The most dangerous tendency of the modern world is the way in which bogus theories are given the force of dogma.

The wise man regulates his conduct by the theories both of religion and science. But he regards these theories not as statements of ultimate fact but as art-forms.

Philosophy, like science, consists of theories or insights arrived at as a result of systemic reflection or reasoning in regard to the data of experience. It involves, therefore, the analysis of experience and the synthesis of the results of analysis into a comprehensive or unitary conception. Philosophy seeks a totality and harmony of reasoned insight into the nature and meaning of all the principal aspects of reality.

Theories without facts may be barren, but facts without theories are meaningless.

Many writers upon the science of political economy have declared that it is the duty of a nation first to encourage the creation of wealth; and second, to direct and control its distribution. All such theories are delusive.

Another instance of a realization that the superstitious belief in progress is insufficient as a guide to life, was my brother's death. Wise, good, serious, he fell ill while still a young man, suffered for more than a year, and died painfully, not understanding why he had lived and still less why he had to die. No theories could give me, or him, any reply to these questions during his slow and painful dying.

The continuity of our science has not been affected by all these turbulent happenings, as the older theories have always been included as limiting cases in the new ones.

There's no thinking involved in my choreography... I don't work through images or ideas. I work through the body... If the dancer dances, which is not the same as having theories about dancing or wishing to dance or trying to dance, everything is there. When I dance, it means: this is what I am doing.

Anachronistic as this labyrinthine mythology may appear to the foreign mind, many of India’s ancient theories about the universe are startlingly modern in scope and worthy of a people who are credited with the invention of the zero, as well as algebra and its application of astronomy and geometry; a people who so carefully observed the heavens that, in the opinion of Monier-Williams, they determined the moon’s synodical revolution much more correctly than the Greeks.

THEORY: In science, a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses. The contention that evolution should be taught as a "theory, not as a fact" confuses the common use of these words with the scientific use. In science, theories do not turn into facts through the accumulation of evidence. Rather, theories are the end points of science. They are understandings that develop from extensive observation, experimentation, and creative reflection. They incorporate a large body of scientific facts, laws, tested hypotheses, and logical inferences. In this sense, evolution is one of the strongest and most useful scientific theories we have.

No theory ever agrees with all the facts in its domain, yet it is not always the theory that is to blame. Facts are constituted by older ideologies, and a clash between facts and theories may be proof of progress. It is also a first step in our attempt to find the principles implicit in familiar observational notions.

Facts are constituted by older ideologies, and a clash between facts and theories may be proof of progress.

Not only are facts and theories in constant disharmony, they are never as neatly separated as everyone makes them out to be.

Progress was often achieved by a "criticism from the past"... After Aristotle and Ptolemy, the idea that the earth moves - that strange, ancient, and "entirely ridiculous", Pythagorean view was thrown on the rubbish heap of history, only to be revived by Copernicus and to be forged by him into a weapon for the defeat of its defeaters. The Hermetic writings played an important part in this revival, which is still not sufficiently understood, and they were studied with care by the great Newton himself. Such developments are not surprising. No idea is ever examined in all its ramifications and no view is ever given all the chances it deserves. Theories are abandoned and superseded by more fashionable accounts long before they have had an opportunity to show their virtues. Besides, ancient doctrines and "primitive" myths appear strange and nonsensical only because their scientific content is either not known, or is distorted by philologists or anthropologists unfamiliar with the simplest physical, medical or astronomical knowledge.

The material which a scientist actually has at his disposal, his laws, his experimental results, his mathematical techniques, his epistemological prejudices, his attitude towards the absurd consequences of the theories which he accepts, is indeterminate in many ways, ambiguous, and never fully separated from the historical background. This material is always contaminated by principles which he does not know and which, if known, would be extremely hard to test.

We have to realize that a unified theory of the physical world simply does not exist. We have theories that work in restricted regions, we have purely formal attempts to condense them into a single formula, we have lots of unfounded claims (such as the claim that all of chemistry can be reduced to physics), phenomena that do not fit into the accepted framework are suppressed; in physics, which many scientists regard as the one really basic science, we have now at least three different point of view (relativity, dealing with the very large, quantum theory for an intermediate domain and various particle models for the very small) without a promise of conceptual (and not only formal) unification; perceptions are outside of the material universe (the mind-body problem is still unsolved) - from the very beginning the salesman of a universal truth cheated people into admissions instead of clearly arguing for their philosophy. And let us not forget that it was they and not the representatives of the traditions they attacked who introduced argument as the one and only universal arbiter. They praised argument - they constantly violated its principles.

Commitment to the truth… means a relentless willingness to root out the ways we limit or deceive ourselves from seeing what is, and to continually challenge our theories of why things are the way they are. It means continually broadening our awareness. It also means continually deepening our understanding of the structures underlying current events.

Scientific theories based upon the truth of the senses tend, as we have seen, to become progressively materialistic, mechanistic, and quantitative, even in their interpretation of man, culture, and mental phenomena. The social and psychological sciences begin to imitate the natural sciences, attempting to treat man in the same way as physics and chemistry treat inorganic phenomena. In the field of the social sciences all mental and cultural phenomena come to be treated behavioristically, physiologically, "reflexologically", "endocrinologically", and psychoanalytically. Society becomes economically minded, and the "economic interpretation of history" begins to hold undisputed sway. A quasi-pornographic conception of human culture acquires a wide vogue, in biographies, history, anthropology, sociology, and psychology. Anything spiritual, supersensory, or idealistic is ridiculed, being replaced by the most degrading and debasing interpretations. All this is closely analogous to the negative, warped, subsocial, and psychopathic propensities exhibited by the fine arts during the decadent phase of sensate culture.

It is undeniable that when a mind enlightened and enriched with modern scientific knowledge weighs this problem calmly, it feels drawn to break through the circle of completely independent or autochthonous matter, whether uncreated or self-created, and to ascend to a creating Spirit. With the same clear and critical look with which it examines and passes judgment on facts, it perceives and recognizes the work of creative omnipotence, whose power, set in motion by the mighty "Fiat" pronounced billions of years ago by the Creating Spirit, spread out over the universe, calling into existence with a gesture of generous love matter bursting with energy. In fact, it would seem that present-day science, with one sweeping step back across millions of centuries, has succeeded in bearing witness to that primordial "Fiat lux" uttered at the moment when, along with matter, there burst forth from nothing a sea of light and radiation, while the particles of chemical elements split and formed into millions of galaxies. It is quite true that the facts established up to the present time are not an absolute proof of creation in time, as are the proofs drawn from metaphysics and Revelation in what concerns simple creation or those founded on Revelation if there be question of creation in time. The pertinent facts of the natural sciences, to which We have referred, are awaiting still further research and confirmation, and the theories founded on them are in need of further development and proof before they can provide a sure foundation for arguments which, of themselves, are outside the proper sphere of the natural sciences. This notwithstanding, it is worthy of note that modern scholars in these fields regard the idea of the creation of the universe as entirely compatible with their scientific conceptions and that they are even led spontaneously to this conclusion by their scientific research. Just a few decades ago, any such "hypothesis" was rejected as entirely irreconcilable with the present state of science. As late as 1911, the celebrated physicist Svante Arhenius declared that "the opinion that something can come from nothing is at variance with the present-day state of science, according to which matter is immutable." In this same vein we find the statement of Plato: "Matter exists. Nothing can come from nothing, hence matter is eternal. We cannot admit the creation of matter."

It must be conceded that a theory has an important advantage if its basic concepts and fundamental hypotheses are 'close to experience,' and greater confidence in such a theory is certainly justified. There is less danger of going completely astray, particularly since it takes so much less time and effort to disprove such theories by experience. Yet more and more, as the depth of our knowledge increases, we must give up this advantage in our quest for logical simplicity in the foundations of physical theory.
