The book’s first half draws on the scholarship of international specialists—as well as new translations of the original German texts—to present Marx the anti-theorist, a political journalist deeply skeptical about what happens when the professoriate sits down to "theorize" about social worlds. The second half appeals to this modified portrait of Marx and charts a new course beyond both actually existing religious studies and contemporary genealogies of the religion category. The result, perhaps, is an academic study of religion worth having in the twenty-first century.
