14. We need not wonder that the Easterns did not succeed in reaching an unadulterated conception of the Aristotelian philosophy. Our critical apparatus for discriminating between the genuine and the spurious was not in their possession. It must have proved even more difficult for them, to familiarize themselves with the world of Greek civilization, than for the Christian scholars of the Middle Ages, which had never entirely lost living touch with antiquity. In the East men remained dependent on Neo-Platonic redactions and interpretations. A part of the scientific system, to wit, the Politics of Aristotle, was a-wanting; and so, as a matter of course, the Laws or the Republic of Plato took its place. Only a few were aware of the difference between the two. Another determining motive deserves notice. In their Neo-Platonic sources even, the Muslims came upon a harmonizing exposition of the Greek philosophers, and they felt constrained to adopt it. The first adherents of Aristotle were bound to assume a polemical and apologetic attitude. In opposition to, or in conformity with, the voice of the Muslim community, they required a coherent philosophy, in which the One Truth must be found. The same reverence, which Mohammed in his day had paid to the sacred writings of the Jews and of the Christians, was shewn afterwards by Muslim scholars towards the works of Greek philosophers; but these learned men exhibited greater familiarity with their models, and less originality. In their eyes the old philosophers were invested with an authority, to which it was their duty to submit. The earliest Muslim thinkers were so fully convinced of the superiority of Greek knowledge that they did not doubt that it had attained to the highest degree of certainty. The thought of making farther and independent investigations did not readily occur to an Oriental, who cannot imagine a man without a teacher as being anything else than a disciple of Satan. In accordance, therefore, with the precedent set by Hellenistic philosophers, an attempt had to be made to demonstrate the existence of the harmony between Plato and Aristotle,—and, in particular, to shelve tacitly those doctrines which gave offence, or to exhibit them in a sense which was not too decidedly contrary to Muslim Dogmatics. In order to humour the opponents of Aristotle or of Philosophy in general, prominence was given to wise and edifying sayings out of the philosopher’s works,—both the genuine and the spurious,—that so the way might be prepared for the reception of his scientific thoughts. To the initiated, however, the teaching of Aristotle, like that of other schools and sects, was set forth as a higher truth, to which the positive faith of the multitude and the more or less firmly established system of the theologians were merely preliminary steps.
