"His body plodded on mechanically, while his reasonable mind left him, and from without, looked down critically on him, wondering what that futile lumber did and why. Sometimes these selves would converse in the void; and then the madness was very near, as I believe it would be near the man who could see things through the veils at once of two customs, two educations, two environments."

-T.E. Lawrence (Lawrence of Arabia), "Seven Pillars of Wisdom"
