 One possible answer is the one we started with: self-promising is a way of staking our respect to add some moral oomph to an intention. This still leaves us wondering where the oomph comes from, if not the threat of a broken promise. Here the friends of self-promising need to find some way that release might be non-trivial even if it is possible – just as Kanygina (forthcoming) argues that self-release requires us to make decisions autonomously, and Schaab (2021) argues that the power of self-release does not fully protect us against the possibility of violation. Fruh (2014, 170) goes some way towards an answer; he argues that, just because one can dissolve an obligation easily, that doesn’t make the act morally meaningless; the dissolution might express something undesirable, such as a deficiency of “moral fiber.” A lack of fiber probably won’t strike fear into evildoers’ hearts. But it is a defect nonetheless.
