People experiencing mental distress and illness are frequently on the receiving end of stigma, epistemic injustice, and social isolation. A range of strategies are required to alleviate the subsequent marginalisation. We ran a series ‘philosophy of mind’ workshops, in partnership with a third-sector mental health organisation with the aim of using philosophical techniques to challenge mental health stigma and build resources for self-understanding and advocacy. Participants were those with lived experience of mental distress, or unusual beliefs and experiences; mental health (...) advocates; and mental health service providers. We draw on a shared perspective as a participant and facilitator of the workshop series to assess their impact. We discuss the following benefits: the opportunity for structured discussion of experiences and models; dialogue across different mental health backgrounds; the potential to reduce self-stigma and to increase self-understanding and advocacy; and the potential to alleviate epistemic injustice. We invite researchers and mental health practitioners to consider further opportunities to investigate the potential benefits of philosophy groups in mental health settings to establish whether they generalise.
