A question which we have left unanswered is that of origins. The reader will find that in trimming the ramifications of historical beginnings we have exposed the trunks rather than the roots of Egyptian and Mesopotamian civilization. To what extent can their roots be known; what were the forces that brought them into being? I think that the historian must deem this question unanswerable. It can but lead him astray in the direction of quasi-philosophical speculations, or tempt him to give pseudo-scientific answers. It is the latter alternative which has done most harm, for time and again such changes as an increase in food-production or technological advances (both, truly enough, coincidental with the rise of civilization) have been supposed to explain how civilization became possible. This misconception bars the road to a deeper understanding. For Whitehead’s words are valid for past and present alike:

In each age of the world distinguished by high activity there will be found at its culmination, and among the agencies leading to that culmination, some profound cosmological outlook, implicitly accepted, impressing its own type upon the current springs of action. This ultimate cosmology is only partly expressed, and the details of such expression issue into derivative specialized questions ... which conceal a general agreement upon first principles almost too obvious to need expression, and almost too general to be capable of expression. In each period there is a general form of the forms of thought; and, like the air we breathe, such a form is so translucent, and so pervading, and so seemingly necessary, that only by extreme effort can we become aware of it.[1]

It is this effort which the historian cannot shirk, nor is there a short cut to the understanding of an alien past; but I believe that the comparative study of parallel phenomena leads most surely to an elucidation of manifest and implicit form.

I have confined myself to Egypt and Mesopotamia, the cultural centres of the Ancient Near East; for in the peripheral regions civilization arose late and was always, to some extent, derivative. Egypt, too, was influenced by Mesopotamia during its formative period, but without losing its distinct and highly individual character. This matter of early cultural contact is of such importance for our problem that I have discussed the relevant evidence in an Appendix.
