2. JUDGEMENT
Judgment is the act of the mind, which
expresses affirmation, or denial of
relationships that exists between the two
ideas formed in the mind after the process of
simple apprehension is accomplished by the
mind.
This mental operation is designated as the
second act of the mind.
However, it should not be misinterpreted that
simple apprehension precedes judgment
according to the order of time for such
assertion is beyond rational demonstration
owing to the fact that the complete
reasoning process cannot be rationally
broken into different units of actions. Yet,
due to the mind’s limited capacity, books in
philosophy present the whole process by
dividing it into three units namely; simple
3. PROPOSITIO
N
A proposition contains judgment. It is a
judgment expressed in a sentence, or a
sentence pronouncing the agreement or
disagreement between two ideas. However,
not all kinds of sentence
are considered as proposition.
4. ELEMENTS OF PROPOSITION
SUBJECT
Its is the one that
either affirms or
denies something
about the
predicate
PREDICATE
It is the one in which
something is either
affirmed or denied in
whatever manner.
COPULA
The copula (also known
as verb in English
grammar) is the one
which causes the logical
connection when there is
affirmation or separation
(negation) or when there
is a denial expressed in
the whole categorical
proposition.
5. The Copula is expressed
in the use of the following
“be” verbs:
a. Is (am, are)
the copula “IS” is appropriately
applicable in a proposition
which affirms the relationship
existing between the subject
and the predicate.
6. The Copula is expressed
in the use of the following
“be” verbs:
b. Is (am, are) not
the copula “IS NOT” is functional
only in a categorical proposition
which denies the existence of
any relationship between the
subject and the predicate.

The correct form should be:
• Subject
c P
• Copula • Predicat
e
All men are rational.
• Subject
• Copula
• Predicat
e
All men
are
rational.
8. A QUALITY OF PROPOSITION
The quality is affirmative if the
proposition affirms something.
As a result, the proposition itself
is called an affirmative
proposition (not positive
proposition).

9. A QUALITY OF PROPOSITION
The quality is negative if the
proposition denies or negates
something. As a result, the
proposition itself is called a
negative proposition.

10. B. QUANTITY OF
PROPOSITION
The quantity or extension of a proposition is determined by the quantity or
extension
of the subject term. Simply, it means that whatever is the quantity or
extension of the subject term is the quantity embraced by the whole
proposition. Thus, it is safe to assume the following formula for the
convenience of the study:
Subject (Singular) = Proposition
(Singular)
GENERAL TYPES OF PROPOSITION
Subject (Particular) = Proposition
(Particular)
Subject (Universal) = Proposition
(Universal)

PROPOSITION
a. Jose Rizal is a Filipino.
GENERAL TYPES OF PROPOSITION
Jose Rizal (Singular Subject) = Singular
Proposition
EXAMPLES:
b. No non-beliver has a religion.
Non-believer (Universal Subject) = Universal
Proposition
c. Some politicians are lawyers.
Politicians (Particular Subject) = Particular
12. THE ORDINARY
PROPOSITION (A, E, I and O)
To facilitate the study of the proposition in terms of its quality and quantity
Aristotle, the author of logic, has instituted the use of the four basic symbols
A, E, I, and O. These four symbols which are all vowels were derived from two
Latin terms namely; affirmo and nego.
this case, affirmo is the first person, singular, indicative mood, and in the active
voice of
the infinitive verb “affirmare” which means “to affirm” in English. The first two
vowels of affirmo are A and I. Hence, A and I are properly designated here as
affirmative symbols.
On the other hand, the Latin term nego is the first person, singular, indicative
mood, and in
the active voice of the infinitive verb “negare” which means in English “to deny.”
Hence, the
symbols E and O are clearly designated here as negative symbols, being derived
from nego.
13. The following table can help us understand vividly the
appropriate use and interpretation of such use of the
symbols in analyzing the quality and quantity of
propositions.
From the table above, it is clear that the symbols for singular and
universal propositions are the same and the difference lies only in the
quality. Always remember that these symbols are only valid for the
analysis of propositions.
14. Examples:
1. Every Economic Resource Used in Business Is an
Asset.
Analysis:
Proposition’s Quantity (Universal) + A
Quality (Affirmative) =
2. A Lot of Business Are Not Illiquid.
Analysis:
Proposition’s Quantity (Particular) + O
Quality (Negative) =
3. No Internal Control Can Perfectly Prevent
Fraud.
Analysis:
Proposition’s Quantity (Universal) + E
Quality (Negative) =
4. Many Filipino Artists Are Still Unrecognized.
Analysis:
Proposition’s Quantity (Particularl) + I
Quality (Affirmative) =
5. This Book is Affordable.
Analysis:
Proposition’s Quantity (Singularl) + A
Quality (Affirmative) =
15. The general rule is “the predicate of an affirmative proposition is particular,
unless it is singular.” As such, the determinant of the predicate is the
proposition’s quality. However, an exception to the rule is validly invoked
every time the predicate’s quantifier is proven to be singular which causes it
to be singular as well.

The lowest returns to the business this year is also the lowest in the country’s
history.

s:
Proposition’s Quality (Affirmative) =
Immediate Quantifier of the Predicate (Singular) = Predicate (Singular) - an exception to the
general rule
As a rule, the determinant of the predicate is the proposition’s quality. However, an exception to the rule is validly invoked every
time the predicate’s quantifier is proven singular which causes it to be singular as well.
16. The general rule states that “The predicate of a negative proposition is
universal, unless it is singular.” Thus, it holds that negative propositions use a
universal predicate, except if the predicate has an immediate singular
quantifier, which also causes it to be singular.

Predicate

No money economy is spared from inflation.
