The objective of this book is to provide a methodology and a theoretical paradigm based on Marx's sensuous universal and Merleau-Ponty's corporeal intentionality. It will serve the humanities and social sciences as a means for founding inquiry on concrete experience. Readers will find that the book is not a repackaging of Marx and phenomenology, but rather, it bears an internal critique of the enterprise. The authors' contribution is to ground the sensuous universal as the science of experience that is required by the Marxian project, as well as by the new phenomenology of world theorising.
