Following the success of 'Of Errors & Truth', published in 1775, this second book by the Unknown Philosopher (Louis-Claude de Saint-Martin), published in 1782, continues his theories of the relationships between God, Man and Nature, and goes on to provide an exegesis on the origin of religion, tracing it through the early civilizations to the Prophets of the Old Testament, and introduces the Book of Man, the actions of the Repairer, and finally the End of Times.
