 Baumgarten’s philosophical works cover a wide range of topics. The 1000 sections of his Metaphysica of 1739 offers a synopsis of his views, following the Wolffian division, on ontology, cosmology, empirical and rational psychology, and natural theology. He also published two influential textbooks on ethics: the Ethica philosophica (Philosophical Ethics) of 1740 and Initia philosophiae practicae primae (Elements of First Practical Philosophy), both of which Kant also regularly used in his lectures on moral philosophy. Baumgarten’s abiding interest in aesthetics issued in two texts, the first a dissertation entitled Meditationes philosophicae de nonnullis ad poema pertinentibus (Reflections on Poetry) in 1735, and the second the ambitious Aesthetica, the first volume of which appeared in 1750, with a second unfinished volume printed (at the request of the publisher) in 1758.
