CHAPTER NINE

Enemies at the Gates

BY THE TIME Descartes started sharing pieces of his philosophy, it wasn’t just “a new idea.” It was a threat.

The Church didn’t like the idea of people throwing out tradition and starting over. Other philosophers didn’t like the idea of some math guy tearing down centuries of thought with a few pages of Latin. Even his friends started getting nervous.

And Descartes? He kept going.

He didn’t like drama, but he wasn’t afraid of it either. He just didn’t see the point in getting dragged into other people’s fights. While the academic world started picking sides over what he’d written, Descartes moved to the Dutch Republic. Partly because it was more tolerant, partly because he liked working in peace.

He stayed mostly off the radar. He avoided universities. He didn’t take students. He preferred writing and thinking on his own. He once said he wanted to live “as quietly and as privately as possible.” That was his style. Not hiding, just staying focused.

But he couldn’t stay invisible forever.

In 1637, he published Discourse on the Method. That was his first big move. It was written in French, not Latin, which meant regular people could actually read it. And that alone was enough to raise eyebrows. Inside, he explained his four-step method, broke down some of his physics and optics theories, and dropped the line that would define him forever: Cogito, ergo sum.

The response was mixed.

Some people were blown away. Others were furious. The Catholic Church wasn’t thrilled, especially because Descartes’ method didn’t leave much room for divine revelation. If truth had to be earned through reason alone, then what was the point of faith?

At the same time, scientists who were loyal to Aristotle thought he was being reckless. They didn’t like that he was tossing out their entire framework like it was a bad habit. They called him arrogant. Unstable. Dangerous.

And then there were the critics who just didn’t understand what he was doing. Which, honestly, was most of them.

Still, Descartes kept writing. He kept refining. He had no interest in being part of a school or a movement. He didn’t want disciples. He wanted accuracy.

His biggest fear wasn’t being wrong, it was being misunderstood.

But that was already happening.

His enemies were growing. His inbox was getting louder. And his ideas were about to get even stranger.
