It is in the later and nominally decadent ages of the Bagdad Khalifate, when science and culture and even industry relatively prospered by reason of the personal impotence of the Khalifs, that we meet with the most pronounced and the most perspicacious of the Freethinkers of Islam. In the years 973-1057 there dwelt in the little Syrian town of Marratun-Numan the blind poet Abu'l-ala-al-Ma'arri, who wrote a parody of the Koran, [1096] and in his verse derided all religions as alike absurd, and yet was for some reason never persecuted. He has been pronounced "incomparably greater" than Omar Khayyám "both as a poet and as an agnostic." [1097] One of his sayings was that "The world holds two classes of men--intelligent men without religion, and religious men without intelligence." [1098] He may have escaped on the strength of a character for general eccentricity, for he was an ardent vegetarian and an opponent of all parentage, declaring that to bring a child into the world was to add to the sum of suffering. [1099] The fact that he was latterly a man of wealth, yet in person an ascetic and a generous giver, may be the true explanation. Whatever be the explanation of his immunity, the frankness of his heterodoxy is memorable. Nourished perhaps by a temper of protest set up in him by the blindness which fell upon him in childhood after smallpox, the spirit of reason seems to have been effectually developed in him by a stay of a year and a-half at Bagdad, where, in the days of Al Mansour, "Christians and Jews, Buddhists and Zoroastrians, Sabians and Sufis, materialists and rationalists," met and communed. [1100] Before his visit, his poems are substantially orthodox; later, their burden changes. He denies a resurrection, and is "wholly incredulous of any divine revelation. Religion, as he conceives it, is a product of the human mind, in which men believe through force of habit and education, never stopping to consider whether it is true." "His belief in God amounted, as it would seem, to little beyond a conviction that all things are governed by inexorable Fate." Concerning creeds he sings in one stave:-- Now this religion happens to prevail Until by that one it is overthrown; Because men will not live with men alone, But always with another fairy-tale [1101]-- a summing-up not to be improved upon here.
