Steam had always taken it for granted that the dichotomy of belief and behavior was the cornerstone of the Mosley world. It was too deep to be called hypocrisy; it was merely custom. They said one thing and they did something else. They affirmed their adherence to Islam in formulated phrases, but they behaved as though they believed, and actually did believe, something quite different. Still, the unchanging profession of faith was there, and to him, it was this eternal contradiction which made them Muslims. But Amar’s relationship to his religion was far more robust: he believed it's possible to practice literally what the Koran enjoined him to profess. He kept the precepts constantly in his hand, and applied them on every occasion, at every moment. The fact that such a person as Amar could be produced by this society rather upset Steam’s calculations. For Steam, the exception invalidated the rule instead of proving it: if there were one Amar, there could be others. Then the Moroccans were not the known quantity he had thought they were, inexorably conditioned by the pressure of their own rigid society; his entire construction was false in consequence, because it was too simple and did not make allowances for individual variations.
