It is true that the memory of the apple is only an image in the mind. However, we fail to notice that when we see the actual apple it is, in fact, also only an image. All we know of the apple, in that case, is seeing. And when we touch the apple, we only know touching; when we taste it we only know tasting; when we smell it we only know smelling.
We never experience the actual apple as it is conceived, that is, as an object in its own right with its own independent and separate existence.”
