“This work is original and brilliant as the first full-length study of the mystical background to Hegel. Cyril O’Regan’s work is a ground-breaking study that will enable readers of Hegel to understand him within the context of the mystical tradition that he claimed as his own. For he made no secret of his filiation with the esoteric strands of Christian mysticism and this was clearly the way he was understood by F. C. Bauer, as well as Feuerbach, Engels, Marx and many of his immediate successors. It has always struck me as a major lacuna in Hegel scholarship that such a study had not appeared. Now it has been filled in considerable measure.”
