"Jacob Boehme has to be termed the greatest of Christian gnostics. The word gnosis I employ here not in the sense of the heresies of the first centuries of Christianity, but in the sense of knowledge basic to revelation and dealing not with concepts, but with symbols and myths; contemplative knowledge, and not discursive knowledge. This is also a religious philosophy or theosophy. Characteristic for J. Boehme is that he had a great simplicity of heart, a child-like purity of soul."
