One of the chief «roots» of their discussions was how to reconcile the Divine justice and benevolence with the Divine prescience,--the predestination of some vessels to honour, and others to dishonour,--the pre-ordainment of all things by a kind of mechanical necessity (_Jabr_), leaving no possibility of the occurrence of any events except those which actually do occur. The consideration of one corollary of a similar doctrine moved the pious and gentle Cowper to use language of indignant dissent; and there is high theological authority for the view that it is calculated «to thrust some into desperation,» but to stimulate the piety of others. Omar is constantly dwelling on this doctrine, and he seems to be affected by it in the double way here mentioned. Other influences which acted on Omar must not be left out of account. Born as he was in Khorassan, «the focus of Persian culture,» he was no doubt familiar with speculations of the Moslem philosophers, Alkindi, Alfarabi, and Avicenna,[102] the last of whom he may possibly have seen. And though, think he was not himself a Sufi, in the sense of being affiliated to any Sufi order, he can hardly have been unaffected by the mysticism of which his predecessor in _Ruba'i_ writing, Abu Sa'id bin Abul Khair, his patron Nizam ul Mulk, and his distinguished countryman Imam Ghazali were all strong adherents. His philosophical studies would naturally stimulate his sceptical and irreligious dispositions, while his Mystic leanings would operate mainly in the contrary direction. If this explanation of the inconsistencies in his poetry be correct, it is obvious that the parallel often sought to be traced between him and Lucretius has no existence. Whatever he was, he was not an Atheist. To him, as to other Muhammadans of his time, to deny the existence of the Deity would seem to be tantamount to denying the existence of the world and of himself. And the conception of «laws of nature» was also one quite foreign to his habits of thought. As Deutsch says, «To a Shemite, Nature is simply what has been begotten, and is ruled absolutely by One Absolute Power.» Hammer compares him to Voltaire, but in reality he is a Voltaire and something more. He has much of Voltaire's flippancy and irreverence. His treatment of the doctrine of the Resurrection of the Body, for instance, which Muhammad took from Christianity, and travestied by the embellishments he added to it, is altogether in Voltaire's manner. And his insistence on the all importance of kindness and charity recalls the better side of Voltaire's character, viz., his kindness to Calas, and the other victims of ecclesiastical persecution. But Omar also possessed, what Voltaire did not, strong religious emotions, which at times overrode his rationalism, and found expression in those devotional and Mystical quatrains, which offer such a strong contrast to the rest of his poetry.
