There are three axes
to which the colours red,
yellow, and white are
assigned, the faces of
each cube are designated
by taking these colours in pairs. Taking all the colours
together we get a colour name for the solidity of a cube.
Let us now ask ourselves how the cube would be presented
to the plane being. Without going into the question
of how he could have a real experience of it, let us see
how, if we could turn it about and show it to him, he,
under his limitations, could get information about it.
If the cube were placed with its red and yellow axes
against a plane, that is resting against it by its orange

by red and yellow lines, and having null points. See the
dotted square, fig. 87.
We could turn the cube about the red line so that a
different face comes into juxtaposition with the plane.
Suppose the cube turned about the red line. As it
is turning from its first position all of it except the red
