All life moves in rhythm. We know to-day that the old distinctions between spirit and matter are superficial. When I was a student at the School of Mines at the age of seventeen, learning organic and inorganic chemistry, we were taught Mendeléeff’s Law which showed that all the elements were multiples of a common denominator, the atom; and since then it has been discovered that instead of the atom being the smallest possible bit of matter, finite and irreducible, it is a solar system--its sun and planets being bits of positive and negative electricity. All that is left of the whole structure of nineteenth century materialism has crumbled away to that word “bits.” We cannot as yet imagine or think without resting somewhere on “bits.” Our minds like our feet need a solid something beneath them. It is paralysing to conceive that the floor we stand upon, the chair we sit upon, consist solely of rotating electrical forces, but when we think of “bits” welded together we feel safe again, although actually these “bits” are a pure mental fiction, and what we stand and sit upon is _motion_. If the motion stopped we should fall into the bottomless pit, the famous vacuum abhorred of Nature (alias Tophet in biblical language). My chemistry teachers would have been as scandalized to think that at the bottom of their inorganic and organic chemistry there was nothing but motion, as my music teachers would have been scandalized to think that at the bottom of the major and minor scales there was nothing but love. They imagined that these were two entirely different worlds with an infinite chasm between them. They thought that inorganic chemistry was absolutely different from organic chemistry, although of course they would have got into a hopeless muddle had they tried to prove their belief--but then only fools and geniuses try to prove their beliefs. Neither my chemistry nor my music teachers could ever explain anything. One was simply asked to swallow whole and regurgitate whole what was obviously mere unintelligible rigmarole. Those of us who had this parrot-like faculty became in our turn Professors of Chemistry and of Music.
