'In Speculative Empiricism, Didier Debaise expertly guides the reader on a remarkable voyage through Whitehead's metaphysical masterpiece, Process and Reality. The juxtaposition of the two title words sets the agenda, giving notice from the start that we will be heading into unexpected territory. Here, speculation will become a matter of experience, and experience, reciprocally, will be imbued with the futurity of potential. The result is a novel pragmatics of becoming which Debaise maps with unerring lucidity and precision, providing both an introduction to key Whiteheadian concepts and a major contribution to the scholarship that will be of equal interest to specialists.' - Brian Massumi, University of Montreal
