What is the Critique of Pure Reason by Immanuel Kant?

Published in 1781 by the German philosopher Immanuel Kant, the Critique of Pure Reason is a foundational work in modern Western philosophy. In this text, Kant introduces transcendental idealism, arguing that space and time are forms of human intuition structuring all experience. He proposes a Copernican revolution where objects conform to our cognitive faculties rather than the mind conforming to objects.
