Question 1
Given that all women are mortal, and suppose that A is a woman, what can we conclude about A?
- We are given two logical statements:
- Major premise (general rule): All women are mortal.
- Minor premise (specific fact): A is a woman.
- In deductive reasoning, if a general rule applies to an entire group and an individual belongs to that group, the rule must also apply to that individual.
- Therefore, we can deduce a definite conclusion about A.
Step 1 · Identify the Given Premises
We are given two premises:
-
General statement: All women are mortal.

-
Specific fact: A is a woman.

Step 2 · Deduce the Conclusion
Since A belongs to the group of women, and all women are mortal, it logically follows that:
A is mortal.
- Assuming the Converse: Incorrectly assuming that being mortal means someone is necessarily a woman. Deductive logic works from the whole group to the subset, not in reverse.
- Inductive vs. Deductive Confusion: Treating the deduction as an uncertain guess or generalization rather than a logically guaranteed fact based on the given premises.
