He is Professor of History of Philosophy at the National University of Distance Education. He specializes in German philosophy from the Enlightenment and Marx, on the field regularly published in the German specialized media. From concerns about the existence of a "place for the intellectual freedom that exceeds its inescapable decisively phagocytosis by the market" and a "classic" mood, JM Ripalda exercises the unique and free operation of reading and rewriting certain texts philosophical, accompanied by two "far archangels" (J. Derrida and F. Jameson) and two "guardian angels" (Peter and Christa Bürger). In 1977 he published his first book on Hegel, translated into Castilian title The divided nation. Roots of a bourgeois thinker GWF Hegel (1978). Around this same philosopher has given, among other works, an annotated real Philosophy (1984) edition and commentary to Hegel's Philosophy of Spirit (1993). In Editorial Trotta has published works End of classicism. Again with Hegel (1992) and De Angelis. Philosophy, market and postmodernism (1996) and The Limits of dialectics (2005).
