“There is a Life-Principle of the world, a universal agent, wherein are two natures and a double current, of love and wrath. This ambient fluid penetrates everything. It is a ray detached from the glory of the sun, and fixed by the weight of the atmosphere and the central attraction. It is the body of the Holy Spirit, the universal Agent, the Serpent devouring his own tail. With this electro-magnetic ether, this vital and luminous caloric, the ancients and the alchemists were familiar. Of this agent, that phase of modern ignorance termed physical science talks incoherently, knowing naught of it save its effects; and theology might apply to it all its pretended definitions of spirit. Quiescent, it is appreciable by no human sense; disturbed or in movement, none can explain its mode of action; and to term it "fluid," and speak of its "currents," is but to veil a profound ignorance under a cloud of words.”
