German mysticism reaches its culmination in the Görlitz cobbler, Jacob Böhme (1575-1624; _Aurora, or the Rising Dawn_; _Mysterium Magnum, or on the First Book of Moses_, etc. The works of Böhme, collected by his apostle, Gichtel, appeared in 1682 in ten volumes, and in 1730 in six volumes; a new edition was prepared by Schiebler in 1831-47, with a second edition in 1861 _seq_.). Böhme's doctrine[1] centers about the problem of the origin of evil. He transfers this to God himself and joins therewith the leading thought of Eckhart, that God goes through a process, that he proceeds from an unrevealed to a revealed condition. At the sight of a tin vessel glistening in the sun, he conceived, as by inspiration, the idea that as the sunlight reveals itself on the dark vessel so all light needs darkness and all good evil in order to appear and to become knowable. Everything becomes perceptible through its opposite alone: gentleness through sternness, love through anger, affirmation through negation. Without evil there would be no life, no movement, no distinctions, no revelation; all would be unqualified, uniform nothingness. And as in nature nothing exists in which good and evil do not reside, so in God, besides power or the good, a contrary exists, without which he would remain unknown to himself. The theogonic process is twofold: self-knowledge on the part of God, and his revelation outward, as eternal nature, in seven moments. [Footnote 1: Cf. Windelband's fine exposition, _Geschichte der neueren Philosophie_, vol. i. §19. The following have written on Böhme: Fr. Baader (in vols. iii. and xiii. of his _Werke_); Hamberger, Munich, 1844: H. A. Fechner, Görlitz, 1857; A. v. Harless, Berlin, 1870, new edition, Leipsic, 1882.] At the beginning of the first development God is will without object, eternal quietude and rest, unqualified groundlessness without determinate volition. But in this divine nothingness there soon awakes the hunger after the aught (somewhat, existence), the impulse to apprehend and manifest self, and as God looks into and forms an image of himself, he divides into Father and Son. The Son is the eye with which the Father intuits himself, and the procession of this vision from the groundless is the Holy Ghost. Thus far God, who is one in three, is only understanding or wisdom, wherein the images of all the possible are contained; to the intuition of self must be added divisibility; it is only through the antithesis of the revealed God and the unrevealed groundless that the former becomes an actual trinity (in which the persons stand related as essence, power, and activity), and the latter becomes desire or nature in God.
