BY WHAT MEANS THE SOUL IS SENSIBLE, AND WHAT IS THE PRINCIPAL AND COMMANDING PART OF IT.
THE Stoics say that the highest part of the soul is the
commanding part of it: this is the cause of sense, imagination, consents, and desires; and this we call the rational
part. From this principal and commander there are produced seven parts of the soul, which are spread through
the body, as the seven arms in a polypus. Of these seven
parts, five are assigned to the senses, seeing, hearing, smelling, tasting, touching. Sight is a spirit which is extended
from the commanding part to the eyes; hearing is that
spirit which from the principal reacheth to the ears ; smelling a spirit drawn from the principal to the nostrils; tasting a spirit extended from the principal to the tongue;
touching is a spirit which from the principal is drawn to
the extremity of those bodies which are obnoxious to a
sensible touch. Of the rest, the one called the spermatical is a spirit which reacheth from the principal to the
generating vessels; the other, which is the vocal and termed
the voice, is a spirit extended from the principal to the
throat, tongue, and other proper organs of speaking. And
this principal part itself hath that place in our spherical
head which God hath in the world.
