Immanuel Kant is a critique of pure reason. A gift book in a leather cover. The Critique of Pure Reason is Immanuel Kant's main work. A book that the great German worked on for a decade and wrote in just a month. The book is a goal: the "Critique" postulates his main ideas. German classical philosophy and modern philosophy exist largely thanks to this book. Kant dissects the most difficult and exciting questions and concepts for humanity: what is the mind, what are the boundaries of human knowledge, how we see and perceive the world around us, how the world really differs from the world in our perception. For more than two centuries, this fundamental, carefully thought out and systematized work has been studied by students and philosophers all over the world.
