Book excerpt: Life, whether in its latent or dynamic form, is Electricity, i.e., Force or “Spirit” moving Matter. Spirit is a bright flame within a transparent globule — its vehicle or soul. What we call light is an impression produced upon the retina by the wave-like motion of the particles of matter. Light, like heat of which the former is the crown, is simply the ghost, the shadow of matter in motion, the boundless, eternal, Infinite Space–Motion– Duration, the Trinitarian essence of that which the Deists call God, and we — the One Element. Spirit and Matter are two poles of One Eternal Element; they are interdependent and mutually convertible. Force and Matter, Spirit and Matter, or Deity and Nature, though they may be viewed as opposite poles in their respective manifestations, in essence and in truth are One. Life is present as much in a dead as in a living body, in inorganic as in organic matter.
