Descartes doubts everything

Philosophy · Europe · Netherlands

Meditations on First Philosophy razed every belief that could be doubted, rebuilding from a single certainty: a thinking self — cogito, ergo sum.

Why it matters

Descartes made the individual mind the foundation of knowledge and split reality into mind and matter — the move modern philosophy has spent four centuries arguing with, from Spinoza to cognitive science.
