Critique of Pure Reason

A cornerstone of Western philosophy by one of history's most influential thinkers, this treatise seeks to define the nature of reason.

Kant designates two types of knowledge: à posteriori, knowledge gained through experience, and à priori, knowledge gained independent of experience.

He thus builds his own unique system of philosophical thought, known as transcendental idealism, based on meticulous investigations of metaphysics, ethics, and aesthetics.
