On Knockdown Arguments

  • John A. Keller
Critical Discussion


Nathan Ballantyne (Erkenntnis 79, 2014) argues that the knockdown status of certain non-philosophical arguments can be transferred to arguments for substantive philosophical conclusions. Thus, if there are knockdown non-philosophical arguments, there are knockdown philosophical arguments. I show that Ballantyne’s argument is unsound, since arguments that are knockdown in non-philosophical contexts may become question-begging when used to argue for philosophical conclusions.
