The late reflections of G.W. Leibniz on eternal return have often been dismissed as insignificant as regards his wider philosophy. This may be due to the prevalent championing of his optimistic views on the continual progress of humanity, which seem to contradict the notion of eternal return. Walter Benjamin and Gilles Deleuze both put forward concepts of eternal return that form part of their respective critiques of historical progress, yet these have rarely been read in conjunction with their views on (...) Leibniz. This article argues, first, that for Leibniz progress and return are not contradictory, and second, that Benjamin’s and Deleuze’s concepts of return were informed, in different ways, by their readings of Leibniz, and specifically by his conception of multiple worlds as the spatial equivalent of eternal return. In doing so I will shed light on the contribution of Leibniz’s philosophy not only to the progressive theories of history put forward during the Enlightenment, but also to the critique of these very visions.
