These are then two arts which enclose man in man; or, rather, which enclose the being in its work, and the soul in its acts and in the production of its acts, as our former body was entirely encased in the creations of its eye, and surrounded with sight. By means of two arts it wraps itself up, in two different ways, in their inner laws and wills, which are figured forth in one material or another, stone or air.
