The specialized essays in this collection study whether non-Aristotelian traditions of ancient logic had a role for medieval logicians. Special attention is given to Stoic logic and semantics, and to Neoplatonism.

This volume, the first dedicated and comprehensive companion to medieval logic, covers both the Latin and the Arabic traditions, and shows that they were in fact sister traditions, which both arose against the background of a Hellenistic heritage and which influenced one another over the centuries. A series of chapters by both established and younger scholars covers the whole period including early and late developments, and offers new insights into this extremely rich period in the history of logic. The volume is divided into two parts, 'Periods and Traditions' and 'Themes', allowing readers to engage with the subject from both historical and more systematic perspectives. It will be a must-read for students and scholars of medieval philosophy, the history of logic, and the history of ideas.

Karen Ng sheds new light on Hegel's famously impenetrable philosophy. She does so by offering a new interpretation of Hegel's idealism and by foregrounding Hegel's Science of Logic, revealing that Hegel's theory of reason revolves around the concept of organic life. Beginning with the influence of Kant's Critique of Judgment on Hegel, Ng argues that Hegel's key philosophical contributions concerning self-consciousness, freedom, and logic all develop around the idea of internal purposiveness, which appealed to Hegel deeply. She charts the development of the purposiveness theme in Kant's third Critique, and argues that the most important innovation from that text is the claim that the purposiveness of nature opens up and enables the operation of the power of judgment. This innovation is essential for understanding Hegel's philosophical method in the Differenzschrift (1801) and Phenomenology of Spirit (1807), where Hegel, developing lines of thought from Fichte and Schelling, argues against Kant that internal purposiveness constitutes cognition's activity, shaping its essential relation to both self and world. From there, Ng defends a new and detailed interpretation of Hegel's Science of Logic, arguing that Hegel's Subjective Logic can be understood as Hegel's version of a critique of judgment, in which life comes to be understood as opening up the possibility of intelligibility. She makes the case that Hegel's theory of judgment is modelled on reflective and teleological judgments, in which something's species or kind provides the objective context for predication. The Subjective Logic culminates in the argument that life is a primitive or original activity of judgment, one that is the necessary presupposition for the actualization of self-conscious cognition. Through bold and ambitious new arguments, Ng demonstrates the ongoing dialectic between life and self-conscious cognition, providing ground-breaking ways of understanding Hegel's philosophical system.

The Zhou Changes, better known in the West as I Ching, is one of the masterpieces of world literature. This book, the climax of more than forty years of research in Chinese archaeology, explores the text’s origins in the oracle-bone and milfoil divinations of Bronze Age China and how it transformed over the course of the Zhou dynasty into the first of the Chinese classics. The book provides an in-depth survey of the theory and practice of divination to demonstrate how the hexagram and line statements of the text were produced and how they were understood at the time.
