These principles are illustrated, perhaps, most clearly by the spread and modification of religious systems among peoples of different races. Take the case of the Moslem religion, which has gained acceptance among one-sixth of the population of the world in historic and in fact recent times, and is still spreading. The leading feature of this system is its acceptance of all that is and happens as being the will of God, the act of an entirely arbitrary, inscrutable, and absolutely powerful individual, before which men must simply bow without question or criticism; it is characterised by its simplicity and its fatalism. There seems good reason to believe that the tendency to unquestioning obedience to authority is a strong innate tendency of most Asiatics (except perhaps the Chinese and their relatives), far stronger than in most individuals of European peoples; for we see it expressed in many ways in their institutions and history, both of those who are and those who are not Moslems[56]; and Asiatic fatalism has, in fact, become proverbial. With the causes or origin of this innate quality we are not now concerned; but, accepting it as a fact, we may note that it is among Asiatics that Mohammedanism has secured the great mass of its converts; and that in India, in spite of many minor features that are opposed to the spirit of Hindooism, it continues to spread largely; while Christianity makes but little progress. Buddhism on the other hand has almost faded away, after an initial success in the country of its origin, but has continued to gain adherents and has become the dominant religion among the yellow peoples further east, in Burma, China, Thibet, Japan. The Moslem religion, having been thus accepted in virtue of the fact that its dominant tendency is in harmony with the strong innate tendency to unquestioning submission to a supreme will, then accentuates this tendency in all its converts, moulding their political relations to the same type, so that all recognise one earthly regent of God; and it has led to the almost complete suppression of any spark of the spirit of inquiry and scepticism that might otherwise display itself among these peoples.
