pure perceptive mode of causal efficacy. The symbolic transference of course intensifies the definition. But, apart from such transference, there is some adequacy of definite demarcation.
Thus in the intersection of the two modes, the spatial and temporal relationships of the human body, as causally apprehended, to the external contemporary world, as immediately presented, afford a fairly definite scheme of spatial and temporal reference whereby we test the symbolic use of sense-projection for the determination of the positions of bodies controlling the course of nature. Ultimately all observation, scientific or popular, consists in the determination of the spatial relation of the bodily organs of the observer to the location of ‘projected’ sense-data.
7. The Contrast Between Accurate Definition and Importance.
The reason why the projected sense-data are in general used as symbol, is that they are handy, definite, and manageable. We can see, or not see, as we like: we can hear, or not hear. There are limits to this handiness of the sense-data: but they are emphatically the manageable elements in our perceptions of the world. The sense of control-
