Critique of Pure Reason (Thrift Editions) - Tapa blanda

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.

A central figure of modern philosophy, Immanuel Kant (1724-1804) synthesized rationalism and empiricism, and his thinking continues to influence the fields of metaphysics, epistemology, ethics, political philosophy, and aesthetics. The German philosopher's best-known maxim is a moral law that he called the categorical imperative, which states that morality is derived from rationality and all moral judgments are rationally supported.
