Desire theories of well-being claim that how well someone’s life goes for them is entirely determined by the fulfilment and frustration of their desires. This thesis considers the viability of theories of this sort. It examines a series of objections that threaten to undermine these views. These objections claim that desire theories of well-being are incorrect because they have implausible implications. I consider four main objections over the course of this thesis. The first claims that these theories are incorrect because (...) they implausibly entail that self-sacrifice does not exist. The second claims that these theories are incorrect because they implausibly entail that severe depression does not diminish the well-being of those afflicted by this condition. The third claims that these theories are incorrect because they have implausible implications about the relative importance of fleeting desires, long-standing desires, and fluctuations in desire strength to well-being. The fourth claims that these theories are incorrect because they fail to capture the intuition that desire fulfilments which leave us disappointed and bereft of feelings of satisfaction do not improve well-being. In each of these cases, I find that desire theories of well-being have sufficient resources to refute these objections. The primary finding of this thesis is that many of the arguments against desire theories of well-being are unsuccessful. A secondary set of findings concern observations about the structure of human psychology. (shrink)

This paper explores the possibility of AI-based addendum therapy for borderline personality disorder, its potential advantages and limitations. Identity disturbance in this condition is strongly connected to self-narratives, which manifest excessive incoherence, causal gaps, dysfunctional beliefs, and diminished self-attributions of agency. Different types of therapy aim at boosting self-knowledge through self-narratives in BPD. The suggestion of this paper is that human-to-human therapy could be complemented by AI assistance holding out the promise of making patients' self-narratives more coherent through improving the (...) accuracy of their self-assessments, reflection on their emotions, and understanding their relationships with others. Theoretical and pragmatic arguments are presented in favour of this idea, and certain technical solutions are suggested to implement it. (shrink)

In this chapter, our focus is the role played by notions of rationality in the diagnosis of mental disorders, and in the practice of overriding patient autonomy in psychiatry. We describe and evaluate different hypotheses concerning the relationship between rationality and diagnosis, raising questions about what features underpin psychiatric categories. These questions reinforce widely held concerns about the use of diagnosis as a justification for overriding autonomy, which have motivated a shift to mental incapacity as an alternative justification. However, this (...) approach too has recently been criticized from a mental disability rights perspective. Our analysis of the relationship between mental capacity and rationality is used to illuminate these concerns, and to investigate further the relationship between rationality and psychiatric diagnosis.

In some recent criminal cases in the United States a defense has been mounted based on an affliction known as Dissociative Identity Disorder (DID) (formerly Multiple Personality Disorder). The crux of the defense rests on the proposition that a dominant personality was incapable of appreciating the nature and quality of wrongfulness of conduct caused by an alter personality. This defense has been successful in some cases, but not others, and so philosophers, lawyers, and psychiatrists are now in debate in an (...) attempt to clarify the issues. One of the salient issues involves the question of personal identity between the individual who allegedly committed the offense and the individual who stands accused. Stephen Behnke and Walter Sinnott-Armstrong have recently put forward a test for establishing personal identity in these cases. In this discussion, I present reasons for rejecting their proposal.
