William Blake has long been regarded as something of an enigma, and his poetry, although much loved by young and old, seen as esoteric and mysterious. His 'natural supernaturalism', personal mythology and vision can leave readers dazzled by the intensity and passion of his verse. In this outstanding work, Chesterton goes right to the heart of the matter and addresses the question of whether Blake's genius was tainted by madness or whether his peculiar outlook on the world was the key to his success. With a detailed exposition of Blake's life, and by weaving lucid explanations of his philosophy and religion into a discourse on his poetry, Chesterton has produced a remarkable and sensitive biography.
