Lorenz Oken,
Elements of Physiophilosophy
“ The activity of the æther or the light dies or becomes obscured in matter. The next obscuration of light, or its immediate transition into matter is the polar primary body, oxygen. Oxygen is the corporeal light. It is the spirit of light to posit every thing with an internal polarity, to convert everything into oxygen, to render everywhere free the oxygen pole; for the process of fixation can only happen through activity = light, and fixation is a production of primary bodies. ”
