To fully grasp Marx's theory of the labour movement, Lapides supplies a deeper insight into the economic analysis underlying it. This book presents Marx's theory of wages and wage labour, previously scattered throughout his writings, in its entirety. The author places the theory in its historical context, locating the sources of Marx's wage theory, its intellectual antecedents and the roots of later controversies, but the primary focus of the work is the actual development of Marx's theory in the words in which he expressed it. In order to reveal the true nature and rich texture of Marx's thought, the author has assembled Marx's own formulations, scattered throughout his numerous works and buried beneath mountains of commentary and criticism. The book provides a faithful record of the complete evolutionary progress of Marx's theory.
