Jakob Böhme (1575–1624), a German shoemaker and religious writer in Görlitz, explains a difficult alchemical expression in a letter to Christian Steinberg. A practical problem confronts a letter writer here. How can one explain what a particular substance means when its familiar qualities may tempt a reader into identifying it too quickly? Böhme approaches the problem by describing what the substance does within the course of his argument.
A reply to a correspondent
[…] a spirituall Being, which is environed with the four Elements, which also changeth the four Elements into one […]
– Jacob Boehme, The Epistles of Jacob Behmen, 1649, Letter XXIII, 17.[1]
He speaks of a spiritual being surrounded by the four elements and able to turn those elements into one. The two movements deserve to be read separately. First the reader imagines something situated in the midst of its surroundings. Then the surroundings themselves undergo a change as what appeared as four distinct things becomes a unity. The wording shifts the emphasis from the number of ingredients to their relation. A vessel in which separate things visibly lose their former arrangement offers one possible image of the shift.
Why the name of a metal is insufficient
In the same passage Böhme introduces the name Mercury and distinguishes its meaning here from an ordinary identification with quicksilver. The difficulty of language thereby becomes tangible for his correspondent. A familiar word may require an act of understanding before it can be attached to an object in view. The brief account of four and one carries that demand particularly well. To follow it, a reader must first attend to difference and then ask what kind of unity those differences could make possible.
