 In cases of self promise, since the promisor is also the promisee, and so can release herself, then we are faced with Hobbes’ challenge. Many authors have grappled with this puzzle—some, like Liberman (2019) move to drop the promisee release condition, and claim that some sorts of self promise, like vows, cannot be revoked. Others, like Habib (2009) and Schaab (2021), look to accept promisee release and explain Hobbes’ difficulty away.
