 This familiar fact – that some wrongs can be done to others but not to ourselves – is called the asymmetry of possibilities (Muñoz and Baron-Schmitt 2022 [Other Internet Resources]). This asymmetry constrains the scope of self-wronging; some naughty interactions are impossible in the one-person case. But this does not rule out all possible obligations to oneself. There are still plenty of problematic things one can do to oneself: bodily harm, property damage, and so on. Could we wrong ourselves by doing such things, or is there something fishy about the very idea of an obligation to oneself?
