Aphor. 36.
Care is to be taken, that experiments be not mixed with experiments; but that every one be onely simple and several: for God and Nature have ordained all things to a certain and appointed end: so that for examples sake, they who perform cures with the most simple herbs and roots, do cure the most happily of all. And in this manner, in Constellations, Words and Characters, Stones, and such like, do lie hid the greatest influences or vertues in deed, which are in stead of a miracle.
So also are words, which being pronounced, do forthwith cause creatures both visible and invisible to yield obedience, aswel creatures of this our world, as of the watry, aëry, subterranean, and Olympick supercelestial and infernal, and also the divine.
Therefore simplicity is chiefly to be studied, and the knowledge of such simples is to be sought for from God; otherwise by no other means or experience they can be found out.
