sanctions and even recommends what actually leads to the worst outcome. Douglas W. Portmore has suggested that these and other problems of actualism and possibilism can be avoided by constraining what counts as a genuine alternative for the agent. On his view, it is a requirement that the agent has rational control over the event in question. For example, eating only one cookie and stopping afterward only is an option for Gifre if she has the rational capacity to repress her temptation to continue eating. If the temptation is irrepressible then this course of action is not considered to be an option and is therefore not relevant when assessing what the best alternative is. Portmore suggests that, given this adjustment, we should prefer a view very closely associated with possibilism called maximalism.
