The First Meditation

In "The First Meditation," philosopher René Descartes examines the nature of doubt and knowledge. He questions everything he believes to understand what is absolutely certain. Descartes considers that our senses can deceive us, leading him to doubt external reality, the existence of the physical world, and even mathematical truths. He arrives at the famous conclusion, "I think, therefore I am," asserting that the act of thinking is undeniable proof of one’s existence. This meditation sets the foundation for modern skepticism and the quest for certainty in knowledge.
