The other question concerns the fundamental problem of European medievalism. We see that the problems with which the middle ages in Europe were confronted and also that European ethics and metaphysics were identical with the Muhammedan system: we are moreover assured that the acceptance of Christian ideas by Islam can only have taken place in the East: and the conclusion is obvious that mediaeval Christianity was also primarily rooted in the East. The transmission of this religious philosophy to the non-Oriental peoples of the West at first produced a cessation of progress but opened a new intellectual world when these peoples awoke to life in the thirteenth and fourteenth centuries. But throughout the intermediate period between the seventh and thirteenth centuries the East was gaining political strength and was naturally superior to the West where political organisation and culture had been shattered by the Germanic invasions; in the East again there was an organic unity of national strength and intellectual ideals, as the course of development had not been interrupted. Though special dogmatic points had been changed, the general religious theory remained unaltered throughout the nearer East. Thus the rising power of Islam, which had high faculties of self-accommodation to environment, was able to enter upon the heritage of the mixed Graeco-Oriental civilisation existing in the East; in consequence it gained an immediate advantage over the West, where Eastern ideas were acclimatised with difficulty.
