Notes
1
"Qual" is a philosophical play upon words. Qual literally means torture, a pain which drives to action of some kind; at the same time the mystic Böhme puts into the German word something of the meaning of the Latin qualitas; his "qual" was the activating principle arising from, and promoting in its turn, the spontaneous development of the thing, relation, or person subject to it, in contradistinction to a pain inflicted from without.
