MacKenna-Plotinus: interior man

And Friendship? This emotion belongs sometimes to the lower part, sometimes to the interior man. Enneads   I,1,10

Now just as these three exist for the system of Nature, so, we must hold, they exist for ourselves. I am not speaking of the material order - all that is separable - but of what lies beyond the sense realm in the same way as the Primals are beyond all the heavens; I mean the corresponding aspect of man, what Plato calls the Interior Man. Enneads V,1,10
