Alex Byrne
Professor of philosophy and author
Alex Byrne is a professor of philosophy at MIT whose work scrutinises the conceptual foundations of sex and gender. On Beyond Gender he joined fellow philosopher Moti Gorin to ask what we actually mean when we call a child transgender — and why that question matters urgently for Irish families, schools, and health services.
Alex Byrne is Professor of Philosophy at the Massachusetts Institute of Technology (MIT), where his research spans philosophy of mind, language, and epistemology. In recent years he has brought that analytical rigour to bear on the philosophy of sex and gender, most notably in his book Trouble with Gender, which argues that biological sex is binary and that conflating it with gender identity generates serious conceptual and practical harms — for individuals, for medicine, and for law.
On the Beyond Gender episode What is a Transgender Child? (July 2026), Byrne joined Mia Hughes and fellow philosopher Moti Gorin to probe one of the gender debate's most contested concepts. Central to their discussion was the late Ian Hacking's notion of 'making up people' — the insight that our categories do not merely describe a pre-existing reality but actively shape the identities of those placed within them. Applied to children, this is a significant claim: the label 'transgender child' may itself do considerable work in producing the very identity it purports to identify, with consequences that are difficult to foresee and hard to reverse.
For Irish parents, teachers, and clinicians, this reframes an already urgent question — not simply how to support a gender-questioning child, but what effect the language we reach for may itself have on that child's development. Ireland's recent experience makes Byrne's analysis particularly timely: school social-transition policies, the suspension of paediatric gender services, and ongoing Dáil debate have all advanced with relatively little philosophical scrutiny of the foundational concepts involved. Stella O'Malley, an Irish psychotherapist who has worked with gender-questioning young people throughout these years, brings precisely that scrutiny into the consulting room; Byrne's work gives it its clearest philosophical grounding.
