Thomason (Un)conditionals

Abstract

Thomason conditionals are sentences of the form if p, ~Kp. Given plausible assumptions, these sentences cause trouble for epistemic theories of indicative conditionals. Our aim is to show that Thomason examples are not indicative conditionals, but alternative unconditionals, in the sense put forward by Rawlins (2013). This hypothesis solves the difficulty and explains certain features that set Thomason examples apart from run-of-the-mill indicative conditionals.
