PHYSICK, and the parts thereof.
a 1.1 PHYSICK is divided into these places; Of Bodies, Of Princi∣ples, Of Elements, Of Gods, of Place, Of Vacuum: thus especi∣ally; but generally into three places; Of the world, Of Elements, Aitiologick of Causes.
That concerning the VVorld is divided into two parts; whereof one, Contemplation, is common also to the Mathematicks, con∣cerning fixed stars and Planets; as whether the Sun be of the same magnitude as he appears to be, and whether the Moon be so likewise; of their periods and the like; The other contemplati∣on proper only to Physick, to enquire into the essence of these; whether the Sun and Stars consist of matter and form; whether generate or ingenerate, whether animate or inanimate, whether corruptible or incorruptible, whether govern'd by Providence or the like.
The place concerning Causes is likewise twofold; whereof one, Contemplation, is common also to medicinall disquisitions, whereby they enquire concerning the principall part of the soul, and those things which are produced in the Soul & seed, and the like. The other is likewise usurped by the Mathematicks, as, in what manner we see, what is the cause of the visuall pha••tasie;
