intellection is apprehension apart from body, much more must there be a distinction between the body and the intellective principle: sensation for objects of sense, intellection for the intellectual object.
Plotinus grounds the soul-body distinction in an epistemological argument: because intellection transcends sensation and the body is partite while the sentient principle must be self-identical throughout, soul cannot be any form of body.
