Plotinos: Complete Works, v. 2 In Chronological Order,...

Are we compelled to remember sensations by sensibility, whether it be the same power which feels sensation, and which remembers sensation, or is it also discursive reason which conceives and remembers conceptions. But the men who reason the best are not those who also remember the best; and those who have equally delicate senses, do not all, on that account, have an equally good memory. On the contrary, some have delicate senses, while others have a good memory, without however being capable of perceiving equally well. On the other hand, if feeling and remembering be mutually independent, there will be (outside of sensibility) another power which will remember things formerly perceived by sensation, and this power will have to feel what it is to remember.148
