I Think, Therefore I’m Wrong: Descartes and the Birth of Overconfidence is your gloriously sarcastic, brutally honest, and deeply unhinged guide to the man who launched modern philosophy with one anxious thought spiral and never looked back.

René Descartes: French, wealthy, suspicious of everything, and armed with just enough Latin to convince the world that his personal identity crisis was actually a groundbreaking intellectual framework. From doubting the entire universe to claiming God exists because the idea of God felt right, Descartes pioneered a system so elegantly flawed it haunted philosophers for centuries—and now you get to enjoy the wreckage.

In this book, Sophia Blackwell (Kant You Not, Leibniz’s Monads) takes you on a laugh-out-loud demolition tour of:

• The Four-Step Method of Doubt, also known as gaslighting the cosmos
• The Cogito, or how to accidentally make thinking sound smug
• God as epistemological tech support
• Mind-body dualism, or “what if you’re just a haunted skeleton?”
• Descartes’ legacy in science, psychology, AI, and every freshman who says “I'm not my body, bro.”

Whether you’re a philosophy student, a recovering Cartesian, or just here to watch the metaphysical world burn, this book explains Descartes’ ideas the way they were always meant to be understood: with sarcasm, side-eye, and a glass of wine.
