by a child--or by a very futurist artist. Even a pyramid is like
a mathematical figure drawn by a schoolmaster teaching children;
and its very impressiveness is that of an ultimate Platonic abstraction.
There is something curiously simple about the shape in which
these colossal crystals of the ancient sands have been cast.
It is only when we have felt something of this element,
not only of simplicity, but of crudity, and even in a sense
of novelty, that we can begin to understand both the immensity
and the insufficiency of that power that came out of the desert,
the great religion of Mahomet.

In the red circle of the desert, in the dark and secret place,
the prophet discovers the obvious things. I do not say it
merely as a sneer, for obvious things are very easily forgotten;
and indeed every high civilisation decays by forgetting obvious things.
But it is true that in such a solitude men tend to take very simple
ideas as if they were entirely new ideas. There is a love of
concentration which comes from the lack of comparison. The lonely
man looking at the lonely palm-tree does see the elementary truths
about the palm-tree; and the elementary truths are very essential.
Thus he does see that though the palm-tree may be a very simple design,
it was not he who designed it. It may look like a tree drawn
by a child, but he is not the child who could draw it. He has not
command of that magic slate on which the pictures can come to life,
or of that magic green chalk of which the green lines can grow.
He sees at once that a power is at work in whose presence
he and the palm-tree are alike little children. In other words,
he is intelligent enough to believe in God; and the Moslem,
the man of the desert, is intelligent enough to believe in God.
But his belief is lacking in that humane complexity that comes
