Input (English): This book's universality was attacked by Heidegger in the Davos debate, and its so-called "principle of significance" was attacked in Peter Strawson's The Bounds of Sense. This book compares logic to a courtyard in its B-preface, written six years after its A-preface. It says that we comprehend a "manifold" of sense-data via the "unity of apperception," and claims that space and time exist as "forms of intuition" in our heads. Its author simplified its four sets of contradictory "antinomies," and its split between phenomena and imperceptible noumena, for his Prolegomena to Any Future Metaphysics. This book's transcendental deductions show that "7 + 5 = 12" is within the title mental faculty. For 10 points, name this book which showed that synthetic a priori truths exist, by Immanuel Kant.
