Stephen Houlgate's long-awaited two volumes on Hegel's Logic of Being offer a thorough presentation and a detailed reconstruction of the Doctrine of Being, which constitutes the first part of the first division of Hegel's Science of Logic (appeared in 1812 in the first edition; revised in the second edition of 1832 published after Hegel's death). The first volume takes on the logic of Quality and the transition to Quantity while the second volume addresses the logic of Quantity and Measure leading up to the transition to Essence. Along with the Doctrine of Essence, the Doctrine of Being occupies the first main division of Hegel's Logic or Objective Logic, which is followed by the Subjective Logic, or Doctrine of the Concept, as its second main division. Within Hegel's philosophical system, the Logic is followed by the Philosophy of Nature and the Philosophy of Spirit, the three main parts of the Encyclopaedia of the Philosophical Sciences (appeared in the three editions of 1817, 1827, 1830). Chronologically, but also systematically (at least in a qualified way),1 the Logic is preceded by the 1807 Phenomenology of Spirit. This brief sketch may help us locate the object of Houlgate's volumes within Hegel's philosophy as a whole.
