3. Since we have spoken of corporeity, it must be analyzed. Is it a
composite of all qualities, or does it constitute a form, a "reason,"
which produces the body by presence in matter? If the body be the
composite of all the qualities together with matter, this totality of
qualities will constitute corporeity. But if corporeity be a reason
which produces the body by approaching matter, doubtless it is a reason
which contains all the qualities. Now, if this reason be not at all a
definition of being, if it be a reason productive of the object, it
will not contain any matter. It is the reason which applies itself to
matter, and which, by its presence, produces the body there. Body is
matter with indwelling "reason." This "reason," being a form, may be
considered separately from matter, even if it were entirely inseparable
therefrom. Indeed, "reason" separated (from matter), and residing
in intelligence, is different (from "reason" united to matter); the
"Reason" which abides within Intelligence is Intelligence itself. But
this subject (I shall) refer to elsewhere.[64]
