Publisher's Description

In recent decades gender identity theory has surged from queer obscurity to mainstream prominence. The basic idea is that “gender” is a personal and performative identity category, and one’s “sex” is defined by one’s gender, not the other way around. Further, this is not just a theory, it is a political and moral imperative. In the cause of justice for the marginal and a diverse and inclusive utopia, we must now discard oppressive and supposedly “objective” commonsense conventions premised on the male/female sex binary. Thus, gender theory, in the form it has now come to be understood, purports to justify the tearing up of sex-defined gender norms and outlaws sex-based rights for women and girls. But where does this theory come from? Is it persuasive? Gender theory is the intellectual progeny of Kant’s Enlightenment. While modern and postmodern philosophy after Kant really is persuasive if one accepts Kant’s purity agenda, by now it is clear that this pathway leads to madness. Purifying science from faith, and purifying reason from metaphysics, leads to the inability to tell the difference between a man and a woman. This book seeks to show the reader why Kant was wrong and why gender theory is wrong.

“A fascinating look at the deep philosophical background to gender theory and the basis of its superficial intellectual appeal. Essential reading for anyone interested in this vital contemporary debate”.”

Kathleen Stock

“Paul Tyson is an authentic lover of wisdom. We are in desperate need of sane and straight-talking philosophers like him because the most basic commonsense realities of human sexuality have now been abandoned by many academic elites. In this book Tyson provides an accessible and illuminating unpacking of why obvious truths about the facts of life have become invisible to our elites. He walks us through the long and surprising story of how we got to this very strange sex and gender fluid place. Then, after making sure we understand what makes gender theory seem credible, he goes on to show why it is wrong. And dangerous. This book is an important read for anyone struggling to understand what gender theory is and why anyone believes it.”

“In this immensely erudite book, Paul Tyson argues for basic common-sense biological sex, without denying the fact that biological sex can be lived out in many ways. His core goal is to persuade policymakers and academics to stop persecuting people who insist on the fact that a man cannot become a woman and vice versa. A society built upon the notion that biological sex is false or at least radically fungible will, indeed, be one that produces far more injustices than were endured by non-sexually-conforming persons in past societies. Tyson provides an ample genealogy for the current academic, cultural, and political understanding of the transgender cause. He identifies roots as far back as Peter Abelard’s and William of Ockham’s nominalism, and continuing on through the anti-realist epistemologies of Kant and his praxis- and will-focused heirs, joined to left-wing Hegelian understandings of the march of history. Nietzsche, Marx, Critical Theory, Postmodernism, and Judith Butler, among many others, play their part here. Calling for a return to rationality grounded in realist metaphysics, Tyson shows that the result could paradoxically assist modern liberalism in being properly liberal.”

“Paul Tyson has the critical academic credentials in the relevant areas of philosophy, theology, sociology, science, and politics to address this challenging area of gender theory. He also writes directly and lucidly. For too long the debate about gender theory has been hampered by obscure and dense verbiage designed to mystify its readers. It leads many to surrender to a range of powers aiming to take away their agency. Tyson clears away the undergrowth to empower those open to his and the great philosophical and scientific realist tradition of a ‘meaningful understanding of natural facts.’ I found light-globes going off regularly as Tyson’s genealogy clearly linked movement to movement, finally opening a door through the dark. Having shown how our ‘knowledge elites’ frolicked along in their performative meaning making games, Tyson takes seriously what they do not—people’s lives, especially young people’s lives—are at stake. He draws on a range of practical and radical arguments to show not only that, but how Gender Theory is wrong. It has taken a Kantian and linguistic wrong turn away from reality. But by ‘recovering a lifeworld without Gender Theory,’ Tyson provides a patch for rebooting the Enlightenment and the natural meaning of sex, in all its goodness and familial importance. As law and medicine, the courts and upholders of the Hippocratic Oath slowly seek to recover some sense of scientific sexual sanity, for the sake of a whole generation, this brilliant and courageous book is well-placed to best help so many sufferers from their seemingly never-ending gender nightmare, to recover a route back to a semblance of reality.”

Gordon Preece

“A tour-de-force through centuries of intellectual thought on sex, gender, and politics, Tyson situates contemporary debates within a long philosophical genealogy, inviting readers to consider how formerly unthinkable ideas about truth, biology, and identity have come to be taken for granted and enshrined in our institutions.”
