The German philosopher Alexander Gottlieb Baumgarten (1714–1762) introduced "aesthetics" as a new science in his Reflections on Poetry (1735) and developed this new part of philosophy in a series of later works, culminating in his unfinished Aesthetics (1750/1758). This volume is the first collection of essays in the English language devoted to Baumgarten's aesthetics. The essays highlight the distinguishing features of Baumgarten's aesthetics, situate it in its historical context, document its reception, and examine its contributions to contemporary philosophy.
