Alex Byrne (philosopher)

Alex Byrne is a philosopher. He is Laurance S. Rockefeller Professor of Philosophy at the Massachusetts Institute of Technology.[1]

In 2014, he was awarded a Senior Fellowship of the Zukunftskollegs at the University of Konstanz.[2]

Writing

Byrne has published several controversial essays on transgender rights, including one where he denied that trans women are women and concluded that women were "adult human females", a term used by anti-trans activists to exclude trans women from the definition of "woman".[3][4][5][6]

In 2023, Byrne authored the book, Trouble with Gender: Sex Facts, Gender Fictions which is critical of transgender rights. The original publisher, Oxford University Press (OUP) backed out of publishing the book after reading the manuscript, claiming Byrne did not address the subject of gender in "a sufficiently serious or respectful way." The book instead got published by Polity Press.[7]

On June 26, 2025, Byrne wrote an opinion article in The Washington Post claiming to be one of the authors of the Trump administration's report on gender-affirming care for minors. The HHS did not identify the authors in the report itself and in his article, Byrne did not identify any of the eight other authors he said were involved.[8][3]
