Herbert Spencer says: "An entire history of anything must include its appearance out of the imperceptible and its disappearance into the imperceptible. Be it a single object or a whole universe, any account which begins with it in a concrete form and leaves off with it in a concrete form is incomplete, since there remains an era of its knowable existence undescribed and unexplained." The simplest statement of this fact, according to my theory, is that all visible things come from the great invisible sea of electro-magnetism in which all things exist, which he calls the imperceptible, and are woven by magnetic attraction and the aggregation of billions of invisible atoms into visible forms. Then, after they have run their course as visible substances or organic forms, they are again dissolved back into this invisible sea of electro-magnetism. Just as water continually changes from solid and liquid to invisible vapor and back again, so nature continually renews and purifies her ever-changing molecules but changeless atoms, and builds up organic forms by magnetic attraction and dissolves them by electric repulsion. I contend that matter could be gathered into visible form in no other way than by electric attraction. The life period of all visible things is while magnetic attraction has sway and is paramount; the death or dissolution period is when electric repulsion predominates. The blossoms and fruitage of summer are samples of magnetic life from the sun currents, while the decay of winter is a sample of electric repulsion and dissolution. The law of incessant change, he says, must be the unifying principle which in its simplest form is "the redistribution of matter and motion." Again he says: "The progress from the most diffused and insensible state to that of concentration and definition is called evolution, and is attended by the dissipation of motion and the integration of matter." This I call the law of electric attraction. "The progress from the form of definition to that of diffusion," he says, "is called dissolution and is attended by an absorption of motion and a disintegration of matter." This I call the law of electric repulsion. "This," he says, "is the universal law of evolution and dissolution in its simplest form." And I say that the law of evolution and dissolution in its simplest form is the law of electric attraction and repulsion.
