ONLY THE PHYSICAL ORGANS, NOT THE IMMATERIAL NATURES, COULD BE AFFECTED.
Project Gutenberg EPUB3 edition
Plotinus and Guthrie, Kenneth Sylvan
In general, the actualizations of immaterial (natures) do not in any way imply that these (natures) were altered—which would imply their destruction—but, on the contrary, they remain what they were. Only material things are affected, while active. If an immaterial principle were exposed to undergo affections, it would no longer remain what it is. Thus in the act of vision, the sight acts, but it is the eye that is affected. As to opinions, they are actualizations analogous to sight.
