THE NEO-PLATONIC ARISTOTELIANS OF PERSIA.
With the Arab conquest of Persia, a new era begins in the history of Persian thought. But the warlike sons of sandy Arabia whose swords terminated, at Nahāwand, the political independence of this ancient people, could hardly touch the intellectual freedom of the converted Zoroastrian.
The political revolution brought about by the Arab conquest marks the beginning of interaction between the Aryan and the Semitic, and we find that the Persian, though he lets the surface of his life become largely semitised, quietly converts Islām to his own Aryan habits of thought. In the west the sober Hellenic intellect interpreted another Semitic religion—Christianity; and the results of interpretation in both cases are strikingly similar. In each case the aim of the interpreting intellect is to soften the extreme rigidity of an absolute law imposed on the individual from without; in one word it is an endeavour to internalise the external. This process of transformation began with the study of Greek thought which, though combined with other causes, hindered the growth of native speculation, yet marked a transition from the purely objective attitude of Pre-Islamic Persian Philosophy to the subjective attitude of later thinkers. It is, I believe, largely due to the influence of foreign thought that the old monistic tendency when it reasserted itself about the end of the 8th century, assumed a much more spiritual aspect; and, in its later development, revivified and spiritualised the old Iranian dualism of Light and Darkness. The fact, therefore, that Greek thought roused into fresh life the subtle Persian intellect, and largely contributed to, and was finally assimilated by the general course of intellectual evolution in Persia, justifies us in briefly running over, even though at the risk of repetition, the systems of the Persian Neo-Platonists who, as such, deserve very little attention in a history of purely Persian thought.
It must, however, be remembered that Greek wisdom flowed towards the Moslem east through Ḥarrān and Syria. The Syrians took up the latest Greek speculation i.e. Neo-Platonism and transmitted to the Moslem what they believed to be the real philosophy of Aristotle. It is surprising that Mohammedan Philosophers, Arabs as well as Persians, continued wrangling over what they believed to be the real teaching of Aristotle and Plato, and it never occurred to them that for a thorough comprehension of their Philosophies, the knowledge of Greek language was absolutely necessary. So great was their ignorance that an epitomised translation of the Enneads of Plotinus was accepted as "Theology of Aristotle". It took them centuries to arrive at a clear conception of the two great masters of Greek thought; and it is doubtful whether they ever completely understood them. Avicenna is certainly clearer and more original than Al-Fārābī and Ibn Maskawaih; and the Andelusian Averroes, though he is nearer to Aristotle than any of his predecessors, is yet far from a complete grasp of Aristotle's Philosophy. It would, however, be unjust to accuse them of servile imitation. The history of their speculation is one continuous attempt to wade through a hopeless mass of absurdities that careless translators of Greek Philosophy had introduced. They had largely to rethink the Philosophies of Aristotle and Plato. Their commentaries constitute, so to speak, an effort at discovery, not exposition. The very circumstances which left them no time to think out independent systems of thought, point to a subtle mind, unfortunately cabined and cribbed by a heap of obstructing nonsense that patient industry had gradually to eliminate, and thus to winnow out truth from falsehood. With these preliminary remarks we proceed to consider Persian students of Greek Philosophy individually.
