“Critique of Pure Reason” is a work that each generation interprets in its own way, yet remains important for more than two centuries. This book has been a subject of study and interpretation for all major philosophers after Kant, and it continues to attract researchers, writers, moralists, and politicians. It is Kant’s main work, which he contemplated for ten years but wrote in just a few months. It is carefully structured and flawless in form, devoted to questions that have troubled great minds since ancient times—where does knowledge come from, what are its limits, and what roles do feelings, understanding, and reason play in the process of knowing the world.
