What is the term for believing that counterfactual statements do not have definite truth values? i.e., that the only possible world is the actual world.

Also are there any philosophers known for that belief?

  • Error theorist? Not specific to counterfactual (it can apply to laws of nature, morality...). Apr 25 '15 at 12:18
  • See also actualism plato.stanford.edu/entries/actualism Apr 25 '15 at 12:22
  • Your 'i.e.' doesn't follow, one can accept that counterfactuals do not have truth values without believing that the only possible world is the actual world.
