Stout: Manual of Psychology (3rd edition), pp. 465-6. “We find that the definite apprehension of an order of coexistence, as such, arises and develops only in connection with that peculiar aspect of sense-experience which we have called extensity, and more especially the extensity of sight and touch. Two sounds or a sound and a smell may be presented as coexistent in the sense of being simultaneous; but taken by themselves apart from association with experiences of touch and sight, they are not apprehended as spatially juxtaposed or separated by a perceived spatial interval or as having perceived spatial direction and distance relatively to each other. Such relations can only be perceived or imagined, except perhaps in a very rudimentary way, when the external object is determined for us as an extensive whole by the extensity of the same presentation through which we apprehend it.”
