An examination of conception makes evident two distinct
characteristics. First, I may be able to recognize each
individual pencil because of the two common qualities, a
thread of lead and an encasement of some kind. This process of
the knowing mind whereby it recognizes and affirms connections
is called thinking as we have already learned. Here is the
_thinking_ aspect of conception. Second, as the instances of
the observed objects are multiplied, my notion of pencil is
_broadened_. It is a building process where many are cemented
into one; like the blocks of a cement wall. Here we find the
characteristic which enables us to call the process _conception_.
This is the mark which distinguishes conception from all the
other thought processes.
=10. THE JUDGMENT AS A THOUGHT PRODUCT.=
Judging is the process of conjoining and disjoining notions.
The product of judging is the judgment and all judgments are
expressed by means of propositions. A proposition consists of
one subject and one predicate connected by some form of the verb
_be_ or its equivalent.
(1) A judgment may conjoin or disjoin two individual notions.
To wit: Conjoined――This pencil belongs to Albert White.
Disjoined――This pencil does not belong to Mary Smith.
(2) A judgment may conjoin or disjoin two general notions.
Conjoined――Some men are virtuous.
Disjoined――Some men are not virtuous.
(3) A judgment may conjoin or disjoin a general and an individual
notion.
Conjoined――Abraham Lincoln was virtuous.
Disjoined――Edgar Allen Poe was not temperate.
In order that the knowing mind may conjoin notions it must
recognize some mark of similarity or connection. This is the
_thinking_ aspect of the judgment. It is likewise to a certain
degree the judging aspect as the latter is simply a matter of
affirming or denying connections between notions. But thinking
is a broader term than judging. There may be connections
established between a name and a notion. For example in the case
of the dog which the child sees trotting along the sidewalk and
which the mother refers to as a “bow-wow”; the term “bow-wow” is
not a percept and has no meaning independent of its association
with the dog, hence it is not a notion, yet some connection has
been made in the child’s mind between “bow-wow” and his notion
of dog. This is a simple form of thinking, but not of judging,
as the latter affirms or denies connections between _notions_
only.
