Of course no one nowadays would rest the case for the Oriental origin of Greek philosophy on the evidence of Clement or Eusebios; the favourite argument in recent times has been the analogy of the arts and religion. We are seeing more and more, it is said, that the Greeks derived their art and many of their religious ideas from the East; and it is urged that the same will in all probability prove true of their philosophy. This is a specious argument, but not in the least conclusive. It ignores altogether the essential difference in the way these things are transmitted from people to people. Material civilisation and the arts may pass easily from one people to another, though they have not a common language, and certain simple religious ideas can be conveyed by ritual better than in any other way. Philosophy, on the other hand, can only be expressed in abstract language, and it can only be transmitted by educated men, whether by means of books or oral teaching. Now we know of no Greek, in the times we are dealing with, who knew enough of any Oriental language to read an Egyptian book or even to listen to the discourse of an Egyptian priest, and we never hear till a late date of Oriental teachers who wrote or spoke in Greek. The Greek traveller in Egypt would no doubt pick up a few words of Egyptian, and it is certain that somehow or other the priests could make themselves understood by the Greeks. They were able to rebuke Hekataios for his family pride, and Plato tells a story of the same sort at the beginning of the _Timaeus_.[28] But they must have made use of interpreters, and it is impossible to conceive of philosophical ideas being communicated through an uneducated dragoman.[29] Footnote 28: Herod. ii. 143; Plato, _Tim._ 22 b 3. Footnote 29: Gomperz’s “native bride,” who discusses the wisdom of her people with her Greek lord (_Greek Thinkers_, vol. i. p. 95), does not convince me either. She would probably teach her maids the rites of strange goddesses; but she would not be likely to talk theology with her husband, and still less philosophy or science. The use of Babylonian as an international language will account for the fact that the Egyptians knew something of Babylonian astronomy; but it does not help us to explain how the Greeks could communicate with the Egyptians. It is plain that the Greeks did not even know of this international language; for it is just the sort of thing they would have recorded with interest if they had. In early days, they may have met with it in Cyprus, but that was apparently forgotten.
