Although this hidden, thinking self may seem less real than the things he usually perceives with his senses, it actually strikes closer to the essence of what he really is. In the Second Meditation, the Meditator concludes that-even if he can’t trust anything he sees, remembers, feels, or imagines-he knows for sure that he’s thinking, so he can still be certain of his own existence. So he tries to suspend belief in all of them by imagining that he’s dreaming, or that an evil demon is controlling his mind and tricking him into thinking that everything he perceives is real. Then, the First Meditation begins with the Meditator pointing out that many of his childhood beliefs have since turned out to be false, and the same might be true of the other ideas he takes for granted now.

In fact, Descartes was one of the earliest and most influential intellectuals to argue for the sciences to reach the same level of rigor and certainty as mathematics, and his work has left a deep impact on philosophy and science ever since.ĭescartes opens the Meditations with a letter asking for support from France’s leading university, the Sorbonne, and a preface summarizing his arguments. He also concludes that anything he clearly and distinctly understands through the intellect must be true, an idea that has since become the foundation for the modern scientific method. Based on this first principle-“I am a thinking thing”-the Meditator deduces that God and the physical world are real. Next, he famously concludes that he can still be certain of one thing: his own existence. This journey begins when Descartes’s narrator, the Meditator, decides to pretend that nothing he perceives is truly what it appears, prompting him to try “start right again from the foundations” of knowledge.

In Meditations on First Philosophy, arguably the most influential philosophical text of the 17th century, René Descartes takes the reader on an intellectual journey in order to demonstrate how scholars can build a systematic, scientific understanding of the world through rational deduction.
