In theory there is no difference between theory and practice; in practice there is.
A good simulation, be it a religious myth or scientific theory, gives us a sense of mastery over experience. To represent something symbolically, as we do when we speak or write, is somehow to capture it, thus making it one's own. But with this appropriation comes the realization that we have denied the immediacy of reality and that in creating a substitute we have but spun another thread in the web of our grand illusion.Heinz R(udolf) Pagels
To build a theory of international relations on accidents of geography and history is dangerous.kenneth waltz
The theory says a lot, but does not really bring us any closer to the secret of the 'old one'. I, at any rate, am convinced that He does not throw dice.
For a parallel to the lesson of atomic theory regarding the limited applicability of such customary idealizations, we must in fact turn to quite other branches of science, such as psychology , or even to that kind of epistemological problems with which already thinkers like Buddha and Lao Tzu have been confronted, when trying to harmonize our position as spectators and actors in the great drama of existence.niels bohr
Any attempt to define literary theory in terms of a distinctive method is doomed to failure.terry eagleton
Monotheistic religions in the West have tended to conflate having a general orientation in life, having a specific theory of the world, having a sense of the positive meaningfulness of one’s existence, and having a fixed set of rules for behavior, but these elements are in principle separable. ... The “metaphysical need,” ... both Marx and Nietzsche held, is a historical phenomenon that arises under determinate circumstances, and could be expected to disappear under other circumstances that we could relatively easily envisage.raymond geuss
Each worldview was a cultural product, but evolution is true and separate creation is not. […] Worldviews are social constructions, and they channel the search for facts. But facts are found and knowledge progresses, however fitfully. Fact and theory are intertwined, and all great scientists understand the interaction.stephen jay gould
An old French mathematician said: A mathematical theory is not to be considered complete until you have made it so clear that you can explain it to the first man whom you meet on the street. This clearness and ease of comprehension, here insisted on for a mathematical theory, I should still more demand for a mathematical problem if it is to be perfect; for what is clear and easily comprehended attracts, the complicated repels us.david hilbert
The theory of Communism may be summed up in the single sentence: Abolition of private property.karl marx
Democracy is the theory that the common people know what they want, and deserve to get it good and hard.h. l. mencken
I would not want you to suppose that my rejection of Allen Forte's theory of pitch-class sets implies a rejection of the notion that there can be such a thing as a pitch-class set. It is only when one defines everything in terms of pitch-class sets that the concept becomes meaningless.george perle
A logical theory may be tested by its capacity for dealing with puzzles, and it is a wholesome plan, in thinking about logic, to stock the mind with as many puzzles as possible, since these serve much the same purpose as is served by experiments in physical science.bertrand russell
Neither natural ability without instruction nor instruction without natural ability can make the perfect artist. Let him be educated, skilful with the pencil, instructed in geometry, know much history, have followed the philosophers with attention, understand music, have some knowledge of medicine, know the opinions of the jurists, and be acquainted with astronomy and the theory of the heavens.vitruvius
Following Korzybski , I put things in probabilities, not absolutes ... My only originality lies in applying this zetetic attitude outside the hardest of the hard sciences, physics , to softer sciences and then to non-sciences like politics , ideology , jury verdicts and, of course, conspiracy theory .robert anton wilson
While in theory randomness is an intrinsic property, in practice, randomness is incomplete information .nassim nicholas taleb
This ascendancy of economic theory has not made the world a better place. Instead, it has made an already troubled society worse: more unequal, more unstable, and less 'efficient'.
In fact, an information theory that leaves out the issue of noise turns out to have no content.
The truth is Darwinism is not a scientific theory, but a materialistic creation myth masquerading as science. It is first and foremost a weapon against religion – especially traditional Christianity. Evidence is brought in afterwards, as window dressing.
Game theory can be defined as the study of mathematical models of conflict and cooperation between intelligent rational decision-makers.
According to the theory of aerodynamics, as may be readily demonstrated through wind tunnel experiments, the bumblebee is unable to fly. This is because the size, weight and shape of his body in relation to the total wingspread make flying impossible. But the bumblebee, being ignorant of these scientific truths, goes ahead and flies anyway and makes a little honey every day.
What I consider completely sterile is the attitude, for instance, of Bertalanffy who is going around and jumping around for years saying that all the analytical science and molecular biology doesn’t really get to interesting results; let’s talk in terms of general systems theory ... there cannot be anything such as general systems theory, it’s impossible. Or, if it existed, it would be meaningless.
The term hermeneutics covers both the first order art and the second order theory of understanding and interpretation of linguistic and non-linguistic expressions.
Physicists use the wave theory on Mondays, Wednesdays and Fridays and the particle theory on Tuesdays, Thursdays and Saturdays
"As flowing rivers disappear in the sea, losing their name and form, thus a wise man, freed from name and form, goes to the divine person who is beyond all." Such a theory of life and death will not please Western man, whose religion is as permeated with individualism as are his political and economic institutions. But it has satisfied the philosophical Hindu mind with astonishing continuity.
