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 Nazis entered this war under the rather childish delusion that they were going to bomb everyone else, and nobody was going to bomb them. At Rotterdam, London, Warsaw, and half a hundred other places, they put their rather naive theory into operation. They sowed the wind, and now they are going to reap the whirlwind.arthur travers harris
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.
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.
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
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
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.
If, of course, one builds into the concept of an 'individual' all that Professor Hayek does in his Road To Serfdom, Individualism and Economic Order and many other works, which is, to put it briefly, the whole of laisser-faire economic theory, then plainly man as such a programmed predator has very little interest in being fraternal, or very little chance.bernard crick
Human beings seem to be far more autonomous and self-governed than modern psychological theory allows for.abraham maslow
If quantum communication and quantum computation are to flourish, a new information theory will have to be developed.hans christian von baeyer
I work in the field of art, and you know how during a period of Marxist ideology, fewer people are inclined to believe in the power of the culture as a whole: they believe in the revolutionary potential of economics, class struggle theory...Therefore it’s time to show that art means the power of creativity, and it’s time to define art in a larger way, to include science and religion too.joseph beuys
Thou art greatly wise, my friend, and ever respected by me, yet I find not in your theory or your scope, room enough for the lyric inspirations, or the mysterious whispers of life. To me it seems that it is madder never to abandon oneself, than often to be infatuated; better to be wounded, a captive, and a slave, than always to walk in armor.margaret fuller
It is possible to express the laws of thermodynamics in the form of independent principles , deduced by induction from the facts of observation and experiment, without reference to any hypothesis as to the occult molecular operations with which the sensible phenomena may be conceived to be connected; and that course will be followed in the body of the present treatise. But, in giving a brief historical sketch of the progress of thermodynamics, the progress of the hypothesis of thermic molecular motions cannot be wholly separated from that of the purely inductive theory.william john macquorn rankine
Instead of ideologically synchronizing contradictions, or assigning them to separate halls of the academy, critical theory seeks to articulate them.
What, after all, is a better example of chaos theory than the harassment of a street vendor in Tunisia leading to a civil war in Syria?
Another curious aspect of the theory of evolution is that everybody thinks he understands it. I mean philosophers, social scientists, and so on. While in fact very few people understand it, actually, as it stands, even as it stood when Darwin expressed it, and even less as we now may be able to understand it in biology.Jacques Monod
