Thus Weigel, who begins with Paracelsus, leaves off somewhere near Eckhart--and Eckhart in his boldest mood. But his chief concern is to attack the Bibliolaters (_Buchstabentheologen_) in the Lutheran Church, and to protest against the unethical dogma of imputed righteousness. We need not follow him into either of these controversies, which give a kind of accidental colouring to his theology. Speculative Mysticism, which is always the foe of formalism and dryness in religion, attacks them in whatever forms it finds them; and so, when we try to penetrate the essence of Mysticism by investigating its historical manifestations, we must always consider what was the system which in each case it was trying to purify and spiritualise. Weigel's Mysticism moves in the atmosphere of Lutheran dogmatics. But it also marks a stage in the general development of Christian Mysticism, by giving a positive value to scientific and natural knowledge as part of the self-evolution of the human soul. "Study nature," he says, "physics, alchemy, magic, etc.; for _it is all in you, and you become what you have learnt_." It is true that his religious attitude is rigidly quietistic; but this position is so inconsistent with the activity which he enjoins on the "reason," that he may claim the credit of having exhibited the contradiction between the positive and negative methods in a clear light; and to prove a contradiction is always the first step towards solving it. A more notable effort in the same direction was that of Jacob Böhme, who, though he had studied Weigel, brought to his task a philosophical genius which was all his own. Böhme was born in 1575 near Görlitz, where he afterwards settled as a shoemaker and glover. He began to write in 1612, and in spite of clerical opposition, which silenced him for five years, he produced a number of treatises between that date and his death in 1624.
