Gregory Thaumaturgus

“ And besides, if the soul is a body, it has sensible qualities, and is maintained by nurture. But it is not thus nurtured. For if it is nurtured, it is not nurtured corporeally, like the body, but incorporeally; for it is nurtured by reason. It has not, therefore, sensible qualities: for neither is righteousness, nor courage, nor any one of these things, something that is seen; yet these are the qualities of the soul. It cannot, therefore, be a body, but is incorporeal. ”
