Question

All men are chairs. John Doe is a man. In logical language, therefore:

• A. John Doe is a chair
• B. John Doe is a human being and therefore he cannot be a chair
• C. A man cannot be a chair in any case
• D. Chairs can be men

Hint:

When faced with absurd premises in logical reasoning, follow the premises as stated for the sake of deduction, even though the conclusion may not make sense in the real world.

Answer 1

The Correct Option is A

This problem illustrates a fallacy or absurd argument where a premise is presented without any real-world basis. The statement “All men are chairs” is an absurd proposition because men cannot be chairs. However, given this flawed premise, the conclusion that “John Doe is a chair” follows logically based on the premise. Here's the reasoning:
- According to the given statement, “All men are chairs,” it asserts that every man is a chair.
- Since “John Doe is a man,” he must, by the illogical premise, also be a chair.
This conclusion is valid only if we accept the absurd premise. However, in real-world logic, this statement is nonsensical, but it is a valid conclusion based on the false premise. Therefore, the answer is (A).
