"Volume II, it is safe to say, is the least read of the three main volumes of Marx's Capital. This relative neglect is unfortunate, because many issues of concern to contemporary Marxists -- the distinction between productive and unproductive labor, the causes of economic crises, the conceptualization of fixed capital, the treatment of social reproduction -- are addressed in Volume II of Capital. Furthermore, a full appreciation of some of the material in Volume III depends upon concepts treated by Marx in the second volume."
This book is a waterfall in the desert of Marxian economics, a readable and digestible guide to much of the difficult passages in Karl Marx's second volume of Capital. Whilst Fox's writing is brief (necessarily abridging much of Marx's frantic and poorly edited analysis), Fox refuses to simplify the complexities of Marx, instead providing a sketch to make Volume 2 significantly more approachable for mere mortals. For those who want help with all three volumes however, I cannot recommend A Guide to Marx's 'Capital' enough!
Tackling Marx Capital Volume 2 this was a much needed read alongside David Harvey's companion to help bring another perspective and help bring more clarity to the chapters Marx (and Engles) had written. I would recommend anybody read this as they read Volume 2 of capital.
