In lieu of an abstract, here is a brief excerpt of the content:Is Expertise-by-Experience Impossible?The author reports no conflict of interests.In his article, "Experience and expertise: Can personal experience of mental illness make someone an expert?" Abdi Sanati uses Wittgenstein's arguments on private language and Ryle's philosophy of knowledge to critique the concept of Expertise-by-Experience. The principal argument is that introspection on personal experiences cannot constitute the basis for knowledge underpinning expertise. From the start, and in various sections of the (...) article, Sanati highlights the importance of patient involvement in the delivery of mental healthcare. He clarifies the contributions made by the community of patients in the design and delivery of mental health services are not only valuable but also necessary and long overdue. He argues patients must be involved in their care independently of how knowledgeable they are and, in a way, considers the attribution of a status of expertise as potentially counterproductive, since it may restrict the involvement of those who do not possess this status. I will explore initially the core premise made by Sanati that is then subjected to a thorough philosophical scrutiny. This is important because, as we shall see, there can be a different reading of the core premise that throws a slightly different lens into the Inquiry made. We'll end by discussing the future of expertise in the unfamiliar landscape of artificial intelligence (AI) systems, such as large language models and multimodal AI.Necessary and Sufficient Conditions for Expertise-by-ExperienceIn his initial section titled "Philosophical views on Expert-by-Experience," Sanati examines the literature on Expertise-by-Experience and the recognition it gradually gained as a form of knowledge stemming from the privileged position of subjective experience. Thomasina Borkman (1976), within the context of her research with self-help groups such as Alcoholic Anonymous developed the concept of experiential knowledge. By studying these groups, she saw how some individuals developed valuable skills to help others recover. Borkman (1976), Noorani (2013) and Mazanderani et al. (2020) stress the importance of more than just experience for acquiring expert knowledge. For someone within a community, to emerge as an expert, they must be able to effectively articulate and share the content of their experience, for it to stand a kind of reality testing on its usefulness in guiding and helping other members of it.Ultimately, it appears for the authors cited, Expertise-by-Experience is not conceived on essentialist, a priori theoretical grounds, but on pragmatic outcomes achieved via a constructivist approach. Expertise by experience can't be articulated in context independent propositions. Sanati, in the summary provided at the end of [End Page 109] this section, does not appear to highlight as much this latter formative pragmatic element as a necessary condition for gaining a status of expert-by-experience. He articulates his critique portraying a linear progression from "personal experience" to "unique expertise". In my view, and at least on paper, the claim made for a status of Expertise-by-Experience is a modest one. While it is true, personal experience is acknowledged as a source of a unique type of knowledge, for it to amount to expertise it needs to fulfill the pragmatic test where, by being articulated, shared, tested, and refined accordingly, leads to a know-how relevant to non-experts of the same community. Personal experience as a source of expertise is a necessary condition, but not a sufficient one.Knowledge and Expertise: A Philosophical ViewIn the following sections of the article, Sanati provides an in-depth exploration of the concept of expertise and the philosophical reasoning underpinning his core argument. If we assume Sanati has made a correct interpretation of the cited literature, then a lot of the philosophical analysis provided subsequently assists him convincingly in the task. Collins' (2008) emphasis on the central role of language and discourse in acquiring expertise within a community, and how this leads to a form of life (p. 12), that is also characterized by the possession of a substantial body of true beliefs compared to most people, appears to exclude any possibility for a personal experience on its own to become a source...
