Excerpt: The remarkable treatise, which I introduce to your notice, is a translation from one of the numerous works of the Arabian Philosopher, Abou Hamid Mohammed ben Mohammed al Ghazzali, who flourished in the eleventh century. He was born about the year A. D. 1056, or 450 of the Mohammedan era, at Tons in Khorasan, and he died in the prime of life in his native country about the year 1011, or 505 A. H. Although educated by Mohammedan parents, he avows that during a considerable period of his life he was a prey to doubts about the truth, and that at times he was an absolute sceptic. While yet comparatively young, his learning and genius recommended him to the renowned sovereign Nizam ul Mulk, who gave him a professorship in the college which he had founded at Bagdad. His speculative mind still harassing him with doubts, in his enthusiasm to arrive at a solid foundation for knowledge, he resigned his position, visited Mecca and Jerusalem, and finally returned to Khorasan, where he led a life of both monastic study and devotion, and consecrated his pen to writing the results of his meditations. Mohammedan scholars of the present day still hold him in such high respect, that his name is never mentioned by them without some such distinctive epithet, as the " Scientific Imaum," or "Chief witness for Islamism." His rank in the eastern world, as a philosopher and a theologian, had naturally given his name some distinction in our histories of philosophy, and it is enumerated in connection with those of Averroes (Abu Eoshd) and Avicenna (Abu Sina) as illustrating the intellectual life and the philosophical schools of the Mohammedans. Still his writings were less known than either of the two others. His principal work, The Destruction of the Philosophers, called forth in reply one of the two most important works of Averroes entitled The Destruction of the Destruction. Averroes, in his commentary upon Aristotle, extracts from Ghazzali copiously for the purpose of refuting his views. A short treatise of his had been published at Cologne, in 1506, and Pocock had given in Latin his interpretation of the two fundamental articles of the Mohammedan creed. Von Hammer printed in 1838, at Vienna, a translation of a moral essay, Eyuha el Weled, as a new year's token for youth. It has been reserved to our own times to obtain a more intimate acquaintance with Ghazzali, and this chiefly by means of a translation by M. Pallia, into French, of his Confessions, wherein he announces very clearly his philosophical views; and from an essay on his writings by M. Smölders. In consequence, Mr. Lewes, who in his first edition of the Biographical History of Philosophy, found no place for Ghazzali, is induced in his last edition, from the evidence which that treatise contains that he was one of the controlling minds of his age, to demote an entire section to an exhibition of his opinions in the same series with Abelard and Bruno, and to make him the typical figure to represent Arabian philosophy. For a full account of Ghazzali's school of philosophy, we refer to his history and to the two essays, just mentioned. We would observe, very briefly however, that like most of the learned Mohammedans of his age, he was a student of Aristotle. While they regarded all the Greek philosophers as infidels, they availed themselves of their logic and their principles of philosophy to maintain, as far possible, the dogmas of the Koran. Ghazzali's mind possessed however Platonizing tendencies, and he affiliated himself to the Soofies or Mystics in his later years. He was in antagonism with men who to him appeared, like Avicenna, to exalt reason above the Koran, yet he himself went to the extreme limits of reasoning in his endeavors to find an intelligible basis for the doctrines of the Koran, and a philosophical basis for a holy rule of life.
