29. Are we, then, to refer memory to the perceptive faculty and so make one principle of our nature the seat of both awareness and remembrance?
Now supposing the very Shade, as we were saying in the case of Hercules, has memory, then the perceptive faculty is twofold.
[(And if (on the same supposition) the faculty that remembers is not the faculty that perceives, but some other thing, then the remembering faculty is twofold.]
And further if the perceptive faculty [= the memory] deals with matters learned [as well as with matters of observation and feeling] it will be the faculty for the processes of reason also: but these two orders certainly require two separate faculties.
Must we then suppose a common faculty of apprehension [one covering both sense perceptions and ideas] and assign memory in both orders to this?
The solution might serve if there were one and the same percipient for objects of sense and objects of the Intellectual-Kind; but if these stand in definite duality, then, for all we can say or do, we are left with two separate principles of memory; and, supposing each of the two orders of soul to possess both principles, then we have four.
