The Summary of Physics Restored

201Light also displays to us the infinite nature of God. For the little flame of a lamp or candle cannot be exhausted or diminished by the tireless flow of its rays or by communicating its flame without limit, as long as its food remains. As many rays as it has, so many little streams flow from it. However much it gives and however much is taken from it, it is neither emptied nor suffers loss. This belongs to spiritual nature alone and is foreign to bodily nature. Intellectual gifts, such as the sciences and knowledge of things, which are rightly regarded as spiritual lights, are of this kind: however often communicated, they always remain whole in their possessor. We must acknowledge that there is something divine in light.
