1What is the primary defining characteristic of a valid deductive argument in formal logic?
A.If all the premises are true, the conclusion must necessarily be true.
B.The conclusion provides new empirical knowledge not contained in the premises.
C.The truth of the conclusion is probable based on statistical evidence.
D.The premises are derived entirely from sensory observation and experiment.
Explanation: A deductive argument is valid if and only if it is impossible for all its premises to be true while its conclusion is false. The truth of the premises strictly guarantees the necessary truth of the conclusion.
2Which fundamental Law of Thought states that a proposition cannot be both true and false at the same time and in the same respect?
A.Law of Non-Contradiction
B.Law of Identity
C.Law of Excluded Middle
D.Law of Sufficient Reason
Explanation: The Law of Non-Contradiction (A is not non-A) asserts that two contradictory propositions cannot both be true simultaneously in the same context. It forms one of the foundational laws of traditional deductive logic.
3According to the Law of Excluded Middle in traditional logic, which statement is always true regarding any proposition P?
A.P must be either true or false, with no third alternative.
B.P is identical to itself under all circumstances.
C.P must be proved by empirical scientific experimentation.
D.P cannot be asserted without prior deductive verification.
Explanation: The Law of Excluded Middle (Principium Exclusi Tertii) asserts that between truth and falsehood there is no middle ground: a proposition P is either true or false.
4In the standard categorical proposition 'All philosophers are thinkers', which element functions as the copula?
A.are
B.All
C.philosophers
D.thinkers
Explanation: The copula is the connecting verb (such as 'is' or 'are') that joins the subject term ('philosophers') and the predicate term ('thinkers') and expresses the quality of the proposition.
5Which letter symbol represents a Universal Negative categorical proposition in traditional Aristotelian logic?
A.E
B.A
C.I
D.O
Explanation: The four standard forms are A (Universal Affirmative), E (Universal Negative), I (Particular Affirmative), and O (Particular Negative). The letter E comes from the Latin 'nEgo' (I deny).
6What is the form of an 'O' proposition in standard categorical logic?
A.Some S is not P
B.All S is P
C.No S is P
D.Some S is P
Explanation: An 'O' proposition is a Particular Negative proposition, written in standard form as 'Some S is not P'. The vowel O originates from the second vowel in Latin 'negO'.
7Which terms are distributed in an 'E' categorical proposition ('No S is P')?
A.Both the Subject and the Predicate terms
B.Only the Subject term
C.Only the Predicate term
D.Neither the Subject nor the Predicate term
Explanation: An 'E' proposition ('No S is P') denies inclusion completely between both classes, so it refers to every member of the subject class and excludes every member of the predicate class, distributing both terms.
8Which categorical proposition type distributes NEITHER its subject nor its predicate term?
A.I proposition (Particular Affirmative)
B.A proposition (Universal Affirmative)
C.E proposition (Universal Negative)
D.O proposition (Particular Negative)
Explanation: An 'I' proposition ('Some S is P') refers to at least one indefinite member of S and asserts partial inclusion in P without making a statement about all members of either class, leaving both undistributed.
9In the Traditional Square of Opposition, what is the logical relationship between an 'A' proposition ('All S is P') and an 'O' proposition ('Some S is not P')?
A.Contradictory
B.Contrary
C.Sub-contrary
D.Subalternation
Explanation: Diagonal propositions in the Square of Opposition (A and O, E and I) are Contradictories. They differ in both quality and quantity, meaning exactly one must be true and the other false.
10What is the relationship between two universal propositions that differ only in quality (A: 'All S is P' and E: 'No S is P')?
A.Contrary
B.Contradictory
C.Sub-contrary
D.Subaltern
Explanation: Contraries are universal propositions differing in quality. Under traditional logic, both cannot be true simultaneously, though both may be false.

UPMSP Intermediate Logic Study Tips from Top Performers

1Memorize the distribution of terms rule (ASEB P-O-N-E / A-Subject, E-Both, I-None, O-Predicate) to quickly identify syllogistic fallacies.
2Master the Square of Opposition relationships: Contradictory (A-O, E-I), Contrary (A-E), Sub-contrary (I-O), and Subalternation (A-I, E-O).
3Understand the key distinctions and canons of Mill's Five Experimental Methods, especially distinguishing between Method of Agreement and Method of Difference.
4Practice conversion and obversion rules for all four categorical proposition types (A converts by limitation to I; E converts simply to E; I converts simply to I; O cannot be converted).
5Learn to identify informal fallacies by their classical Latin names and definitions, such as Argumentum ad Hominem, Ignoratio Elenchi, and Petitio Principii.
