Immanuel Kant (Gutenberg Index)

Immanuel Kant remade philosophy three times over. In the Critique of Pure Reason, he asked how human reason itself limits what we can know, turning epistemology inside out. In the Critique of Practical Reason, he demanded we act from duty alone, giving modern ethics its foundational principle of universal moral law. In the Critique of Judgment, he explored how beauty and purpose speak to something beyond pure logic. This collection gathers Kant's complete philosophical canon: the three Critiques, the Groundwork of the Metaphysics of Morals, Prolegomena to Any Future Metaphysics, and more. These are not easy texts, but they are indispensable. No other body of work has done more to define the questions Western philosophy asks of itself. This is the essential edition for anyone who wants to engage directly with the mind that shaped modern thought.
