Vendler [Vendler, 1967, Linguistics in philosophy, Ithaca, NY, Cornell University Press] argued on linguistic grounds that a distinction should be made between “events” (our SoAs) and “facts” (our PFs). […] PFs are third-order entities which can be said to be believed, known, or thought; they can be reason for surprise or doubt; they can be mentioned, denied, and remembered; and they can be said to be true or false in relation to the occurrence of some SoA in some world.
