"You cannot trust his views on pollution because he drives a large car." This is an example of

  • A. an ad hominem attack
  • B. a false dilemma
  • C. a hasty generalisation
  • D. circular reasoning

Explanation

The argument attacks the person's behaviour rather than examining the merits of what he says, and inconsistency in a speaker does not make their claim false. This particular version is sometimes called tu quoque. The claim about pollution must be assessed on its own evidence.
