Let us examine three points regarding the influence on Moslem morals and general conduct. In the first place stand the moral writings of ecclesiastical character. The morality is rooted in and based on the moral of the Bible and then on the developed Moslem law and has absorbed in itself some of the elements of the ethics of Christianity. In the second place, there is a series of ethical documents of a most valued nature in the shape of proverbs, dicta, maxims, fables, constituting a kind of moral philosophy, often independent of each other, varied in their character, and different as to time and the place of their compositions. Here we may separate a certain stratum of Persian element, and an analysis of them may reveal partly contemporary knowledge and partly elements of foreign religious ethics. The third but not the last place in importance is occupied by the Greek ethical tradition in which latterly are discernible important Christian constituents. Recent studies have yielded us as their result, this structure of Musalman ethics. But it is to be noted that the theoretical deductions at first sight do not find confirmation in facts. For we do not know which Greek books on ethics were translated in the beginning of the period of the scientific development of Islam, and for the support of our thesis we have to point to the possibility of oral transmission of Hellenic ethical tradition through Syriac scholars, although this circumstance does not militate against our hypothesis. Besides a small amount of translations from Greek ethical works, especially the books of Aristotle, there are observed among the works embodied in this tradition a series of pseudographs which, however, can have only an external relation with the Greek sciences and which would rather lead to the second group of the influences on Musalman ethical monuments namely, the group of monuments of "Oriental wisdom." The most typical of the pseudographical _wisaya_, or "Testaments" are ascribed to Aristotle, Pythagoras, and others. To our mind, they are derived from Persian tradition to the same extent, if not in a larger extent than from the Christian. Actual studies demonstrate that the basal work for this epoch was the book above-mentioned of Ibn Miskawaihi which as we saw above, issued from Persian literary tradition. And the character of that tradition can be explained from exterior circumstances without an analysis of its contents. The fact is that Ibn Miskawaihi worked upon that class of Persian material, for instance the _Pand Nameh_ or _Andarz_, which had nothing to do with the province of the indefinite gnomic literature but which had the character of a catechism and therefore expresses a definite system of religious morals, the morals of Parsism.[1] The appreciation of the influence of Parsism on Islam has only just commenced. But we are already in a position to emphasise the great influence, which Parsi ethics have exercised on Islam and this
