“The author of human nature impressed it with certain sensitive aptitudes and mental powers, so that apprehension, reflection or understanding could no otherwise be exerted or produced in the compound nature of man, but in the order prescribed by the creator.”

Original: L’ordre naturel n’est pas une invention de l’esprit humain et une mise en place de certaines propriétés d’observation... Qui dit ordre dit intelligence organisatrice. Cette intelligence ne peut être que celle de Dieu.

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.
