Written with exemplary clarity, Robb Dunphy's book provides a useful critical commentary on Hegel's essay, "With what must the beginning of the science be made?", that opens the Science of Logic. It also contributes greatly to our understanding of Hegel's engagement with Pyrrhonian scepticism.--Tanja Staehler, professor of European philosophy, University of Sussex Robb Dunphy's book presents a compelling account of the role that Pyrrhonian scepticism plays in Hegel's philosophy and particularly in Hegel's thinking at the beginning of Logic. Dunphy argues that the oppositional structure of thought emphasized by skepticism makes the problem of how to start thinking philosophy particularly pressing. Dunphy presents a compelling analysis of how Hegel addresses the problem both as it relates to the Phenomenology of Spirit and the Science of Logic.--Stefan Bird-Pollan, assistant professor of philosophy, University of Kentucky In this outstanding new monograph, Robb Dunphy explores one of the most important problematics of Hegel's work, the question of how to begin the dialectical journey of the Science of Logic. Dunphy's book offers a comprehensive textual guide to the complex insights of Hegel's presuppositionless starting point, appropriate for new readers of Hegel as well as advanced scholars.--Nahum Brown, assistant professor of philosophy and religious studies, Chiang Mai University.
