"This dictionary is less a pure reference work and more a critical introduction to the complex thought of Quentin Meillassoux. Gratton (Memorial University of Newfoundland, Canada) and Ennis (independent scholar) provide an excellent introduction, placing Meillassoux's philosophy within - but critically at odds with - the Continental tradition. The editors focus on his contributions to a 'speculative materialism' that can lead to a 'speculative ethics' (the focus of their introduction). The A-Z dictionary entries, written by noteworthy scholars in the specialty of speculative realism, are clear and concise, providing explanations of many of Meillassoux's most difficult terms, such as 'factiality' and 'arche-fossil,' as well as general concepts such as phenomenology or science. Each entry indicates where and how Meillassoux uses the term, frequently noting the critical responses to his usage by other scholars. Most entries fill at least a page, and many are as long as three pages, thereby providing substantial explanation of terms. There are also entries for influential figures in the philosopher's work, including Alain Badiou, Georg Cantor, Gilles Deleuze, and Immanuel Kant. The book serves as a worthwhile overview and analysis of Meillassoux, born in 1967 and already a rising figure in the field." - J. Donohoe, University of West Georgia, Choice
