Plotinus,
Plotinos: Complete Works, v. 2
“ Let us, in thought, embrace all beings: air, light, sun, and moon. Let us then consider the sun, the light, and so forth, as being all things, without ever forgetting that there are things that occupy the first rank, others the second, or the third. Let us, at the summit of this series of beings, conceive of the universal Soul as subsisting eternally. Let us then posit that which holds the first rank after her, and thus continue till we arrive at the things that occupy the last rank, and which, as it were, are the last glimmerings of the light shed by the soul. ”
