a) Man's
Soul
The substantial form of the human living body is
called the human soul. As the substantial
form of man, it is that substantial principle which
makes a man an existing being of the human
species, and it is the root-source in man of
all his vital activities.
Now, man has the highest grade of life in living
bodies. He has all the perfections and operations
of plants and of non-human animals; he has the
operations of nutrition, growth, vital generation,
sensation, appetition, locomotion, and, in
addition, he has his own proper or specific
operations called understanding and
willing. The activities or operations of
understanding and willing are called the
operations of rational life. And since
animal means all that plant means
plus the sentient powers and operations, so
man means all that animal means plus
the rational powers and operations. Man is
therefore defined as a rational animal. As
each of the three grades of life in living bodies
is essentially different from, and essentially
superior to the lower grade or grades, it is
manifest that man, while possessing all the
perfections and operations of plant and animal, is
essentially different from these living bodies and
essentially superior to them.
He is an essentially
different kind of living body.
While man has the perfections, powers, and
operations of all three grades of life in living
bodies, he is none the less a single bodily
being. Each human being is one substance, not
three. He has one substantial form, not three
substantial forms. It is the one individual man who
comes into existence by generation, who takes
nourishment and grows, who feels and walks about,
who thinks and makes free decisions. The human
substance is a compound substance, as every bodily
substance is, but it is a single substance, not a
triple one. Man's one substantial form is his
one life-principle or soul. This one soul is
the root-source or principle in man of the material
life of plant and animal which he possesses, and of
the nonmaterial or spiritual life which he
manifests in his rational powers and operations.
Since that which is superior can account for what
is inferior, but not the other way about, we say
that man's spiritual soul can account for even the
material operations of man's life, but that a
non-spiritual soul could not account for the
spiritual operations of man.
Hence we conclude that
man's one soul is a nonmaterial or spiritual
soul. Of this we shall speak again in a
moment.
The human soul is a substance; it is a simple or
uncompounded substance; it is a spiritual
substance; it is an immortal or deathless
substance. We pause briefly upon each of these
truths.
(1) The human soul is
the substantial form of the human body.
It is therefore a substantial thing, a substance.
We shall presently see that it is a spiritual
substance, and by that fact it is different from
the other types of substantial form which actuate
bodies whether living or lifeless; it is in itself
a complete substance. It is not a complete
man, that is, not a complete human
being; it is only part of a human being. But it
is a complete soul, capable of existence by itself
without the body. For a complete substance is one
that can exist and exercise its proper operations
alone; an incomplete substance is one that requires
another substance to be fused with it substantially
so that it may exist and operate. That the human
life-principle or soul is a substance, and not
merely an accidental, is manifest, as we have said,
from the fact it is the substantial formal
constituent of substantial man. Further, man's soul
is the principle of man's vital powers, and these,
in themselves, are accidentals, and must have -- as
all accidentals in the order of nature must have --
a substantial actuality in which to inhere;
man's vital powers are rooted in a substantial
principle, that is, in a substance,
which we call man's substantial form or
soul.
(2) The human soul is a
simple or uncomposed substance. It is
not made of parts. Every substantial form is
simple. For a body which exists as a definite kind
of body by reason of its substantial form is one
body. Even if the form be potentially
multiple, it is never actually multiple. The
life-principle of a plant, for example, is the
substantial form of the plant; and each plant is a
unified thing; it is one substance; it has one
life. This life is manifested in root and stem and
leaf and flower. But it is one life. You do not cut
off part of the life when you pluck a flower
or trim away a branch, though it may be that you
produce, by partition, a completely new plant
with its own one life. Thus every body that
is truly one body, has truly one substantial form,
and the substantial form is itself without
component parts, even though the body has
component parts. This fact is most obvious in
living bodies. But what is true of the lower living
bodies is a fortiori true of man who has all
the perfections of all types of living bodies. For
the rest, as we have seen, it is the one man who
grows, who feels, who is moved by sentient
appetite, who thinks, who wills. Man, who is a
bodily being composed of bodily parts, is
nevertheless one and his life is one and
indivisible. In all his bodily parts man lives
a human life, although he does not exercise
all his human activities in each part. We declare,
therefore, that the principle of man's life, his
soul, is one and indivisible; that it has no parts
of its own; that it is simple.
(3) Man's soul is a
spiritual substance. Substances are of
two possible kinds, material and
nonmaterial or spiritual. A material
substance is either a substance composed of bodily
matter, and hence made up of parts, or it is a
substance which is itself simple but which depends
for existence and activity upon what is bodily. We
have seen that the soul of a plant and the soul of
an animal are material. These souls are not
made up of bodily matter; they are substantial
forms, and hence simple; but they are dependent for
their existence and their operations upon the
organisms or living bodies which they actuate. Now,
man's soul is neither made up of bodily matter or
parts (as we have seen, since it is a substantial
form), nor is it dependent upon the body for its
own specific operations; hence, since it can
operate without the organism, it can exist without
the organism.
How do we know that the soul of man can operate
without the organism? Because it has operations,
even while joined with the organism, which are
essentially superior to any organic function and
which are in themselves independent of bodily
operation. Now, if the soul has operations which
are essentially superior to, and independent of,
bodily structure and function, then the soul itself
is superior to and independent of bodily structure
and function; it is then not dependent on matter;
it is spiritual. For operation follows on
essence; as a thing is, it acts; and if the
soul is supra-organic in activity, it is
supra-organic in essence; it is itself above
the character of the body and is essentially
independent of the body. Now, the soul has
activities which are supra-organic. For the soul
can (or, more properly, man, by reason of
his soul, can) think, and reflect,
and decide.
The operations of understanding and of free will
are in no wise explicable in terms of the body, of
the organism, or of the bodily powers of knowing
and appetizing. There is an old and a true saying
that "the senses are for individual perceptions,
but the intellect is for universal grasps of
reality." The eyes can take in an individual scene,
or a series of such scenes; man, for instance, can
see a tree, or a multitude of trees, or a
succession of trees or of forests. But each visual
perception is an individual thing. No number of
such experiences amounts to the understanding of
what tree means. Yet man has an
understanding of what tree means; he can
define tree, and the definition fits any and
every tree that ever was, or is, or will be, or can
be.
No bodily knowing power (that is, no sentient
faculty) can even begin to lay hold of an essence
as the mind or intellect does. Even a little child
of four or five knows what "a doll" or "a sled"
means; the knowledge is not of this or these
individual toys; it is knowledge of any and every
possible doll, of any and every possible sled. In
its own childish way, the infant has a grasp of an
essence, of what would be expressed by a
definition of doll or sled. Now, such a grasp
of an essence is only possible to a supra-sensible
power. For it is of the very nature of
sense-knowledge that it lays hold of the knowable
things according to their individual marks, limits,
determinants. But the intellect pays no attention
to such limiting things; it prescinds from
them; it abstracts from them; it lays hold
of an essence in universal. Thus in knowing
what a doll is, a child does not need to know the
size of some particular doll, or the color of its
hair, or the material of which it is made, or any
of the other individuating marks which make
a doll this doll or that doll; the child knows what
doll-as-such means, regardless of all
individuating marks.
It is manifest, we repeat, that no sentient
power can thus grasp things in essence, in
universal, by abstraction from individuating marks;
on the contrary, it is by the individuating marks
that a sentient power lays hold of any reality. Man
has, therefore, a knowing-power which is superior
to the bodily knowing-power called
sentiency. In itself, the intellect is a
power superior to and independent of sentiency,
even though in this life the intellect has an
extrinsic and accidental dependency on the senses.
But if the intellect, which is the soul's
knowing-power, is superior to and essentially
independent of the bodily organs, the soul itself
is superior to and independent of bodily
limitations; for the function of the soul shows the
essence of the soul; as a thing acts it is; what is
superior to bodiliness in operation is superior to
bodiliness in essence. The soul of man is,
therefore, nonmaterial; it is spiritual.
Again, the soul can reflect, can turn the
attention of the mind upon the mind; can think of
itself thinking. No bodily power is capable of such
an activity. The soul is, in consequence, superior
to the body in its powers and operations; hence it
is superior in its essence; it is not dependent in
essence and operation on the body; it is not
material; it is spiritual. Once again, man,
by reason of the soul, can choose and decide, can
exercise free will. He can be swayed in his choice
by the consideration of things beyond the reach of
any bodily power, by thoughts of loyalty, of
devotion, of friendship, of love; no sentient power
has any means of grasping these or of appetizing
them. Therefore man has operations which are quite
above the reach and character of bodiliness and
sentiency. It follows that he has a principle of
such operations which is itself beyond the
character of the body, and is thus essentially
independent of the body. In a word, it follows that
man has a soul which independent of matter, and is
therefore spiritual. The soul of man is a
spiritual substance.
(2) Man's soul is an
immortal or deathless substance. Death
is the separation of the substantial form of a
living body and the material of which the body is
made. It is a tearing apart of the life-principle
(a substantial form) and the material substance
which that life-principle informed and made a
living body. In plants and animals death means the
cessation from being of both organism and
life-principle, for both are material, and
they are mutually dependent for the constituting of
the living body which now dies; and they are
mutually dependent for their own existence on their
union which is now dissolved. Thus plants and
animals are mortal, or destructible by
death, in their bodies and in their respective
life-principles or souls. The soul of plant or
animal has no activity independent of the body;
hence it has no existence independent of the body;
when the body-structure is no longer capable of
supporting or subserving the functions of the
life-principle in plant or animal, both the body
and the life-principle cease to be the substantial
things they were.
With man the case is different. Man is
mortal; man dies; man suffers the
dissolution of his substantial constituting
elements; but man's soul does not die. When
a man dies, his soul endures in being. For his soul
is a spirit, not a material thing; his soul is a
complete substance as a soul, although it is not a
complete human being. The human soul cannot
conceivably cease to be except by
annihilation. For the soul exists, it is
independent of the body for its own existence and
its proper functions of understanding and willing.
And the soul is spiritual; it has no parts that can
be thought of as severed or shattered so as to
destroy it. The human
soul, being spiritual, is naturally
immortal. It is a deathless
substance.
The human soul is spiritual, and therefore its
only possible origin is in an absolute and entire
production, that is, in creation by a
Creator. The human soul cannot be generated from
the souls of parents, for the souls of parents are
spiritual and have no parts to give off as seeds or
germs of the soul of offspring. The result of the
union of soul and body is a human being, a human
substance, a human person. For a person is a
complete individual substance, constituted in its
own specific nature, and belonging to the rational
order. In other words, a person is a complete,
individual, autonomous substance, endowed basically
with understanding and free will. Man is a complete
individual substance; he is not a "soul in a body";
he is a single composed substance of
body-and-soul-substantially-united.
While the soul, once separated from the body by
death, can and must continue to exist and to
exercise its proper operations of understanding and
willing; and while, even during bodily life, the
soul is the root-principle of activities which are
beyond the reach of bodily powers, it is none the
less accurate to say that it is the man, the
compound of body-and-soul, that is the author of
all the operations called human. It is the
man that understands and wills, just as it
is the man that grows, senses, moves. A
person rightly says, "I see, I feel,
I walk, I thirst, I think,
I choose"; he does not say that his body
sees or that his eyes see, that his mind thinks,
that his will chooses. For, activities are to be
ascribed to the active substance as such, not to
its parts or powers.
The substantial union of soul and body may be
shown by a simple instance of their interaction.
Suppose that a person of hearty appetite is about
to begin upon a splendid dinner. A telegram is
handed to him; he reads of the death of a near and
dear relative. Immediately his appetite is gone.
Now the appetite for food is manifestly of the
body; it belongs, strictly speaking, to the vegetal
order. But the understanding of marks on paper,
that is, of the telegram, is an activity of the
intellect, a soul faculty. Yet the knowledge taken
in by the intellect has an instant effect upon the
appetizing activity of the body. Here the close
interaction of body and soul indicates their
substantial union; it is the man who has
appetite; it the man who reads and
understands the calamitous news.
The spiritual soul is the one and only soul or
life-principle in a man. It is formally
spiritual and rational. But it is virtually
vegetal and sentient. Just as a five-dollar gold
piece is formally gold, but it is virtually copper
or nickel or silver (because it has the
virtue or power or force or
meaning of many coins of the inferior
metals), so the human soul is virtually (or
in effect or effectiveness) a vegetal soul and an
animal or sentient soul, although in itself, as
such, formally, it is a spiritual and rational
soul.
Each human being has his own soul. It is the
soul which specifies man, that is, makes him
a being of this complete essence or species which
we call the human species. But it is the material,
the bodiliness which the soul informs and makes an
existing human person, that is the principle of
individuation in man. The soul makes a
person an existing human being; but it is not
determinant of the figure, the sex, the
nationality, and so on that mark the
individual human being. The principle of
specification is the substantial form, and the
principle of individuation is matter as marked by
quantity.
The spiritual soul in a living man is in the
entire body and in each part of the body. For the
soul has no parts, it is not part here and part
there; wherever it is it exists in its entirety.
The soul does not exercise all the operations of
which it is the principle in each part of the
living body or organism. But it exists, and
in entirety, in each living part. If a part of the
living body is severed, the soul, the
life-principle, is no longer in such a part. The
soul cannot be mutilated as the body is mutilated;
it cannot be cut down in size, for it has no size.
Even a material soul or life-principle (like every
substantial form) manifests this complete presence
in the whole body which it informs. You may trim
down a rose bush to half its size, but the rose
bush is the same living substance after the
trimming; its life is the same life; its
life-principle has not been cut down.
b) Man's Lower
Faculties
A faculty is a capacity or power for
vital operation. We have already learned that man
is in possession of all the faculties of living
bodies. Man has nutrition, growth, and vital
generation, like the plants. He has sensation,
appetition, and locomotion, like the non-human
animals. And he has understanding and will. Because
man has all these faculties, in addition to the
bodily character of his being which he holds in
common with nonliving bodies, he has been called "a
macrocosm" or "a world in little."
Man's vegetal and sentient faculties are called
his lower faculties. His understanding (that is,
his mind, intellect, intelligence, reason) and his
will are his higher faculties.
Faculties are powers or capacities, distinct
from the substance which possesses and uses them,
for the immediate exercise of vital
operations.
Faculties are said to inhere in a
subject. That which has faculties is the
subject of these faculties. Man is, of course, the
subject of all his faculties. But man is a
composite being, and his faculties are to be more
precisely assigned than they are in a general
ascribing of them to man as a whole. Some of his
faculties belong to the living body, some
belong to the soul. In other words, some of
man's faculties are proper to the composite
of body-and-soul, while some are proper to
the soul alone. We discern this fact even as we
declare that man in his whole being is the
possessor and use of faculties, and that man's soul
(that is, his substantial form) is the
root-principle of all his activities. The
lower faculties have their proper subject in
the composite of man's body-and-soul; the higher
faculties have their proper subject in man's
soul.
We need not pause upon man's vegetal faculties,
for we have considered these in our study of
vegetal life in general. It is manifest that man
has the faculties of nutrition, growth, and
generation. Man has, in a word, true
plant-life.
(1) Man has also the
sentient faculties, first of which is
"sensation." This word is used here in
the meaning of sensing-power and
sensing-activity. In the common speech of
every day, the word sensation suggests
something startling or exciting; it has not that
meaning in our present use of it. Here it means the
power to know things by use of special
faculties called senses, and it is sometimes
employed to indicate the activity of
actually exercising this power.
Things sensed (or known by sensation) are
said to be perceived. Each item sensed is a
percept, and a man's sense-knowledge of
anything is often a collection of percepts, as, for
example, his sense-knowledge of a rose may be a
combination of percepts gathered by sight, smell,
and touch.
Each sense has its own proper object. The
proper object of a sense is that which can be
perceived by this sense alone. Objects that can be
directly perceived by two or more senses are called
common objects. Objects that are not
directly sensed, but are known by experience to be
associated with what is sensed, are called
accidental objects. Thus, a man sees an
apple; as a colored object, it is perceived
by sight alone; as a round object, it can be
known by sight and by touch; as an object of
sweet flavor it can be known directly by the
sense of taste alone, but the man who knows apples
can see that it is a sweet apple, for he knows by
experience that apples of that type are sweet; this
"seeing" that the apple is sweet is
accidental perception.
The system of bodily parts or organs by which
man exercises sentiency is the cerebrospinal
system, which consists of the brain and the spinal
cord, the cerebrospinal nerves, and the external
(or peripheral) sense-organs. The external senses
(sight, hearing, taste, smell, touch) have their
organs in the outer body, but their findings are
conveyed to the brain by nerves. The internal
senses (sentient consciousness, imagination,
sentient memory, and estimation) have their organs
in the brain itself. External sensation is
normally, and during man's waking hours,
immediately recorded in imagination and
consciousness. Imagination also retains and, under
stimulus, evokes the recorded images of external
sensations. Sentient memory has the single task of
recognizing an evoked imagination-image as
something experienced in the past. Estimation is an
awareness of usefulness or harmfulness (of
desirability or undesirability) in a sensed
object.
(2) The second sentient
operation is appetition or appetency.
This operation is the tendency, the striving,
towards what is sensed as desirable and away from
what is sensed as undesirable or harmful. The
tendency of any body (living or lifeless) to an
activity is called natural appetency; such,
for instance, is the tendency of a body to fall
towards the center of the earth, or the tendency of
a tree to grow to maturity and fruitfulness. The
tendency born of sense-knowledge which
inclines the sentient creature towards or away from
an object, is called sentient appetency. We
shall presently learn that the tendency born of
intellectual knowledge of the desirability or
undesirability of an object is called intellectual
appetency or the will.
Since a sentient creature rather
undergoes than elicits the tendency called
appetition, the several classes of appetitive
strivings towards or away from an object are called
passions. Passion in this present use
means any manifestation of the sentient appetency.
There are two main types of passions, the
appetites of simple tendency (formally called
the concupiscible appetites or passions) and
the appetites of tendency in the face of some
obstacle (formally called the irascible
appetites or passions).
The first class includes these appetites or
passions:
- Love - Hatred,
- Desire - Aversion,
- Joy - Sadness.
The second class comprises these passions:
- Hope - Despair,
- Courage - Fear,
- Anger.
The passions are all tendencies, positively or
negatively, towards good, and they are all,
in some sense, variants of love. The
passions are good in themselves, although in man
(because of man's natural weakness) they tend to be
inordinate and thus productive of both physical and
moral evil in a person who is not alert and
decisive in holding them, at least in their
effects, under the control of a well-disposed
will.
(3) The sentient
faculty of "locomotion" is the power of spontaneous
movement from place to place. It is a
power exercised in the light of sentient knowledge.
Certain plants, like the tumbleweed, move about,
but these have no faculty of locomotion, for their
movements are not the result of knowledge.
Locomotion is a faculty which, in many cases, makes
possible the attaining of the object of appetition.
Man's organ of locomotion (like that of all animals
possessing this faculty) is the organism or living
body, especially in its elements of muscles and the
skeletal framework.
