A Counterexample to the Uniqueness Thesis

  • Matthew KopecEmail author


In this essay, I present a straightforward counterexample to the Uniqueness Thesis, which holds, roughly speaking, that there is a unique rational response to any particular body of evidence.


Uniqueness Epistemic permissiveness Disagreement Subjective bayesianism Epistemic instrumentalism
