THE WORLD OF

Direct
Universals: Categories
An idea which expresses the essence or nature
of a thing as the thing is in itself, without
relation to other things or ideas, is called a
direct universal.
A direct universal considers and manifests only
the comprehension and the intellect pays no
attention to the extension of the idea or how the
comprehension of the idea applies to the
individuals of the extension.
A direct universal expresses the essence or
nature of an object as it is found directly and
immediately in the real order of objects existing
all around us. The extension of the idea is not
considered; the application of the universal to the
individuals and the class is ignored.
There are different types of direct universals
and various philosophers have designed different
ways of organizing them into divisions. For our
purposes, we will use a classification designed by
Aristotle, who considered his categories to be the
supreme and ultimate classes of predicates as found
in our judgments and sentences. These predicates
are direct universals and the categories are the
supreme and ultimate classes of direct
universals.
The categories determined by Aristotle are
ten in number and it's easy to see, once each one
is considered, why his system of categories appeals
to common sense critically examined. These
categories are very practical and very
serviceable. Each one will be explained.
The first category is
Substance.
We've used this word before so it should be
familiar. A substance is a being existing in and
for itself. It doesn't need a subject in which to
exist. A human being, a dog, a stone, a tree, a
house are examples of substances. Each can exist in
itself and for itself. If you ask the following
question, the answer will express the substance:
Who or what is this object?
The second category is
Quantity.
Quantity refers to the extension or number of an
object. Weight and size are examples. "My dog
stands two feet high." "This stone weighs twenty
pounds." If you ask the following question, the
answer will express the quantity: How much or how
big?
The third category is
Quality.
Quality refers to a determining attribute in a
thing. For example: strength, color,
intelligence, temperature, and so on. "This dog is
black." "That woman is really intelligent." "This
stone is hard." If you ask the following question,
the answer will express the quality: What sort of
thing is it?
The fourth category is
Relation.
Relation is the reference or bearing of one
thing to another. For example: maternity,
equality, similarity. "She is a mother." "Sally is
older." "Jane is a teacher." "Peter's hair is
similar to John's hair." If you ask the following
question, the answer will express a relation: To
what or to whom does it refer?
The fifth category is
Action.
Action is the production of an effect in
another. For example: drawing, making, driving,
pounding, eating. "The dog is chewing a bone."
"Sally is drawing a picture." "John is driving his
father's truck." "Peter broke his leg." If you ask
the following question, the answer will express
action: What does it do to another?
The sixth category is
Reaction.
Reaction is the reception of an effect from
another. Examples would include: being
murdered, being lifted, being entrapped, being
thrown, being heated. "The box is dropped." "John's
fingers are burned." "Sally is hurled forward."
"The boy is hit." If you ask the following
question, the answer will express a reaction: What
is done to it?
The seventh category is
When. When
refers to a situation in time. Today, sometime,
a decade ago, and now are examples. "Peter went
there last year." "Jane is going now." "The package
will arrive at noon." If you ask the following
question, the answer will express when: At what
point of time?
The eighth category is
Where. Where
refers to a position in space. Examples of this
are: on the table, in the box, below the top shelf,
at school, up the river. "Sally is downtown." "The
car is in the carport." "The book is on the desk."
If you ask the following question, the answer will
express where: Where is it?
The ninth category is
Posture.
Posture refers to disposition or attitude,
immanent action expressed by an intransitive
verb. Upright, standing, lying down, sideways,
kiddy-corner are examples. "The house is leaning to
the right." "Peter is running." "Sally is resting
on the couch." If you ask the following question,
the answer will express posture: In what
attitude?
The tenth category is
Habitus.
Habitus is the outward modification of one
substance by another, as expressed by the reflexive
verb. Examples include: armed, clothed, being
one's self, praising one's self. "John wears a blue
coat." "The girl is disgusted with herself." "Jane
has a yellow hat on her head." If you ask the
following question, the answer will express
habitus: How surrounded, how equipped, how
conditioned?
Always look to the
primary meaning expressed in the idea in order to
place an idea into its proper category.
For example, "student" and "child"
belong to the category of relation even though they
are substances. "Student" is related to "teacher"
and "child" is related to "parent." These reflect
the primary meanings expressed in the ideas.
Many ideas can be
placed in a category only indirectly or
reductively. For example, parts go into
the category to which the whole belongs. "Arm" is a
part of "body" and belongs in the category of
substance. "Branch" is a part of a "tree" or
"plant" and belongs in the category of
substance.
There is a chart below
that will help you review the above.
