The Turk and the Arab came out of big spaces, and they have the desire of them in their bones.

They settle down and stagnate, and by the by they degenerate into that appalling subtlety which is their ruling passion gone crooked.

And then comes a new revelation and a great simplifying.

They want to live face to face with God without a screen of ritual and images and priestcraft.

They want to prune life of its foolish fringes and get back to the noble bareness of the desert.
