Taken as a whole the ethical rules and commands of the Koran constitute an admirable code, one which has been an efficient force in the moral improvement and uplift of the peoples of vast regions of the earth. The morality inculcated has been succinctly characterized as a concrete and practical one. It is particularly well adapted to races in a low stage of culture. The very fact that, notwithstanding some serious defects and limitations, the code has been accepted by so large a part of the human race, and has, for over a thousand years, given moral guidance and inspiration to such vast multitudes, goes to prove that the great body of its rules and prescriptions of conduct are in general in line with the elemental laws of the moral world. III. THE MORAL LIFE [Sidenote: Mohammedan morality depressed by racial influences] In any comparison instituted between Christianity and Islam as moral regenerators of society there is need that the difference in the fields entered by these rival creeds be kept carefully in mind. Islam was placed at a disadvantage in that it went among the morally degenerate and dissolute peoples of the Orient, while Christianity had for its field the classical peoples and particularly the fresh German race. In those same Eastern lands and among those same Oriental or semi-Hellenized races Christianity had not only signally failed morally to reform and uplift society, but in that unfavorable environment had itself become lamentably degenerate and corrupt. In pointing out this disadvantage to which Islam has been subjected, a discerning Moslem writer says, “Like rivers flowing through varied tracts, both these creeds have produced results in accordance with the nature of the soil through which they have found their course.”[667] There is here the necessary recognition of the influence which the historical environment exercises upon the moral standard. The prerequisite of a good harvest in the field of morals, as in the physical world, is not only good seed but also a good soil. [Sidenote: Consequence of giving a religious sanction to war] The whole history of Islam, as already remarked, has been molded by the fact that fighting for the extension of the true religion was made by Mohammed a chief duty of the faithful. Islam’s wonderful career of conquest during the first century after its rise was in large measure the result of the Prophet having made war against infidels a pious duty. Hitherto war among the Arabs had been for the most part merely a raid or hunt. Now it was given an ethical-religious motive and thus made a crusade. In the space of a single century a large part of the countries which had formed the historic lands of antiquity had been brought by the Arabian warriors under the sway of Islam.
