Good theories of the mind must span at least three different scales of time: slow, for the billions of years in which our brains have survivied; fast, for the fleeting weeks and months of childhood; and in between, the centuries of growth of our ideas through history.
On the side of physics, there were a few key figures in Oxford who realized, in all probability unlike the majority of their colleagues in the physics department, that physics without interpretation is only part of the story, and that theories like quantum mechanics need careful foundational reflection.harvey brown
Skepticism must go hand in hand with rationality. When theories are shown to be false, the correct thing to do is to move on.brian cox
"I think the art of filmmaking is something you learn through actions, by doing it, not by learning theories. And as you do it, your mind starts to change."alejandro jodorowsky
Sometimes one can improve the theories in the sense of discovering a quicker, more efficient way of doing a given calculation.
Closely related to the erroneous idea that science is a body of knowledge is the equally erroneous idea that scientific theories are true.carroll quigley
As I said in another connection: "An excellent plumber is infinitely more admirable than an incompetent philosopher. The society which scorns excellence in plumbing because plumbing is a humble activity and tolerates shoddiness in philosophy because it is an exalted activity will have neither good plumbing nor good philosophy. Neither its pipes nor its theories will hold water".
For the theory-practice iteration to work, the scientist must be, as it were, mentally ambidextrous; fascinated equally on the one hand by possible meanings, theories, and tentative models to be induced from data and the practical reality of the real world, and on the other with the factual implications deducible from tentative theories, models and hypotheses.george e. p. box
My main professional interest during the 1970s has been in the dramatic change of concepts and ideas that has occurred in physics during the first three decades of the century, and that is still being elaborated in our current theories of matter. The new concepts in physics have brought about a profound change in our world view; from the mechanistic conception of Descartes and Newton to a holistic and ecological view, a view which I have found to be similar to the views of mystics of all ages and traditions.fritjof capra
A scientist, an artist, a citizen is not like a child who needs papa methodology and mama rationality to give him security and direction, he can take care of himself, for he is the inventor not only of laws, theories, pictures, plays, forms of music, ways of dealing with his fellow man, institutions, but also entire world view, he is the inventor of entire forms of like.paul karl feyerabend
According to the most influential twentieth-century philosopher of science, Karl Popper, a theory is scientific only in so far as it is falsifiable, and should be given up as soon as it has been falsified. By this standard, the theories of Darwin and Einstein should never have been accepted.john n. gray
It is essential to grasp the incontestable truth that a Marxist must take cognisance of real life, of the true facts of reality , and not cling to a theory of yesterday, which, like all theories, at best only outlines the main and the general, only comes near to embracing life in all its complexity.
I am a firm believer in intelligent design as a matter of faith and intellect, and I believe it should be presented in schools alongside the theories of evolution.rick perry
Geometry... is of much assistance in architecture, and in particular it teaches us the use of the rule and compasses, by which especially we acquire readiness in making plans for buildings in their grounds, and rightly apply the square, the level, and the plummet. By means of optics... the light in buildings can be drawn from fixed quarters of the sky. ...Difficult questions involving symmetry are solved by means of geometrical theories and methods.vitruvius
Truth does not need argument, agreement, theories or beliefs. There is only one test for it and that is to ask yourself 'Is the statement true or false in my experience?'
There are two kinds of thinkers, scholars and scientists. The first are the 'trail blazers' who propose new revolutionary ideas, point to new directions for scientific and intellectual developments, create new paradigms of science and scholarship, but leave the details to others. The second are those who follow the new trail, carry out careful experimentation and research within the established paradigm, and work out the precise formulations of theories in a particular domain of knowledge.
Progress in science is often built on wrong theories that are later corrected. It is better to be wrong than to be vague.freeman dyson
Strange as these words may sound I often play with the idea that when all the social theories collapse and wars and revolutions leave humanity in utter gloom, the poet whom Plato banned from his Republic may rise up to save us all.
Now these two questions Does there exist a material reality distinct from sensible appearances? and What is the nature of reality? do not have their source in experimental method, which is acquainted only with sensible appearances and can discover nothing beyond them. The resolution of these questions transcends the methods used by physics; it is the object of metaphysics. Therefore, if the aim of physical theories is to explain experimental laws, theoretical physics is not an autonomous science; it is subordinate to metaphysics.pierre duhem
A basic assumption within these theories is that organizations are complex adaptive systems (Anderson, 1999; Axelrod and Cohen, 1999), composed of semiautonomous agents that seek to maximize fitness by adjusting interpretative and action-oriented schema that determine how they view and interact with other agents and the environment.
It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.
Architects who have aimed at acquiring manual skill without scholarship have never been able to reach a position of authority to correspond to their pains, while those who relied only upon theories and scholarship were obviously hunting the shadow, not the substance. But those who have a thorough knowledge of both, like men armed at all points, have the sooner attained their object and carried authority with them.

Koyré's exaltation of the " Platonic and Pythagorean" elements of the Scientific Revolution... was based on a demonstrably false understanding of how Galileo reached his conclusions. Koyré asserted that Galileo merely used experiments as a check on the theories he devised by mathematical reasoning. But later research has definitively established that Galileo's experiments preceeded his attempts to give a mathematical account of their results.
theories which are logically self-contradictory may be significant and fruitful just in so far as their self-contradictory.
