Approach
- Recognize common fallacies: equivocation, ad hominem, straw man, false dilemma, petitio principii (begging the question).
- Translate argumentative structure into premises and conclusion; test validity and soundness.
Worked example
Problem type: Show validity of: (P → Q), (Q → R) ∴ (P → R). Solution: Hypothetical syllogism; truth table or proof:
- P → Q (Premise)
- Q → R (Premise)
- Assume P (Assumption for →-Intro)
- From 1 and 3, infer Q (→-Elim / Modus Ponens)
- From 2 and 4, infer R
- Discharge assumption: P → R (→-Intro)
7. Example Problem Set with Brief Solutions
- Determine validity: From All A are B; Some C are A. Therefore, Some C are B.
- Invalid (existential import issue): premises do not ensure overlap unless "Some A are B" or domain assumptions hold.
- Prove: (P ∨ Q), (P → R), (Q → R) ∴ R.
- Proof: Cases via ∨-Elim: assume P derive R; assume Q derive R; conclude R.
- Translate: "Only students who study pass."
- ∀x (Pass(x) → Student(x) ∧ Study(x)) or better parse: Only if a person is a student who studies will they pass → Pass(x) → (Student(x) ∧ Study(x)).
- From ∀x (R(x) → S(x)) and ∀x (S(x) → T(x)), infer ∀x (R(x) → T(x)).
- Universal transitivity via ∀-Elim and →-Intro.
