Practical Mental Influence

...light that no eye can see. The long, dark, soundless space between 40,000 and 400,000,000,000,000 vibrations per second—and the infinite range beyond 700,000,000,000,000 vibrations per second, where light ceases in the universe of motion—makes it possible to indulge in speculation.”

Professor Williams likely William Mattieu Williams (1820–1894), a popular science writer known for "The Fuel of the Sun", the well-known scientific writer, has said:

“There is no gradual transition original: "gradation" between the most rapid vibrations original: "undulations or tremblings" that produce our sensations of sound, and the slowest of those which give rise to our sensations of gentlest warmth. There is a huge gap between them, wide enough to include another world of motion, all lying between our world of sound and our world of heat and light. There is no good reason whatever for supposing that matter is incapable of such intermediate activity, or that such activity may not give rise to intermediate sensations, provided there are organs for taking up and perceiving original: "sensifying" their movements.”

And so you see that in the scientific theory of vibrations, there may be found plenty of room for a scientific explanation of all that is claimed by the followers original: "adherents" of the truth of Mental Influence. This is possible without leaving the realm of physical science and without entering the field of metaphysics metaphysics: a branch of philosophy that deals with the first principles of things, including abstract concepts such as being, knowing, and time. There are many more proofs from the same source, which we may touch upon as we proceed.
