This book offers an analysis of humor, comedy, and laughter as philosophical topics in the 19th Century. It traces the introduction of humor as a new aesthetic category inspired by Laurence Sterneâs "Tristram Shandy" and shows Sterneâs deep influence on German aesthetic theorists of this period. Through differentiating humor from comedy, the book suggests important distinctions within the aesthetic philosophies of G.W.F. Hegel, Karl Solger, and Jean Paul Richter. The book links Kantâs underdeveloped incongruity theory of laughter to Schopenhauerâs more complete account and identifies humorâs place in the pessimistic philosophy of Julius Bahnsen. It considers how caricature functioned at the intersection of politics, aesthetics, and ethics in Karl Rosenkranzâs work, and how Kierkegaard and Nietzsche made humor central not only to their philosophical content but also to its style. The book concludes with an explication of French philosopher Henri Bergsonâs claim that laughter is a response to mechanical inelasticity.
