Subjects experiencing thought insertion disown thoughts they are introspectively aware of. According to what I call “the rationality hypothesis”, thought-insertion reports are not merely intelligible, but also express, or potentially express, fully rational judgments in the light of highly disruptive experience. I argue that the hypothesis is ethically and theoretically motivated, and provides two insights into the philosophical significance of reports by subjects with schizophrenia. First, the reports can be seen as evidence that rational judgments of ownership of a thought (...) prioritize agency awareness over introspective awareness of it. This point fits with an integrative account of thought insertion at the personal and mechanistic levels. Second, rational and competent uses of the first person purely based on introspection do not necessarily involve a full-fledged first-person perspective over one’s thoughts. This suggests that agency awareness, and not introspection as such, is primarily involved in determining the reference of the first person featuring in the judgments. (shrink)

The traditional epistemological problem of other minds seeks to answer the following question: how can we know someone else's mental states? The problem is often taken to be generated by a fundamental asymmetry in the means of knowledge. In my own case, I can know directly what I think and feel. This sort of self-knowledge is epistemically direct in the sense of being non-inferential and non-observational. My knowledge of other minds, however, is thought to lack these epistemic features. So what (...) is the basic source of my knowledge of other minds if I know my mind in such a way that I cannot know the minds of others? The aim of this paper is to clarify and assess the pivotal role that the asymmetry in respect of knowledge plays within a broadly inferentialist approach to the epistemological problem of other minds. The received dogma has always been to endorse the asymmetry for conceptual reasons and to insist that the idea of knowing someone else's mental life in the same way as one knows one's own mind is a complete non-starter. Against this, I aim to show that it is at best a contingent matter that creatures such as us cannot know other minds just as we know a good deal of our own minds and also that the idea of having someone else's mind in one's own introspective reach is not obviously self-contradictory. So the dogma needs to be revisited. As a result, the dialectical position of those inferentialists who believe that we know about someone else's mentality in virtue of an analogical inference will be reinforced. (shrink)

Thought insertion is a condition characterized by the impression that one's thoughts are not one’s own and have been inserted by others. Some have explained the condition as resulting, in part, from impaired or defective self-knowledge, or knowledge of one’s mental states. I argue that such models do not shed light on the most puzzling feature of thought insertion: the patient’s experience that an introspected thought does not feel like her own. After examining ways in which existing versions of the (...) model might address this worry, I propose a significant modification. I argue that the experience of disownership consists in a rational indifference that one feels towards one’s inserted thought. I further contend that the experience is generated by an underlying absence of an expectation of rational authority towards the inserted thought, such that the patient does not expect her thought to reflect, or be shaped by, her own rational considerations. I defend my proposal using empirical studies from cognitive and social psychology which suggest that we ordinarily have and experience an expectation of rational authority towards a certain subset of our thoughts, and direct analysis of patient reports, which strongly suggest that it is this expectation and the corresponding experience that thought insertion patients lack.

There are a number of conflicting accounts of thought insertion, the delusion that the thoughts of another are inserted into one’s own mind. These accounts share the common assumption of realism: that the subject of thought insertion has a thought corresponding to the description of her thought insertion episode. I challenge the assumption by arguing for an anti-realist treatment of first-person reports of thought insertion. I then offer an alternative account, simulationism, according to which sufferers merely simulate having a thought (...) inserted into their heads. By rejecting realism, the paper undermines a widespread explanatory framework that unites otherwise competing cognitive models of thought insertion. (shrink)

This essay presents a new account of thought insertion. Prevailing views in both philosophy and cognitive science tend to characterize the experience of thought insertion as missing or lacking some element, such as a ‘sense of agency’, found in ordinary first-person awareness of one's own thoughts. By contrast, I propose that, rather than lacking something, experiences of thought insertion have an additional feature not present in ordinary conscious experiences of one's own thoughts. More specifically, I claim that the structure of (...) an experience of thought insertion consists of two distinct elements: a state of ordinary first-person awareness and a sense that this state of awareness is highly unusual. In addition to modeling the experience of thought insertion, I also explain how a delusional pattern of thinking could lead someone who has this kind of experience to adopt a belief that some other entity is inserting thoughts into her mind. Finally, I briefly sketch a neurocomputational framework that could be developed to explain the sense that one's state of first-person awareness is highly irregular. (shrink)
