In no respect has the theory been more grossly exaggerated and misrepresented than in its application to religion. True philosopher that he was, Marx realized the absurdity of attempting "to abstract religious sentiment from the course of history, to place it by itself."[70] He recognized that all religion is, fundamentally, man's effort to put himself into harmonious relation with, and to discover an interpretation of, the forces of the universe. The more incomprehensible those forces, the greater man's need of an explanation of them. He could not fail to see that the religion of a people always bears a marked relation to their mental development and their special environment. He knew that at various stages the Yahve of the Hebrews represented very different conceptions, answering to changes in the social and political conditions of the people. To the primitive Israelitish tribes, Yahve was, as Professor Rauschenbusch remarks,[71] a tribal god, fortunately stronger than the gods of the neighboring tribes, but not fundamentally different from them, and the way to win his favor was to sacrifice abundantly. Later, with the development of a national spirit, the religious ideal became a theocracy, and Yahve became a King and Supreme Lord. In times of oppression and war Yahve was a God of War, but under other conditions he was a God of Peace. At every step the conception of Yahve bears a very definite relation to the material life.[72] Marx knew that primitive religions have often a celestial pantheon fashioned after the existing social order, kings being gods, aristocrats being demigods, and common mortals occupying a celestial rank equal to their terrestrial one. The celestial hierarchy of the Chinese, for example, is an exact reproduction of the earthly hierarchy, and all the privileges of rank are observed celestially as on earth. So in India we find the religions reproducing in their concepts of heaven the degrees and divisions of the various castes,[73] while our own American Indian conceived of a celestial hunting ground, with abundant reward of game, as his Paradise. "The religious world is but the reflex of the real world," said Marx,[74] and the phrase has been used, both by disciples and critics, as an attack upon religion itself; as showing that the Marxian philosophy excludes the possibility of religious belief. Obviously, however, the passage will not bear such an interpretation. To say that "the religious world is but the reflex of the real world" is by no means to deny that men have been benefited by seeking an interpretation of the forces of the universe, or to assert that the quest for such an interpretation is incompatible with rational conduct. In his scorn for Bakunin's "Alliance" programme with its dogmatic atheism[75] Marx was perfectly consistent. The passage quoted simply lays down, in bare outline, a principle which, if well founded, enables us to study comparative religion from a new viewpoint.
