The aim of this entry is to provide the reader with a philosophical map of the progression of the concept and experience of boredom throughout the Western tradition—from antiquity to current work in Anglo-American philosophy. By focusing primarily on key philosophical works on boredom, but also often discussing important literary and scientific texts, the entry exposes the reader to the rich history of boredom and illustrates how the different manifestations of boredom—idleness, horror loci, acedia, sloth, mal du siècle, melancholy, ennui, (...) monotony, and emptiness—are grounded in the historical context in which they arise.
