 There are two ways in which a theory’s resulting in an infinite regress can form an objection to that theory. The regress might reveal a bad feature of the theory—a feature that is not the regress itself, that we have independent reason to think is a reason to reject the theory. Or the fact that the theory results in the infinite regress might itself be taken to be a reason to reject the theory. The former cases are the easier ones, since in those cases we do not have to make a judgment as to whether the regress itself is objectionable, we only need to ask about the feature of the theory that the regress reveals. We will look at cases like this first, before turning to cases where the regress itself might be seen as a reason to reject a theory.
