Alexander Baumgarten (1714-1762), an influential German philosopher preceding Immanuel Kant, is remembered mainly as a founder of modern aesthetics. Yet his manual on metaphysics was one of the chief textbooks of philosophical instruction in latter 18th-Century Germany. Originally published in Latin, Kant used the Metaphysics for nearly four decades as the basis for lectures on metaphysics, anthropology and religion. Kant composed many of the preparatory sketches for the Critique of Pure Reason in the blank interleaved pages of his personal copy. Available for the first time in English, this critical translation draws from the original seven Latin editions and Georg Friedrich Meier’s 18th-century German translation. Together with a historical and philosophical introduction, extensive glossaries and notes, the text is supported by translations of Kant’s elucidations and notes, Eberhard’s insertions in the 1783 German edition and texts from the writings of Meier and Wolff. For scholars of Kant, the German Enlightenment and the history of metaphysics, Alexander Baumgarten’s Metaphysics is an essential, authoritative resource to a significant philosophical text.
