Syllogism — Good men and wise men (disjoint “some” groups possible): Statements: I. Some men are good. II. Some men are wise. Conclusions: I. Some wise men are good. II. Some good men are wise.

Difficulty: Easy

Correct Answer: Neither I nor II follows

Explanation:


Introduction / Context:
Two existential premises can be satisfied by disjoint subsets. Without a premise linking “good” and “wise,” overlap is not compelled.


Given Data / Assumptions:

  • ∃ (Man ∩ Good).
  • ∃ (Man ∩ Wise).


Concept / Approach:
Both conclusions require the intersection Good ∩ Wise among Men to be non-empty. The premises allow that intersection to be empty because they never assert any relationship between Good and Wise.


Verification / Alternative check:
A model with some good-but-not-wise men and some wise-but-not-good men satisfies the premises while falsifying both conclusions.


Final Answer:
Neither I nor II follows.
