Hegelian philosophy is now enjoying an enormous renaissance in the English-speaking world. At the very centre of his work is the monumental Science of Logic. Hegel's theory of subjectivity, which comprises the final third of the Science of Logic, has been comparatively neglected. This volume collects 15 essays on various aspects of Hegel's theory of subjectivity. For Hegel, substance is subject. Anyone aspiring to understand Hegel's philosophy cannot afford to neglect this central topic.
