Through a discussion of current perspectives in philosophy of history-especially with a critical approach to Paul Ricoeur's work-and a rigorous reading of Karl Marx's oeuvre, Karl Marx, Historian of Social Times and Spaces proposes a novel interpretation of Marx's concept and method of historical knowledge. In this sense, the examination of Marx's concepts of social space and social time serve to highlight the resources offered by his work, and their possible application in explaining the dynamics of complex multilinear development of human societies and of capitalism in particular.
