A Quote by William John Macquorn Rankine
Discrepancy between theory and practice, which in sound physical and mechanical science is a delusion, has a real existence in the minds of men; and that fallacy, through rejected by their judgments, continues to exert and influence over their acts.

Without theory, practice is but routine born of habit. Theory alone can bring forth and develop the spirit of invention. ... [Do not] share the opinion of those narrow minds who disdain everything in science which has not an immediate application. ... A theoretical discovery has but the merit of its existence: it awakens hope, and that is all. But let it be cultivated, let it grow, and you will see what it will become.
It becomes evident that when the Life-power awakens its mysterious activity at the beginning of a cycle of manifestation those vibrations which we recognise as sound come into existence before the more rapid pulsations of electricity and light. Thus modern science confirms the ancient occult teaching that sound is the root of physical existence. 'It is out of Sound that every form comes, and it is in Sound that every form lives.
There is no real teacher who in practice does not believe in the existence of the soul, or in a magic that acts on it through speech.
If we practice the science of yoga, which is useful to the entire human community and which yields happiness both here and hereafter - if we practice it without fail, we will then attain physical, mental, and spiritual happiness, and our minds will flood towards the Self.
There is a distinction, but no opposition, between theory and practice. Each to a certain extent supposes the other. Theory is dependent on practice; practice must have preceded theory.
Sound and sufficient reason falls, after all, to the share of but few men, and those few men exert their influence in silence.
The words 'theory' and 'practice' are of Greek origin; they carry our thoughts back to the ancient philosophers by whom they were contrived, and by whom they were also contrasted and placed in opposition, as denoting two mutually conflicting and mutually inconsistent ideas. ... [this fallacy] based on a double system of natural laws retarded for centuries the development of physical science, notably mechanics.
The profound unity of subjective existence and objective environment leads naturally to the idea that the life-force of one human being can affect other living beings and even the fundamental being of humankind as a whole. Furthermore, the minds of humankind fuse into one and exert a continuous influence, both physical and spiritual, on other living beings and on the whole of nature.
I believe without exception that theory follows practice. Whenever there is a conflict between theory and practice, theory is wrong. As far as I'm concerned, we make theories for what people have done.
Relativity was a highly technical new theory that gave new meanings to familiar concepts and even to the nature of the theory itself. The general public looked upon relativity as indicative of the seemingly incomprehensible modern era, educated scientists despaired of ever understanding what Einstein had done, and political ideologues used the new theory to exploit public fears and anxieties-all of which opened a rift between science and the broader culture that continues to expand today.
Democracy is beautiful in theory; in practice it is a fallacy.
Those who are enamoured of practice without science are like a pilot who goes into a ship without rudder or compass and never has any certainty of where he is going. Practice should always be based upon a sound knowledge of theory.
I believe that we learn by practice. Whether it means to learn to dance by practicing dancing or to learn to live by practicing living, the principles are the same. In each, it is the performance of a dedicated precise set of acts, physical or intellectual, from which comes shape of achievement, a sense of one's being, a satisfaction of spirit. One becomes, in some area, an athlete of God. Practice means to perform, over and over again in the face of all obstacles, some act of vision, of faith, of desire. Practice is a means of inviting the perfection desired.
In order to exert influence over people, there were other things that could be used besides love. Knowledge seemed to be an equally strong force, perhaps even stronger. Whoever possessed knowledge not only had power over the changeable passions of people, but also power over their thinking, over their minds, hearts and souls.
A century ago mainstream science was still quite happy to countenance vital and mental powers which had a 'downwards' causal influence on the physical realm in a straightforwardly interactionist way. It was only in the middle of the last century that science finally concluded that there are no such non-physical forces. At which point a whole pile of smart philosophers (Feigl, Smart, Putnam, Davidson, Lewis) quickly pointed out that mental, biological and social phenomena must themselves be physical, in order to produce the physical effects that they do.
The best road to correct reasoning is by physical science; the way to trace effects to causes is through physical science; the only corrective, therefore, of superstition is physical science.
