You are asked to think of this Something as a great Ocean of Pure Mind, permeating all Space--between Solar Systems--between Worlds--between Masses of Substance--between the Molecules, Atoms, and Corpuscles. In and about and around everything--yes, even in Everything--in the very essence of the Corpuscle it is--in truth _it is that Essence itself_. Bound up in the bosom of that Mighty Ocean of Mind must reside all Knowledge of the Universe--of all "this side of God." For that All-Knowledge is but a knowing of its own region. Latent within itself must be locked up all Energy, or capacity for Force or Motion, for all Force or Energy is Mental. In its very presence it exemplifies the capacity of filling All Space. Omnipresent; Omnipotent; Omniscient--all the attributes of The Infinite are manifested in it--_and yet it is but the outward expression of That-Behind-the-Veil, which is the Causeless Cause of All_. In that Great Ocean of Universal or Cosmic Mind, bodies of Substance are but as floating specks of dust--_or even bubbles formed of the substance of that Ocean itself_--on the surface of that Ocean, there may arise waves, currents, ripples, eddies, whirlpools,--storms, hurricanes, tempests,--from its bosom may rise vapor, that after stages of clouds, rain-drops, flowing in streams, rivers, bays, at last again reach the source of its origin. These disturbances and changes we call Energy, Force, Motion--but they are but surface manifestations, and the Great Ocean is serene in its depths, and, in reality, is unchanged and undisturbed. This, friends, is that which the writer asks you to accept in the place of Aristotle's Ether. Is it a worthy exchange? * * * * * We have seen that the Attraction of Gravitation was different from any other so-called form of Force and Energy--both in its operations and laws, as well as in its constancy and self-support. And that it was different from the other forms of Attraction such as Cohesion, Chemical Affinity, etc. And, so we must consider it as more than a mere "Emotional Excitement" in the Mind of the Particle--that bubble on the surface of the Ocean. And it must be different from the special forms of Attraction manifested by the Atom and Molecule. It must be a simpler, more basic, and yet a more constant and permanent thing. It must exist before and after "Excitement; Vibration; Cohesion; and Chemical Affinity." _It must be the Mother of the Forces._
