This book provides a wide-ranging and in-depth reappraisal of the relation between Marx’s economic theory in Capital and Hegel’s Logic by leading Marxian economists and philosophers from around the world. The subjects dealt with include: systematic dialectics, the New Dialectics, materialism vs. idealism, Marx’s ‘inversion’ of Hegel, Hegel’s Concept logic (universality-particularity-singularity), Hegel’s Essence logic (essence-appearance), Marx’s levels of abstraction of capital in general and competition, and capital as Hegelian Subject.
