Understanding Categorical Syllogism Figures and Structures

This question requires matching the four figures of a categorical syllogism with their respective structural representations. A categorical syllogism is a deductive argument consisting of three parts: a major premise, a minor premise, and a conclusion. Each part contains a categorical proposition. The key to identifying the figure is the position of the middle term (M) in the premises. The major term is denoted by 'P' and the minor term by 'S'. The conclusion always has the structure S-P.

Defining Syllogism Terms and Structure

• S (Minor Term): The subject of the conclusion.
• P (Major Term): The predicate of the conclusion.
• M (Middle Term): The term that appears in both premises but not in the conclusion.

Analyzing Each Figure

First Figure (A)

In the First Figure, the middle term (M) is the subject of the major premise and the predicate of the minor premise.

• Major Premise Structure: M-P
• Minor Premise Structure: S-M
• Conclusion Structure: S-P
• Combined Representation: M-P, S-M $\rightarrow$ S-P
• This corresponds to Structure I in List-II.

Second Figure (B)

In the Second Figure, the middle term (M) is the predicate of both the major and minor premises.

• Major Premise Structure: P-M
• Minor Premise Structure: S-M
• Conclusion Structure: S-P
• Combined Representation: P-M, S-M $\rightarrow$ S-P
• This corresponds to Structure II in List-II.

Third Figure (C)

In the Third Figure, the middle term (M) is the subject of both the major and minor premises.

• Major Premise Structure: M-P
• Minor Premise Structure: M-S
• Conclusion Structure: S-P
• Combined Representation: M-P, M-S $\rightarrow$ S-P
• This corresponds to Structure III in List-II.

Fourth Figure (D)

In the Fourth Figure, the middle term (M) is the predicate of the major premise and the subject of the minor premise.

• Major Premise Structure: P-M
• Minor Premise Structure: M-S
• Conclusion Structure: S-P
• Combined Representation: P-M, M-S $\rightarrow$ S-P
• This corresponds to Structure IV in List-II.

Matching the Lists

Based on the analysis of each figure:

• Figure A (First) matches Structure I.
• Figure B (Second) matches Structure II.
• Figure C (Third) matches Structure III.
• Figure D (Fourth) matches Structure IV.

Therefore, the correct matching is A-I, B-II, C-III, D-IV.

Final Answer

The correct option that accurately matches List - I with List - II is:

A-I, B-II, C-III, D-IV
