Rene Descartes

Rene Descartes was a French philosopher, scientist, and mathematician who lived during the late Renaissance and Reformation period. He is best known for his statement "Cogito, ergo sum" or "I think, therefore I am," which emphasized the importance of doubt and questioning in gaining true knowledge. During his time, this was important because it challenged traditional views and encouraged a scientific approach to understanding the world. Descartes' emphasis on reason and evidence laid the groundwork for modern scientific methods and rational thinking. Today, his legacy is seen in how we approach problems logically, like when a student uses critical thinking to solve a math problem or a scientific experiment in school.
