Critique of Pure Reason (1787 edition)

"The Critique of Pure Reason," by Immanuel Kant, explores how we understand knowledge and reality. Kant argues that our experiences are shaped by both the external world and our mind's innate structures. He differentiates between "a priori" knowledge (independent of experience) and "a posteriori" knowledge (based on experience). Kant contends that while we can know things as they appear to us (phenomena), we cannot access things as they are in themselves (noumena). This work established the foundation for modern philosophy by addressing the limits of human understanding and the relationship between perception and reality.
