10. The most valuable portion of the legacy which the Greek mind bequeathed to us in art, poetry, and historical composition, was never accessible to the Orientals. It would even have been difficult for them to understand it, seeing that they lacked the due acquaintance with Greek life, and the relish for it. For them the history of Greece began with Alexander the Great, surrounded with the halo of legend; and the position which Aristotle held beside the greatest prince of ancient times must have assuredly conduced to the acceptance of the Aristotelian philosophy at the Muslim court. Arab historians counted up the Greek princes, on to Cleopatra, and then the Roman Emperors; but a Thucydides, for example, was not known to them, even by name. Of Homer they had not picked up much more than the sentence, that “one only should be the ruler”. They had not the least idea of the great Greek dramatists and lyric poets. It was only through its Mathematics, Natural Science and Philosophy, that Greek antiquity could bring its influence to bear upon them. They had come to know something of the development of Greek Philosophy, from Plutarch, Porphyry and others, as well as from the writings of Aristotle and Galen. A good deal of legendary matter, however, was mingled with their information; and the account which passed in the East, of the doctrines of the Pre-Socratic philosophers can only be referred by us to the pseudepigraphs which they consulted, or perhaps even to the opinions which had been developed in the East itself, and which they endeavoured to support with the authority of old Greek sages. But still, in every case, our thoughts must turn first of all to some Greek original. 11. It may be affirmed generally that the Syro-Arabs took up the thread of philosophy, precisely where the last of the Greeks had let it fall, that is, with the Neo-Platonic explanation of Aristotle, along with whose philosophy the works of Plato were also read and expounded. Among the Harranaeans, and for a long time in several Muslim sects, it was Platonic or Pythagorean-Platonic studies which were prosecuted with most ardour,—with which much that was Stoic or Neo-Platonic was associated. Extraordinary interest was taken in the fate of Socrates, who had suffered a martyr’s death in heathen Athens for his rational belief. The Platonic teaching regarding the Soul and Nature exercised great influence. The Pythian utterance: “Know thyself”,—handed down as the motto of the Socratic wisdom, and interpreted in a Neo-Platonic sense,—was ascribed by the Muslims to Ali, Mohammed’s son-in-law, or even put into the mouth of the Prophet himself. “He who knows himself, knows God his Lord thereby”: this was the text for Mystic speculations of all kinds.
