X. But by far the most important question we have to face is that of the nature and extent of the influence exercised by what we call Eastern wisdom on the Greek mind. It is a common idea even now that the Greeks in some way derived their philosophy from Egypt and Babylon, and we must therefore try to understand as clearly as possible what such a statement really means. To begin with, we must observe that no writer of the period during which Greek philosophy flourished knows anything at all of its having come from the East. Herodotos would not have omitted to say so, had he ever heard of it; for it would have confirmed his own belief in the Egyptian origin of Greek religion and civilisation.[20] Plato, who had a very great respect for the Egyptians on other grounds, distinctly implies that they were a businesslike rather than a philosophical people.[21] Aristotle speaks only of the origin of mathematics in Egypt[22] (a point to which we shall return), though, if he had known of an Egyptian philosophy, it would have suited his argument better to mention that. It is not till a far later date, when Egyptian priests and Alexandrian Jews began to vie with one another in discovering the sources of Greek philosophy in their own past, that we first have definite statements to the effect that it came from Phoenicia or Egypt. Here, however, we must carefully note two things. In the first place, the word “philosophy” had come by that time to include theology of a more or less mystical type, and was even applied to various forms of asceticism.[23] In the second place, the so-called Egyptian philosophy was only arrived at by a process of turning primitive myths into allegories. We are still able to judge Philo’s Old Testament interpretation for ourselves, and we may be sure that the Egyptian allegorists were even more arbitrary; for they had far less promising material to work on. Nothing can be more savage than the myth of Isis and Osiris;[24] yet it is first interpreted according to the ideas of later Greek philosophy, and then declared to be the original source of that philosophy. Footnote 20: All he can say is that the worship of Dionysos and the doctrine of transmigration came from Egypt (ii. 49, 123). We shall see that both these statements are incorrect, and in any case they do not imply anything directly as to philosophy. Footnote 21: In _Rep._ 435 e, after saying that τὸ θυμοειδές is characteristic of the Thracians and Scythians, and τὸ φιλομαθές of the Hellenes, he refers us to Phoenicia and Egypt for τὸ φιλοχρήματον. In the _Laws_, where the Egyptians are so strongly commended for their conservatism in matters of art, he says (747 b 6) that arithmetical studies are valuable only if we remove all ἀνελευθερία and φιλοχρηματία from the souls of the learners. Otherwise, we produce πανουργία instead of σοφία, as we can see that the Phoenicians, the Egyptians, and many other peoples do. Footnote 22:
