We may say of the Arabians that their philosophy constitutes no characteristic stage in the development of philosophy. The principal points in this, as in the later philosophy, were the question whether the world is eternal, and the task of proving the unity of God and similar dogmas. One great consideration in all this, however, was to defend the doctrines of Mohammedanism, and owing to this all philosophizing had to be carried on within the limits of these doctrines. The Arabians, like the Christians of the West, were restricted by the dogmas of their Church (if one may call it so), few though these dogmas were; yet this last circumstance of the small number of the dogmas certainly gave them greater liberty. But according to all that we know of them, they established no principle of self-conscious reason that was truly higher, and thus they brought Philosophy no further. They have no other principle than that of revelation, therefore only a principle that is external. A. PHILOSOPHY OF THE MEDABBERIM. The Medabberim are specially mentioned by Moses Maimonides as a widely extended philosophic school or sect of considerable eminence. He speaks (More Nevochim, P. I. c. 71, pp. 134, 135) of the peculiarity of their method of philosophy somewhat as follows: “The Ishmaelites, however, have extended their discourses still further, and have aspired to other wonderful doctrines, of which none of the Greek Medabberim knew anything, because they were still on some points in agreement with the philosophers. The main point to be remarked is that all the Medabberim, whether among the Greeks who had become Christians, or among the Ishmaelites, in the building up of their principles did not follow the nature of the matter itself, or draw their arguments from it, but only had in view how the subject must be regarded in order to support their assertion, or at least not to refute it altogether: afterwards they boldly asserted that these were the circumstances of the case, and adduced further arguments and maxims in support of their object. They insisted on that, and that alone, which concurred with their opinions, even though it were in the most remote degree, through a hundred links of reasoning. The earliest of their learned men adopted this practice, though professing that they reached these reflections through speculation alone, without reference to any preconceived opinion. Their successors did not follow their example,” &c.
