 Though allowing that these characterisations of people with delusions can be correct, she argues that these failures of so-called agential rationality can also be found in people who do not have delusions.Bortolotti holds that the status of thoughts which subjects do not endorse (such as inserted thoughts) as beliefs is in question, but that beliefs that are both endorsed and self-ascribed contribute to one's conception of self as part of a self-narrative.She concludes her book by rejecting the rationality constraint on belief ascription.
