamic philosophy (al-hikmah; al-falsafah) has been one of the major intellectual traditions within the Islamic world, and it has influenced and been influenced by many other intellectual perspectives, including Scholastic theology (kalam) and doctrinal Sufism (al-ma'rifah or al-tasawwuf al-'ilmi) and theoretical gnosis ('irfan-i nazari).
