The Critique of Pure Reason

"The Critique of Pure Reason" by Immanuel Kant is a philosophical book from the 1700s that asks how much humans can truly understand about the world. It explores if some knowledge comes from what we experience (learning by doing), or if we are born knowing some things (like basic ideas). The book kicks off with the idea of studying how reason works. Humans can know things without having someone show them, and Kant emphasizes that some of our thinking tools let humans make solid conclusions that are not from seeing or touching things, and that before we make big claims, we need to figure out how knowledge works.
