that is, from the all-pervading Ether, our primeval home, the original form of Matter which fills space; the imponderable Ether in which the suns and systems float, having evolved with all that they contain from that very plasmic Ether. Again, all Matter having memory, and man being Matter grown conscious--a metaphysic for this would be the World as Memory rushing into Consciousness; but however that be expressed, man's idea of the Universe before he knows its true configuration or how it arose, is certain to contain some suggestion of the actual becoming of things; and that suggestion will naturally derive from subconscious recollections of impressive events in the history of Matter. In the history of the solar system after the unbegun period of its existence dissolved in the plasmic Ether, the first impressive event is electrical evolution, when the Matter of the sun and the planets overbrimmed solar space as a globular or spiral nebula. Every particle of earth was all luminous in that pristine light: the pen I write with, the paper I write on, my hand that writes, and my brain that instructs my hand. The next important event is the condensation and contraction of the nebula with the segregation of the planets, when all the chemical affinities, the energies of electricity and heat, radiative action, centrifugal and centripetal forces and the force of gravitation kept up for millions of years a war of the elements no atom of Matter can ever forget. The blood, the brain, the bones, the flesh, and the marrow, retaining an indelible impression of their placid existence in the unbegun Ether, of the diaphanous light of the nebula, and of the terrific time of infernal tumult when the solar system was evolved, suggested to man, when his highly developed consciousness begat a still unenlightened idea of the Universe, that splendour on high, his glowing Heaven of light, and that horror below, his fiery Hell of torment. This is pure poetry. Eloquence not being my purpose in this preface, I have expounded it in strict Matter-of-fact prose; but being Matter of Imagination all compact, a truer poetical form will be found in "The Testament of a Prime Minister." (pp. 98-100.) Heaven and Hell, then, are subconscious recollections of the peace of the Ether, of the glory of the nebula, and of the condensation and contraction suffered by the Matter of which man consists during the millions of millions of years of the evolution of the solar system, perdurable experiences impressed on every molecule, every atom, every electron of the globe and of man; and when I invite the imagination of the world to take up its abode in the actual poetry of Matter, it is a true devolution I desire, comparable to the return of Matter through vapour and lightning into the all-pervading Ether.
