PHYSIO-PHILOSOPHY. INTRODUCTION. CONCEPTION OF THE SCIENCE. 1. Philosophy, as the science which embraces the principles of the universe or world, is only a logical, which may perhaps conduct us to the real, conception. 2. The universe or world is the reality of mathematical ideas, or, in simpler language, of mathematics. 3. Philosophy is the recognition of mathematical ideas as constituting the world, or the repetition of the origin of the world in consciousness. 4, 5. Spirit is the motion of mathematical ideas. Nature, their manifestation. 6. The philosophy of Spirit is the representation of the movements of ideas in consciousness. 7. The philosophy of Nature that of the phenomena or manifestations of ideas in consciousness. 8. The world consists of two parts: of one apparent, real, or material; and one non-apparent, ideal, spiritual, in which the material is not present, or which is naught in relation to the material. 9. There are, accordingly, two parts or divisions of Philosophy, viz. Pneumato-and Physio-philosophy.
