Abstract

I defend my arguments in quant-ph/9806002, which have recently been criticized by L. Vaidman (quant-ph/9811092). I emphasize that the correct usage of the ABL rule applies not to a genuine counterfactual statement but rather to a conjunction of material conditionals. I argue that the only kind of valid counterfactual statement one can make using the ABL rule is a ``might'' counterfactual, which is not adequate for the attribution of `elements of reality' to a quantum system.
