He thinks that the relation between the body and the soul is determined by the soul. And seeing that in this way the circumstances and sufferings of the soul admit of being discerned by means of the physiognomy, the medical man has to be at the same time a physician of the soul. Therefore he drew up a system of spiritual medicine,—a kind of Dietetic of the Soul. The precepts of Muslim law, like the prohibition of wine, and so on, gave him no concern, but his freethinking seems to have led him into pessimism. In fact he found more evil than good in the world, and described inclination as the absence of disinclination.
High though the value was which Razi put upon Aristotle and Galen, he did not give himself any special trouble to gain a more profound comprehension of their works. He was a devoted student of Alchemy, which in his view was a true art, based on the existence of a primeval matter,—an art indispensable to philosophers, and which, he believed, had been practised by Pythagoras, Democritus, Plato, Aristotle and Galen. In opposition to Peripatetic teaching he assumed that the body contained in itself the principle of movement, a thought which might certainly have proved a fruitful one in Natural Science, if it had been recognized and farther developed.
Razi’s Metaphysic starts from old doctrines, which his contemporaries ascribed to Anaxagoras, Empedocles, Mani and others. At the apex of his system stand five co-eternal [[79]]principles,—the Creator, the Universal Soul, the First or Primeval matter, Absolute Space, and Absolute Time or Eternal Duration. In these the necessary conditions of the actually existing world are given. The individual sense-perceptions, generally, presuppose an existing Matter, just as the grouping of different perceived objects postulates Space. Perceptions of change farther constrain us to assume the condition of Time. The existence of living beings leads us to recognize a Soul; and the fact that some of these living beings are endowed with Reason, i.e.—have the faculty of bringing the Arts to the highest perfection,—necessitates our belief in a wise Creator, whose Reason has ordered everything for the best.
Notwithstanding the eternity of his five principles, Razi thus speaks of a Creator and even gives a story of Creation. First then a simple, pure, spiritual Light was created, the material of Souls, which are simple, spiritual substances, of the nature of Light. That Light-material or Upper-world, from which souls descended, is also called Reason, or Light of the Light of God. The Light is followed by the Shadow, from which the Animal Soul is created, for the service of the Rational Soul. But simultaneously with the simple, spiritual light, there existed from the first a composite form, which is Body, from the shadow of which now issue the four “natures”, Warmth and Cold, Dryness and Moistness. From these four natures at last are formed all heavenly and earthly bodies. The whole process, however, is in operation from all eternity, without beginning in time, for God was never inactive.
That Razi was an astrologer is plain from his own utterances. The heavenly bodies consist indeed, according [[80]]to him, of the same elements as earthly things, and the latter are continually exposed to the influences of the former.
6. Razi had to maintain a polemical attitude in two directions. On the one side he impugned the Muslim Unity of God, which could not bear to be associated with any eternal soul, matter, space or time; and on the other side he attacked the Dahrite system, which does not acknowledge any Creator of the world. This system, which is frequently mentioned by Muslim authors, with due aversion of course, appears to have found numerous representatives, though none of any importance. The adherents of the ‘Dahr’ (v. [I, 2, § 2]) are represented to us as Materialists, Sensualists, Atheists, Believers in the transmigration of souls, and so on; but we learn nothing more definite about their doctrines. In any case the Dahrites had no need to trace all that exists to a principle which was of spiritual essence and creative efficiency. Muslim Philosophy, on the other hand, did stand in need of such a principle, if it should only conform in some degree to the teaching of the faith. Natural Philosophy was not suited for the furtherance of this object, as it showed more interest in the manifold and often contrary operations of Nature than in the One Cause of all. Such aim was better attained by Neo-Platonic Aristotelianism, whose logico-metaphysical speculations endeavoured to trace all existence to one highest existence, or to derive all things from one supreme operative principle. But before we attend to this direction of thought, which commenced to appear even in the ninth century, we have still to give some account of an attempt to blend Natural Philosophy and the teachings of the Faith into a Philosophy of Religion.

2. The Faithful Brethren of Basra.
1. In the East, where every religion formed a State within the State, a political party invariably made its appearance in the additional character of a religious sect, just to gain adherents in some way or other. As a matter of principle indeed, Islam knew no distinction between men,—no caste or social standing. But property and education have the same influence everywhere; and in their train degrees of piety and stages of knowledge began to be set up, according as a community or party permitted of adjustment. Thus there arose secret societies having different grades, of which the highest and perhaps the next highest possessed an esoteric doctrine, which borrowed a good deal from the Natural Philosophy of the Neo-Pythagoreans. In furtherance of their object, which was to conquer political power, every expedient was regarded as lawful. For the initiated the Koran was explained allegorically. They traced their mystic lore, it is true, back to prophets with Biblical and Koranic names, but heathen philosophers were at the bottom of it all. Philosophy was completely transformed into a mythology of politics. The high intelligences and souls, which theoretic thinkers had recognized in the stars and planets, embodied themselves in human beings for the work of actual Politics; and it was declared to be a religious duty to assist these embodied intelligences in the establishment of an earthly kingdom of righteousness. The associations which acted in this way may best be compared to societies, which up to the days of Saint-Simonism and kindred phenomena in last century were wont to appear in countries where freedom of thought was restricted.

In the second half of the ninth century Abdallah ibn Maimun, head of the Karmatite party, was the originator of a movement of this kind. He was a Persian oculist, trained in the school of the Natural Philosophers. He proved able to associate both believers and freethinkers in a confederacy to endeavour to compass the overthrow of the Abbasid government. To the one set he was a conjurer, to the other a pious ascetic or learned philosopher. His colours were white, because his religion was that of the pure light, to which the soul was to ascend after its earthly wanderings. The duties inculcated were contempt for the body, disregard of the Material, community of goods for all the confederate brethren, as well as self-surrender to the confederacy, and fidelity and obedience to their chiefs, even to death,—for the society had its grades. In accordance with the sequence of existence, viz., God, Reason, Soul, Space and Time, they conceived the revelation of God to be made in history and in the constitution of their own brotherhood.
