The Quest for Absolute Certainty
What if everything you believe is wrong? What if your senses deceive you, your memories lie, and even mathematical truths are illusions? This unsettling possibility launches Rene Descartes' philosophical masterpiece "Meditations on First Philosophy." Written in 1641 amid Europe's scientific revolution, this slim volume represents one of history's most radical intellectual experiments. Descartes doesn't merely question specific beliefs - he systematically doubts everything, seeking a foundation of knowledge so certain that nothing could possibly undermine it. His journey from doubt to certainty revolutionized Western thought, establishing the framework for modern philosophy and science. Imagine waking up one morning and deciding to question absolutely everything you believe. Not just controversial opinions, but basic facts you've always taken for granted - that you have a body, that the world around you exists, even that 2+2=4. This is precisely Descartes' starting point. "I will suppose," he writes, "that everything I see is false." Why adopt such an extreme position? Because Descartes seeks absolute certainty - knowledge that cannot possibly be doubted. He begins by questioning sensory experience. Our senses sometimes deceive us - objects appear smaller at a distance, straight sticks look bent in water. If our senses occasionally mislead us, how can we trust them completely? But the doubt goes deeper. How can you be certain you're not dreaming right now? Even mathematical truths aren't safe. What if, Descartes suggests, an all-powerful evil demon is systematically deceiving you about everything, including basic arithmetic? This method isn't mere philosophical game-playing. By clearing away all assumptions, Descartes prepares the ground for building knowledge anew.
