THE PERCEPTION OF SPACE. 151 



Tlius it appears indubitable that all space-relations ex- 

 cept those of magnitude are nothing more or less than pure 

 sensational objects. But magnitude appears to outstep this 

 narrow sphere. We have relations of muchness and little- 

 ness between times, numbers, intensities, and qualities, as 

 well as spaces. It is impossible, then, that such relations 

 should form a particular kind of simply spatial feeling. 

 This we must admit : the relation of quantity is generic 

 and occurs in many categories of consciousness, whilst the 

 other relations we have considered are specific and occur 

 in space alone. When our attention passes from a shorter 

 line to a longer, from a smaller spot to a larger, from a 

 feebler light to a stronger, from a paler blue to a richer, 

 from a march tune to a galop, the transition is accompanied 

 in the synthetic field of consciousness by a peculiar feeling 

 of difference which is what we call the sensation of onore, — 

 more length, more expanse, more light, more blue, more 

 motion. This transitional sensation of more must be iden- 

 tical with itself under all these different accompaniments, 

 or we should not give it the same name in every case. We 

 get it when we pass from a short vertical line to a long 

 horizontal one, from a small square to a large circle, as 

 well as when we pass between those figures whose shapes 

 are congruous. But when the shajDes are congruous our 

 consciousness of the relation is a good deal more distinct, 

 and it is most distinct of all when, in the exercise of our 

 analytic attention, we notice, first, a part, and then the 

 tvhole, of a single line or shape. Then the more of the whole 

 actually sticks out, as a separate piece of space, and is so 

 envisaged. The same exact sensation of it is given when 

 we are able to superpose one line or figure on another. This 

 indispensable condition of exact measurement of the more 

 has led some to think that the feeling itself arose in every 

 case from original experiences of superposition. This is 



"through the relation to right and left, which is a matter of immediate 

 intuition." In these last words {welches unmittelbar anf Anschauung geht 

 — Prolegomena, § 12) Kant expresses all that we have meant by speaking 

 of up and down, right and left, as sensations. He is wrong, however, in 

 invoking relation to extrinsic total space as essential to the existence of 

 these contrasts in figures. Relation lo our own body is enough.
