G. W. F. Hegel, Lectures on the Proofs of the Existence of God…
“ When in the course of knowledge we advance from Nature to Spirit, and Nature is defined as simply a moment of Spirit, we do not reach a true multiplicity, a substantial two, the one of which would be Nature, and the other Spirit; but, on the contrary, the Idea which is the substance of Nature, having taken on the deeper form of Spirit, retains in itself that content in this infinite intensity of ideality, and is all the richer because of the determination of this ideality itself, which is in-and-for-itself, self-conscious, or Spirit. ”
