If we remember that this was the general attitude of mind, we cannot help asking how it could happen that in such a period and in such an atmosphere Maimonides arrived at the doctrine of the supremacy of reason in its most uncompromising form. No doubt, if we care to be satisfied with any answer that comes to hand, we may say that Maimonides, starting out with a predisposition in favour of the Arabic version of the Aristotelian philosophy, and a sternly logical mind, could not stop half-way, or fail to see the logical consequences of Aristotelianism. But when we observe how, with a devotion far greater than that of his non-Jewish teachers, he set himself to develop and extend the idea of the supremacy of reason till it became a complete, all-embracing theory of life; and when we remember also his love for the teachings of Judaism, which ought to have induced in him a disposition not to extend the empire of reason, but to restrict it: we are forced to confess that logic alone could never have produced this phenomenon. There must have been some psychological force, some inner motive power, to make Maimonides so extreme and uncompromising a champion of reason. We shall discover what this motive power was, I think, if we take account of the political position of the Jews at that time. It was a time when religious fanaticism was rife among the Moslems. In many countries to profess another religion meant death, and large numbers of Jews, who could with difficulty change their place of abode, accepted Mohammedanism, though but outwardly. One of these countries was Southern Spain, the birthplace of Maimonides, who was a boy of thirteen when religious persecution broke out in that country. It may or may not be true, as recent historians maintain, that he and his father and the whole family changed their religion under compulsion: the question has not yet been definitely settled. But there is no doubt that even if he was saved by some means from an open change of faith, he was at any rate forced to conceal his Judaism, for fear of oppression, so long as he lived in Spain and in Fez (where religious persecution first started, and fanaticism had its stronghold). It was only in Egypt that his troubles ceased, and when he reached Egypt he was already about thirty years of age. This, then, was the terrible position in which Maimonides spent his years of development. He was surrounded by lying and religious hypocrisy; Judaism had to hide from the light of day; its adherents had to wear a mask whenever they came out of their homes into the open. And why? Because Mohammed had called himself a prophet, had performed miracles, according to his followers, to win their faith, and by virtue of his prophetic power had promulgated a new Law and revealed new truths, which all men were bound to believe, although they were contrary to reason. This state of things was bound to make a profound impression
