René Descartes is best known for establishing the foundations of modern rationalism and analytical geometry. Operating during the Scientific Revolution, he sought to rebuild human knowledge from the ground up by rejecting reliance on authority and sensory perception, which he deemed deceptive. In his seminal works, such as 'Discourse on the Method' and 'Meditations on First Philosophy,' Descartes introduced the method of radical doubt.
Philosopher · Mathematician
René Descartes (1596–1650) was a French philosopher, mathematician, and scientist, widely regarded as the "Father of Modern Philosophy." Breaking away from the Aristotelian traditions that dominated the medieval era, Descartes championed the use of reason and the scientific method. He famously employed methodological skepticism, stripping away all beliefs that could be doubted to arrive at a single, undeniable truth: Cogito, ergo sum ("I think, therefore I am"). This axiom became the foundation for his dualist metaphysics, which distinguished the immaterial mind from the mechanical body. Beyond philosophy, Descartes revolutionized mathematics by developing the Cartesian coordinate system, which bridged algebra and geometry and paved the way for calculus. His insistence on clear and distinct ideas established the framework for Rationalism, influencing generations of thinkers including Spinoza, Leibniz, and the major figures of the Enlightenment.

Quick answers about Rene Descartes.
Descartes' work serves as the bedrock of the modern scientific method, emphasizing that complex problems must be broken down into simpler, manageable parts. His integration of algebra and geometry created the mathematical language used to map the physical world today.
Apply Cartesian thinking by practicing radical skepticism toward unverified assumptions in your decision-making process. When facing a complex issue, use his method of reductionism to divide the problem into its smallest components and solve them individually.
