In the course of our further conversation it came out that, as a consequence of foresight, some of the commonest emotions of human nature are unknown on Mars. They for whom the future has no mystery can, of course, know neither hope nor fear. Moreover, every one being assured what he shall attain to and what not, there can be no such thing as rivalship, or emulation, or any sort of competition in any respect; and therefore all the brood of heart-burnings and hatreds, engendered on Earth by the strife of man with man, is unknown to the people of Mars, save from the study of our planet. When I asked if there were not, after all, a lack of spontaneity, of sense of freedom, in leading lives fixed in all details beforehand, I was reminded that there was no difference in that respect between the lives of the people of Earth and of Mars, both alike being according to God’s will in every particular. We knew that will only after the event, they before,--that was all. For the rest, God moved them through their wills as He did us, so that they had no more dense of compulsion in what they did than we on Earth have in carrying out an anticipated line of action, in cases where our anticipations chance to be correct. Of the absorbing interest which the study of the plan of their future lives possessed for the people of Mars, my companion spoke eloquently. It was, he said, like the fascination to a mathematician of a most elaborate and exquisite demonstration, a perfect algebraical equation, with the glowing realities of life in place of figures and symbols. When I asked if it never occurred to them to wish their futures different, he replied that such a question could only have been asked by one from the Earth. No one could have foresight, or clearly believe that God had it, without realizing that the future is as incapable of being changed as the past. And not only this, but to foresee events was to foresee their logical necessity so clearly that to desire them different was as impossible as seriously to wish that two and two made five instead of four. No person could ever thoughtfully wish anything different, for so closely are all things, the small with the great, woven together by God that to draw out the smallest thread would unravel creation through all eternity.
