X+Y: A Mathematician's Manifesto For Rethinking Gender

"I get it: A book that tears down gender constructs through high-level math doesn’t necessarily sound like a fun, engaging read. But this book changed my life in the most beautiful way. Eugenia Cheng doesn’t just explain why the way our society conceptualizes gender is all wrong – she proposes a new way of thinking about – and beyond – gender. Through accessible graphs and brilliant metaphor, Cheng pushes her readers instead to think about a person’s behavior. For example, is an action “ingressive,” single-track thinking or “congressive,” focused on the collective good? With plenty of references to relevant literature, Cheng gives readers the sense they’ve been in an in-depth conversation with her. Stunning."
