Jacob Boehme’s mystical pantheism and dialectical conception of God – in which good and evil are rooted in one and the same being – soon brought him into conflict with Lutheran orthodoxy. It is in 'The Signature of all Things' (Signatura Rerum) that the tenets of Boehme’s theosophy are related in their greatest detail. Casting the reader into the vortex of his cosmological universe, Boehme’s endeavour to express a new sense of the human, divine and natural realms attains its apotheosis in his conception of the Ungrund, the uncertainty that precedes the divine will’s arousing itself to self-awareness.
