The Mathematician Who Doubted Everything Including Math

[00:00:00]Did you know that three dreams changed the entire course of human thought? René Descartes was 23 years old, Europe's brightest mathematician. Then one night in 1619, he had three vivid dreams that shattered everything he believed.

[00:00:12]Sitting alone by a stove in Germany, he made a radical decision. He would doubt everything, mathematics, science, religion, every single thing he had ever learned. Most people build their lives on assumptions. Descartes tore his down to the foundation, but in that destruction he found something unshakeable. The one thing he couldn't doubt was that he was doubting. I think, therefore I am.

[00:00:32]From that single certainty, he rebuilt human knowledge from scratch. His method became the foundation of modern science.

[00:00:38]The church was so threatened they forced him to delay publishing for years, but his courage launched the Enlightenment.

[00:00:44]Here's what Descartes understood that most people miss. The strongest foundation isn't built on what you refuse to question. It's built on what survives your questioning. True wisdom doesn't come from defending your beliefs, it comes from [music] having the courage to doubt them.
