The Memory of Coruscus

There are times when we do not know regarding such physical processes due to earlier sensations whether they are produced by sense experience. At another time it happens we think and recall that we have heard or known the thing in the past. This takes place when, after contemplating a thing in its own nature, when shifts one's position and regards it as the copy of another thing. Exercise in repeatedly recalling a thing strengthens the memory. But this is nothing more than the frequent contemplation of a thing as a copy, and not as an object in itself.
