Hegel’s Science of Logic is divided into three books, dealing with the topics of being, essence, and the concept, which appeared in 1812, 1813, and 1816 respectively. For most of the 20th century it was not received with the enthusiasm that often marked the reception of Phenomenology of Spirit. First, as a work of logic most have regarded it as radically outdated and relying on an Aristotelian approach that was definitively surpassed in the later nineteenth century—a view promoted especially by Bertrand Russell in the early years of the twentieth. Thus many readers sympathetic to particular doctrines in Hegel have attempted, contrary to Hegel’s insistence, to quarantine his philosophical approach to particular areas from it. Recently, this skepticism has started to change.
