In theory there is no difference between theory and practice; in practice there is.
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
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 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
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.
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
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.
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
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
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
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
At any one time there is a natural tendency among physicists to believe that we already know the essential ingredients of a comprehensive theory. But each time a new frontier of observation is broached we inevitably discover new phenomena which force us to modify substantially our previous conceptions. I believe this process to be unending, that the delights and challenges of unexpected discovery will continue always.val logsdon fitch
Like all of mathematics, game theory is a tautology whose conclusions are true because they are contained in the premises.thomas flanagan
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
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
Jurgen Habermas is widely considered as the most influential thinker in Germany over the past decade. As a philosopher and sociologist he has mastered and creatively articulated an extraordinary range of specialized literature in the social sciences, social theory and the history of ideas in the development of a comprehensive and provocative critical theory of knowledge and human interests. His roots are in the tradition of German thought from Kant to Marx , and he has been associated with the Frankfurt School of critical theorists which pioneered in the study of the relationship of the ideas of Marx and Freud .jürgen habermas
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
Instead of ideologically synchronizing contradictions, or assigning them to separate halls of the academy, critical theory seeks to articulate them.
The successes of modern control theory in the design of highly accurate space navigation systems have stimulated its use in the theoretical analyses of economic and biological systems. Similarly, the effectiveness of computer simulation techniques in the macroscopic analyses of physical systems has brought into vogue the use of computer-based econometric models for purposes of forecasting, economic planning, arid management.
Lack of specificity around stakeholder identity remains a serious obstacle to the further development of stakeholder theory and its adoption in actual practice by business managers . Nowhere is this shortcoming more evident than in stakeholder theory's treatment of the constituency known as 'community.
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
