but only virtually: and lastly,
because the soul is immediately united to the body as the form to
matter.

Reply Obj. 1: Augustine speaks there of the soul as it moves the
body; whence he uses the word "administration." It is true that it
moves the grosser parts of the body by the more subtle parts. And
the first instrument of the motive power is a kind of spirit, as the
Philosopher says in De causa motus animalium (De mot. animal. x).

Reply Obj. 2: The union of soul and body ceases at the cessation of
breath, not because this is the means of union, but because of the
removal of that disposition by which the body is disposed for such
a union. Nevertheless the breath is a means of moving, as the first
instrument of motion.

Reply Obj. 3: The soul is indeed very distant from the body, if we
consider the condition of each separately: so that if each had a
separate existence, many means of connection would have to intervene.
But inasmuch as the soul is the form of the body, it has not an
existence apart from the existence of the body, but by its own
existence is united to the body immediately. This is the case with
every form which, if considered as an act, is very distant from
matter, which is a being only in potentiality.

EIGHTH ARTICLE [I, Q. 76, Art. 8]

Whether the Soul Is in Each Part of the Body?

Objection 1: It would seem that the whole soul is not in each part of
the body; for the Philosopher says in _De causa motus animalium_ (De
mot. animal. x): "It is not necessary for the soul to be in each part
of the body; it suffices that it be in some principle of the body
causing the other parts to live, for each part has a natural movement
of its own."

Obj. 2: Further, the soul is in the body of which it is the act. But
it is the act of an organic body. Therefore it exists only in an
organic body. But each part of the human body is not an organic body.
Therefore the whole soul is not in each part.

Obj. 3: Further, the Philosopher says (De Anima ii, 1) that the
relation of a part of the soul to a part of the body, such as the
sight to the pupil of the eye, is the same as the relation of the
soul to the whole body of an animal. If, therefore, the whole soul is
in each part of the body, it follows that each part of the body is an
animal.

Obj. 4: Further, all the powers of the soul are rooted in the essence
of the soul. If, therefore, the whole soul be in each part of the
body, it f
