The Critique of Pure Reason is the first of Immanuel Kant’s three critiques. In it, Kant seeks to establish what human reason is capable of knowing without the senses. Kant argues that while reason is capable of arriving at some truths, it is not capable of comprehensive knowledge. Rather, says Kant, our understanding of reality comes by our mind shaping our sense experience. Our sense of time makes us see the world as temporal. Kant argues that it is impossible to have certain knowledge of a thing “in itself.” We can have accurate knowledge, but it is shaped by our perceiving minds.
