“Science tells us that heat may be shown to develop electricity, electricity produce heat; and magnetism to evolve electricity, and vice versa. Motion, they tell us, results from motion itself, and so on, ad infinitum. This is the A B C of occultism and of the earliest alchemists. The indestructibility of matter and force being discovered and proved, the great problem of eternity is solved.”

“Electric and magnetic forces. May they live for ever, and never be forgot”
Electromagnetic Theory (1912), Volume III; p. 1; "The Electrician" Pub. Co., London.
Context: Electric and magnetic forces. May they live for ever, and never be forgot, if only to remind us that the science of electromagnetics, in spite of the abstract nature of its theory, involving quantities whose nature is entirely unknown at the present, is really and truly founded on the observations of real Newtonian forces, electric and magnetic respectively.
