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)

Wittgenstein distinguished between two uses of “I”, one “as object” and the other “as subject”, a distinction that Shoemaker elucidated in terms of a notion of immunity to error through misidentification (“IEM”); first-personal claims are IEM in the use “as subject”, but not in the other use. Shoemaker argued that memory judgments based on “personal”, episodic memory are not strictly speaking IEM; Gareth Evans disputed this. Similar issues have been debated regarding self-ascriptions of conscious thoughts based on first-personal awareness, in (...) the light of claims of “thought insertion” in schizophrenic patients. The paper aims to defend a Shoemaker-like line by critically engaging with some compelling recent contributions. Methodologically, the paper argues that to properly address these issues the all-inclusive term “thought” should be avoided, and specific types of thoughts countenanced. (shrink)

Castañeda, Perry and Lewis argued that, among singular thoughts in general, thoughts about oneself ‘as oneself’—first-personal thoughts, which Lewis aptly called de se—have a distinctive character that traditional views of contents cannot characterize. Drawing on Anscombe, Annalisa Coliva has argued that a feature she calls Real Guarantee marks apart de se thoughts—as opposed to others including Immunity to Error through Misidentification that have been proposed for that role. I'll argue that, while her work points to a truly distinguishing feature of (...) the de se, we need an account of the notion other than hers and Echeverri's recent development of it. I'll offer an alternative, drawing on Léa Salje's work. Finally, I'll briefly outline how, thus understood, the Real Guarantee feature could be adequately explained by theories of de se thoughts like the one I favour, even if it is an open option to just explain it away.
