To the Martian the opinion held by these individuals presented two difficulties. First, if the adherents of this hypothesis considered their deity as a providence which took an active part in the life of this world, then the objections heretofore stated against belief in a personal god are still valid. Secondly, if they considered this being as only a creator, who then leaves this world to its own resources, they are only assuming a philosophical existence behind phenomena. Such a being, they believe, they deduce intellectually. But actually who created this creator? They assume a god who remains always hidden behind phenomena, but such a god has no connection with the God that the religious man worships and to whom he prays for guidance and for blessings, for actual interference in the life of this world. Such theories impress our visitor as but a feeble attempt at new concepts of the same hypothetical deity, and it seemed to him that we already had sufficient ideas of God to trouble our earthly minds. (3) The god of the Physicists. It was brought to the Martian's attention that two scientists, Sir Arthur Eddington, a British astronomer, and Sir James Jeans, a mathematical physicist, had still another concept of God. According to Eddington, "Phenomena all boil down to a scheme of symbols, of mathematical equations." He admits that this mathematics of nature does not explain anything. They do not define reality, they only define the relations that exist between the phenomena of reality. So far does he go, and then his limited mind, our Martian perceives, meets an obstacle that he cannot explain. He, therefore, abandons the formula and returns to the human mind which has conceived this formula. From the "spiritual essence of Man's nature," he assumes the spiritual nature of the cosmos itself, which he finds in what religion has known for centuries as God. To him, it is impossible to explain the universe except in terms of spirit. Professor Jeans insists that in the equations which reveal the relations between phenomena, there may reside also the revelation of the ultimate which these phenomena express. He believes that there may exist "a great architect of the universe who is a pure mathematician." However, the Martian argues, "Is it not a fact that in your earthly experience, you have created your gods in your own image? Your savages created God in the only fashion their mental capacities could supply, in the shape of an idol; now the modern physicist creates his god in the light of his own intimate vision, which is that of a mathematician! This is just another attempt to formulate an hypothetical existence of a supernatural being."
