 I declare that man consists of one and the same rational soul conjoined to the body in a mysterious manner, and that it is by a certain wonderful and intelligible division that man himself is divided into two parts, in one of which he is created in the image and likeness of the Creator, and participates in no animality … while in the other he communicates with the animal nature and was produced out of the earth, that is to say, out of the common nature of all things, and is included in the universal genus of animals. (Periphyseon, IV.754a–b)
