ABSTRACT Besides geographical boundlessness, the claim to totality that characterizes universal histories comprises a temporal horizon, which reaches from the Creation to the end of the world predestined to Christians. The article examines the role of religious approaches on the one hand and secular points of view on the other in the transformation of eschatology into the idea of an open future shapeable by humans. The analysis focusses first on works by Johann Gottfried Herder (1744–1803). While the above-mentioned transformation is usually interpreted as a process of secularization, this article reveals a reliance on religious hopes for the afterlife, also and especially where progressistic expectations for the development of the individual as well as of humanity were articulated. A second step leads back into the early eighteenth century. A frontispiece of 1717 already expressed the idea of an “open future” conceived secularly as a “space of time” to be shaped by human beings according to their own interests and guided by the experiences of the past. The article closes with a discussion of the reasons for the return of religious ways of thinking in the late Enlightenment, which becomes particularly apparent in universal- historical expectations of the future.
