Summary

Kant's Critique of Pure Reason (1781) is the foundational work of modern philosophy, arguing that experience requires both sensory intuition and pure conceptual categories contributed by the mind.

Core Contribution

Kant argued that knowledge requires a synthesis of sensory intuitions and a priori categories of the understanding (causality, substance, etc.); the world we know is partly constituted by our cognitive faculties — the Copernican revolution in philosophy that made the knower active rather than passive.

Key Spikes & Highlights

Copernican revolution (the mind does not conform to objects; objects conform to the mind's a priori structures)
Twelve categories of understanding (causality, substance, unity, etc. — the pure concepts the mind applies to sensory data)
Antinomies of pure reason (reason generates insoluble contradictions — such as whether the world has a beginning — when it exceeds its proper bounds)
Phenomena vs. noumena (we can know phenomena — appearances — but the thing-in-itself remains forever unknowable)
