Is not that your doctrine? What, then, becomes of the distinction between presentation and representation, between perception and imagination, if in both cases both a near and a remote object are or may be involved? You expressly state that the sole immediate object in perception is the organism; all that lies beyond is mediate. The organism is also the sole immediate object in imagination; all that lies beyond is mediate. How, then, can these two powers be discriminated as presentative (immediate) and representative (mediate)?
