“Great philosophical systems are never produced in a scientific vacuum but usually follow the formation and completion of a scientific world-perspective.”

The Art of Magic (1891)
Context: No one regards the magician today as other than an ordinary man gifted with no extraordinary powers. The spectators come, not to be impressed with awe, but fully aware that his causes and effects are natural. They come rather as a guessing committee, to spy out the methods with which he mystifies. Hundreds of eyes are upon him. Men with more knowledge of the sciences than he come to trip and expose him, and to baffle their scrutiny is the study of his life. Long years of training and exercise alone will not make a magician. … There must be some natural aptitude for the art; it must be born in a man, and can never be acquired by rule. He must be alert both in body and in mind; cool and calculating to the movement of a muscle under all circumstances; a close student of men and human nature. To these qualifications he must add the rather incongruous quality of a mind turning on contradictions. With a scientific cause he must produce a seemingly opposite effect to that warranted by order and system.
I know of no life requiring such a series of opposite qualities as the magician's. And after the exercise of all these qualities I have named, resulting in the production of the most startling and novel results, the magician has not the satisfaction, like other men, of the enjoyment of his own product. He must be prepared to see it copied by others, or after a short time discovered by the public.

Context: As a path to the perception of a deeper, comprehensive reality, in which the experiencing individual is also sheltered, meditation, in its different forms, occupies a prominent place today. The essential difference between meditation and prayer in the usual sense, which is based upon the duality of creator-creation, is that meditation aspires to the abolishment of the I-you-barrier by a fusing of object and subject, of sender and receiver, of objective reality and self.
Objective reality, the world view produced by the spirit of scientific inquiry, is the myth of our time. It has replaced the ecclesiastical-Christian and mythical-Apollonian world view.
But this ever broadening factual knowledge, which constitutes objective reality, need not be a desecration. On the contrary, if it only advances deep enough, it inevitably leads to the inexplicable, primal ground of the universe: the wonder, the mystery of the divine — in the microcosm of the atom, in the macrocosm of the spiral nebula; in the seeds of plants, in the body and soul of people.

Einstein's special theory of relativity, which explains the indeterminateness of the frame of space and time, crowns the work of Copernicus who first led us to give up our insistence on a geocentric outlook on nature; Einstein's general theory of relativity, which reveals the curvature or non-Euclidean geometry of space and time, carries forward the rudimentary thought of those earlier astronomers who first contemplated the possibility that their existence lay on something which was not flat. These earlier revolutions are still a source of perplexity in childhood, which we soon outgrow; and a time will come when Einstein's amazing revelations have likewise sunk into the commonplaces of educated thought.
