Alexander Gottlieb Baumgarten

Alexander Gottlieb Baumgarten, a German author, born in Berlin in 1714, died in Frank-fort-on-the-Oder, where he was professor of philosophy, May 26, 1762. He was the founder of the science of aesthetics in his two works: De Nonnullis ad Poema pertinentibus (Halle, 1735), and AEsthetica (2 vols., Frankfort, 1750- '58, incomplete), which are written in the spirit of the Wolfian philosophy. Baumgarten was the first to attempt a scientific analysis of the principles of beauty in nature as well as in art, and of those faculties of the mind by which the beautiful is recognized. He maintained that the mind has a double faculty of perception, the higher or logical one, which forms reasonable notions establishing the truth, while the lower or aesthetic perceives immediately, without conscious reasoning, the elements of beauty. Other works of Baumgarten are Metaphysica, Ethica Philosophica, and Initia Philosophies Practice.
