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.
