 Following Scanlon, Roth analyses the circularity worry in epistemic terms, as a lack of justification for the belief in performance on the part of the promisee. But, argues Roth, intentional beliefs, of the sort we form when we form an intention to do some act don’t typically require epistemic justification. If I intend to take a walk, I come to believe that I will, and that belief is reasonable (ceteris paribus) without any other evidence that I will do so.
