In theory there is no difference between theory and practice; in practice there is.
Einsteins relativity work is a magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors. The theory is like a beggar clothed in purple whom ignorant people take for a king... its exponents are brilliant men but they are metaphysicists rather than scientists.nikola tesla
Cicero is hardly to be reckoned ...for he delighted so much more in the practice, than in the theory, of his art, that he is perpetually drawn off from the rigid philosophical analysis of its principles, into discursive declamations, always eloquent indeed, and often highly interesting, but adverse to regularity of system, and frequently as unsatisfactory to the practical student as to the Philosopher.Richard Whately
The history of biology is littered with horrifying examples of the misuse of genetics (and evolutionary theory) to justify power and inequality: evolutionary justifications for slavery and colonialism, scientific explanations for rape and patriarchy, and genetic explanations for the inherent superiority of the ruling elite.
The chronological inconsistencies are perhaps most clearly exemplified by the writings of Nicole Oresme. In his Traictie de la Premierere Invention des Monnies, written about 1360, he develops a theory of money which reveals a very different approach to economic problems from that of his fellow Churchmen.roll, eric, baron roll of ipsden
ANARCHISM (from the Gr. , and , contrary to authority), the name given to a principle or theory of life and conduct under which society is conceived without government harmony in such a society being obtained, not by submission to law, or by obedience to any authority, but by free agreements concluded between the various groups, territorial and professional, freely constituted for the sake of production and consumption, as also for the satisfaction of the infinite variety of needs and aspirations of a civilized being.
If Edison had a needle to find in a haystack, he would proceed at once with the diligence of the bee to examine straw after straw until he found the object of his search. ... I was a sorry witness of such doings, knowing that a little theory and calculation would have saved him ninety per cent of his labor.nikola tesla
In aesthetic theory it might be extremely difficult, if not quite impracticable, to draw a line between the canon of classicism, or regard for the archaic, and the canon of beauty.thorstein veblen
I can not evolve any concrete theory about painting.william baziotes
When scientists need to explain difficult points of theory, illustration by hypothetical example – rather than by total abstraction – works well (perhaps indispensably) as a rhetorical device. Such cases do not function as speculations in the pejorative sense – as silly stories that provide insight into complex mechanisms – but rather as idealized illustrations to exemplify a difficult point of theory. (Other fields, like philosophy and the law, use such conjectural cases as a standard device.)stephen jay gould
It is a fatal defect of current principles of administration that, like proverbs, they occur in pairs. For almost every principle one can find an equally plausible and acceptable contradictory principle. Although the two principles of the pair will lead to exactly opposite recommendations, there is nothing in the theory to indicate which is the appropriate one to apply.
We are a moderate, pragmatic people, more comfortable with practice than theory.
Once we see, however, that the probability of life originating at random is so utterly miniscule as to make it absurd, it becomes sensible to think that the favorable properties of physics on which life depends are in every respect deliberate ... . It is therefore almost inevitable that our own measure of intelligence must reflect ... higher intelligences ... even to the limit of God ... such a theory is so obvious that one wonders why it is not widely accepted as being self-evident. The reasons are psychological rather than scientific.fred hoyle
In the Germany of the l920s, the Weimar Republic, both organismic biology and Gestalt psychology were part of a larger intellectual trend that saw itself as a protest movement against the increasing fragmentation and alienation of human nature. The entire Weimar culture was characterized by an antimechanistic outlook, a "hunger for wholeness". Organismic biology, Gestalt psychology, ecology, and, later on, general systems theory all grew out of this holistic zeitgeist.fritjof capra
A complete theory of evolution must acknowledge a balance between “external” forces of environment imposing selection for local adaptation and “internal” forces representing constraints of inheritance and development. Vavilov placed too much emphasis on internal constraints and downgraded the power of selection. But Western Darwinians have erred equally in practically ignoring (while acknowledging in theory) the limits placed on selection by structure and development what Vavilov and the older biologists would have called “laws of form.”stephen jay gould
[S]cientists are not robotic inducing machines that infer structures of explanation only from regularities observed in natural phenomena (assuming, as I doubt, that such a style of reasoning could ever achieve success in principle). Scientists are human beings, immersed in culture, and struggling with all the curious tools of inference that mind permits […]. Culture can potentiate as well as constrain as Darwin's translation of Adam Smith's laissez-faire economic models into biology as the theory of natural selection. In any case, objective minds do not exist outside culture, so we must make the best of our ineluctable embedding.stephen jay gould
To plead the organic causation of a religious state of mind, then, in refutation of its claim to possess superior spiritual value, is quite illogical and arbitrary, unless one have already worked out in advance some psycho-physical theory connecting spiritual values in general with determinate sorts of physiological change. Otherwise none of our thoughts and feelings, not even our scientific doctrines, not even our dis -beliefs, could retain any value as revelations of the truth, for every one of them without exception flows from the state of their possessor's body at the time.william james
Thompson and then his young men demolished a recurrent scientific myth one that had surfaced again in the 1870's: that there was nothing left to be discovered, nothing new under the sun. Part of the immutable wisdom of the day, endorsed and believed long before the greatest of scientists, Isaac Newton, was a kind of billiard ball theory of the atom, which went back to the ancient Greeks. The word itself is from the Greek atomos , meaning "inidivisible."j. j. thomson
Christians believed in a teleological cosmos, one created by an omniscient God, a Grand Designer, for a specific purpose. This comforting view was threatened by the new statistical methods in physics, and also by Darwin's theory of evolution, which assumes that chance may intervene between generations to introduce new characteristics.
Theories of genius are the peculiar constructions of our own philosophical times; ages of genius had passed away, and they left no other record than their works; no preconcerted theory described the workings of the imagination to be without imagination, nor did they venture to teach how to invent invention.isaac d'israeli
The important thing is what we do, and not the deceitful theory of reading others' intentions. This is also a new thing — they say: "We know that Iran's intention is to pursue nuclear weapons." Do you have a device that reads intentions?ali larijani
The best thing about being President is that it gets you out of American life. I don't know what the theory is behind this, but it is a fact. The first thing we do with a President is shunt him off to a siding where nothing American can ever happen to him.russell baker
In this crucial sense, the theory of punctuated equilibrium adopts a very conservative position. The theory asserts no novel claim about modes or mechanisms of speciation; punctuated equilibrium merely takes a standard microevolutionary model and elucidates its expected expression when properly scaled into geological time.stephen jay gould
The best case scenario is a rapid attack by precision-guided weapons, striking Saddam's communications in the first hours and preventing his deranged orders from being obeyed. Then a massive landing will bring food, medicine and laptop computers to a surging crowd of thankful and relieved Iraqis and Kurds. This could, in theory, all happen.christopher hitchens
In thermodynamics as well as in other branches of molecular physics , the laws of phenomena have to a certain extent been anticipated, and their investigation facilitated, by the aid of hypotheses as to occult molecular structures and motions with which such phenomena are assumed to be connected. The hypothesis which has answered that purpose in the case of thermodynamics, is called that of "molecular vortices," or otherwise, the "centrifugal theory of elasticity.william john macquorn rankine
There does seem to be among some members of our profession a rather desperate search for a "fundamental theory of information", which leads them to attempt to derive our practice from disciplines such as epistemology, or hermeneutics, or discourse analysis, or semiotics, or even "cybersemiotics". Their derivations rarely make adequate contact with the realities of information practice … The theory of a science should spring from deep immersion in its practice.
Protestantism itself, in its early phases, was plainly a movement toward mysticism: its purpose, at least in theory, was to remove the priestly veil separating man from the revealed Word of God. But that veil was restored almost instantly, and by the year 1522, five years after Wittenberg, Luther was damning the Anabaptists with all the ferocious certainty of a medieval Pope, and his followers were docily accepting his teaching.
A great deal of the thinking [in Organizational Development] has been influenced by cybernetics and information theory, though this has been used as much to extend the scope of closed-system as to improve the sophistication of open system formulations. It was von Bertalanffy (1950) who, in terms of the general transport equation which he introduced, first fully disclosed the importance of openness or closedness to the environment as a means of distinguishing living organisms from inanimate objects.
