I think you will recognize in Lawrence the personalities and cultural traits of the modern Arab:
This people was black and white, not only in vision, but by inmost furnishing: black and white not merely in clarity, but in apposition. Their thoughts were at ease only in extremes. They inhabited superlatives by choice. Sometimes inconsistents seemed to possess them at once in joint sway; but they never compromised: they pursued the logic of several incompatible opinions to absurd ends, without perceiving the incongruity. With cool head and tranquil judgement, imperturbably unconscious of the flight, they oscillated from asymptote to asymptote. *
Italics and typos mine.[* asymptote is from the Greek geometry term for lines that approach but never meet]

The Beduin could not look for God within him: he was too sure that he was within God. He could not conceive anything which was or was not God, Who alone was great; yet there was a homeliness, an everyday-ness of this climatic Arab God, who was their eating and their fighting and their lusting, the commonest of their thoughts, their familiar resource and companion, in a way impossible to those whose God is so wistfully veiled from them by despair of their carnal unworthiness of Him and by the decorum of formal worship. Arabs felt no incongruity in bringing God into the weaknesses and appetites of their least creditable causes. He was the most familiar of their words; and indeed we lost much eloquence when making Him the shortest and ugliest of our monosyllables.

Arabs could be swung on an idea as on a cord; for the unpledged allegiance of their minds made them obedient servants. ... Without a creed they could be taken to the four corners of the world (but not to heaven) by being shown the riches of earth and the pleasures of it; but if on the road, led in this fashion, they met the prophet of an idea, who had nowhere to lay his head and who depended for his food on charity or birds, then they would all leave their wealth for his inspiration. They were incorrigibly children of the idea, feckless and colour-blind, to whom body and spirit were for ever and inevitably opposed. Their mind was strange and dark, full of depressions and exaltations, lacking in rule, but with more of ardour and more fertile in belief than any other in the world. They were a people of starts, for whom the abstract was the strongest motive, the process of infinite courage and variety, and the end nothing.

...To most of them the word was never given; for those societies were pro-Arab only, willing to fight for nothing but Arab independence; and they could see no advantage in supporting the Allies rather than the Turks, since they did not believe our assurances that we would leave them free. Indeed, many of them preferred an Arabia united by Turkey in miserable subjection, to an Arabia divided up and slothful under the easier control of several European powers in spheres of influence.
