CHAPTER I A.D. 600—The Middle East in Disintegration THE POSITION that the Middle East occupies in history is a unique one. It was there in all probability that Man, having lived for perhaps one million years in complete dependence on the wild vegetable and animal foods that he could acquire by gathering and hunting, learnt by laborious trial and error some 8,000 or so years ago to cultivate food-plants and to domesticate certain useful animals, and so for the first time became capable of advancing to a higher civilization. From between three and two thousand years ago, as the map of that higher civilization in the Middle East was beginning to burn lower, there sprang from it two beams of dazzling light, the moral-intellectual beam of Greek humanistic thought and the moral-spiritual beam of the Judaeo-Christian awareness of God's Presence, which have con- jointly illuminated Western civilization down to the present time. There have been periods in which one of these twin lights has shone more brightly than the other; but without the two of them our own civilization could not have come into existence; and where either of them is extinguished, as some men have thought to extinguish them in the last thirty years, our witness is that the very tissue of civilization degenerates by rapid and dreadful processes into a malignant and swelling growth of barbarism. Man's great step forward from food-gathering to agriculture, his Response to a great Challenge1 presented by fundamental changes in his natural environment, has been well set forth by archaeologists in the last thirty years. So many learned and bril- liant books have been written about the Greek genius, aad about the origins and growth of our Christian Faith, that one would be perplexed where to advise the enquiring reader to turn first for enlightenment on these subjects. On the Silver Age of the Middle East also, the age of the Islamic or so-called Arab Civilization, 1 cf. A. J. Toynbee, A Study of History, one vol. abridgement, part II, especially 68 if.
