I have spoken just above of the shape of the touch object for which our visual experiences stand as signs.

What do we mean by its shape?
To the plain man real things are the touch things of which he has experience, and these touch things are very clearly distinguishable from one another in shape, in size, in position, nor are the different parts| of the things to be confounded with each other.

Suppose that, as we pass our hand over a table, all the sensations of touch and movement which we experience fused into an undistinguishable mass.

Would we have any notion of size or shape?
It is because our experiences of touch and movement do not fuse, but remain distinguishable from each other, and we are conscious of them as _arranged_, as constituting a system, that we can distinguish between this part of a thing and that, this thing and that.
This arrangement, this order, of what is revealed by touch and movement, we may call the "form" of the touch world.

Leaving out of consideration, for the present, time relations, we may say that the "form" of the touch world is the whole system of actual and possible relations of arrangement between the elements which make it up.
