An engaging look at the aphorism, the shortest literary form, across time, languages, and cultures  Aphorisms — or short philosophical sayings — appear everywhere, from Confucius to Twitter, the Buddha to the Bible, Heraclitus to Nietzsche. Yet despite this ubiquity, the aphorism is the least studied literary form. What are its origins? How did it develop? Were the enigmatic sayings of charismatic sages the original 'social media'? And why do some of our most celebrated modern philosophers use aphoristic fragments to convey their deepest ideas? In A Theory of the Aphorism, Andrew Hui crisscrosses histories and cultures to answer these questions and more.  Encompassing literature, philology, and philosophy, A Theory of the Aphorism invites us to reflect anew on the meaning of this pithiest of literary forms. 'The history [Hui] has written is devoted to something more like what we usually call 'sayings'...Buy the premise and you'll enjoy the bit, as David Letterman, an aphorist of sorts himself, used to say.' — Adam Gopnik, New Yorker 'This book is groundbreaking.' — Nigel Warburton, Five Books 'Deeply informative and extremely lucid...Its ideal reader might have been Walter Benjamin.' — Lachlan Mackinnon, Times Literary Supplement 'Fans of dense brevity will appreciate that A Theory of the Aphorism is packed tight as a walnut...It is replete with small things.' — Willis Goth Regier, World Literature Today 'Irresistible...Lovers of aphorisms will derive huge pleasure from this elegant and informative book.' — Paradigm Explorer
