In The Theological Origins of Modernity, Michael Gillespie has given us a big book. At once learned and lively, it enters the lists not simply of “origins of modernity” stories, but more particularly of those stories that engage the proudly secular and rational self-image of the age. Among the latter, its most explicit interlocutors are Hans Blumenberg and Martin Heidegger, but its effective resonances and dissonances extend, if more subtly, to Karl Löwith, Leo Strauss, Hannah Arendt, and Amos Funkenstein—and perhaps to the likes of Adorno, Derrida, Deleuze, and others as well. Indeed, in its insistent probing of connections between modern science and late medieval theology, this book is arguably in dialogue not only with a range of continental thinkers, but also with such Anglophone philosophers as Whitehead, Collingwood, and E. A. Burtt.
