“Thus the Utopia of terrestrial paradise implies an absolute humanity within the transitory relations of terrestrial history. But there is no room in terrestrial reality, by its nature strictly confined and limited, for an absolute life. Yet the Utopia theory asserts that what has been impossible until now will not be so always, that an absolute and conclusive state will sooner or later crown historical relations. It affirms, not a transition from limited historical relations to some other plane of being, to some fourth dimension commensurable with the closed three dimensional world, but a fourth dimension of absolute life within the very framework of three-dimensional space. In this lie its fundamental metaphysical antithesis and essential instability, instead of seeing absolute life as the transition from terrestrial to, celestial history, it presupposes an ultimate solution of human destiny within the framework of terrestrial relations, a final integration of the three-dimensional world. It desires to humanize that absolute perfection and beatitude which can only be attained in the celestial reality and only contained in the fourth dimension.” TimeParadiseMetaphysicsUtopia Book:The Meaning of History Source: The Meaning of History
