Overview
This document comprises reading exercises from Copi's Introduction to Logic, 14th Edition, focusing on syllogistic analysis. Students are instructed to rewrite syllogisms in standard form and classify them by mood and figure, with worked examples demonstrating the systematic six-step procedure for logical analysis.
What this coursework covers
- Instructions and procedural guidelines for syllogism standardization
- Worked example problem showing complete step-by-step analysis

6.1 INSTRUCTIONS
Rewrite each of the following syllogisms in standard form, and name its mood and figure. (Procedure: first, identify the conclusion; second, note its predicate term, which is the major term of the syllogism; third, identify the major premise, which is the premise containing the major term; fourth, verify that the other premise is the minor premise by checking to see that it contains the minor term, which is the subject term of the conclusion; fifth, rewrite the argument in standard form—major premise first, minor premise second, conclusion last; sixth, name the mood and figure of the syllogism.)
Example Problem
No nuclear-powered submarines are commercial vessels, so no warships are commercial vessels, because all nuclear-powered submarines are warships.
Example Solution
Step 1. | The conclusion is “No warships are commercial vessels.” | |
Step 2. | “Commercial vessels” is the predicate term of this conclusion and is therefore the major term of the syllogism. | |
Step 3. | The major premise, the premise that contains this term, is “No nuclear-powered submarines are commercial vessels.” | |
Step 4. | The remaining premise, “All nuclear-powered submarines are warships,” is indeed the minor premise, because it does contain the subject term of the conclusion, “warships.” | |
Step 5. | In standard form this syllogism is written thus: | |
No nuclear-powered submarines are commercial vessels. | ||
Step 6. | The three propositions in this syllogism are, in order, E, A, and E. More Philosophy samples | |
