Nassim Nicholas Taleb is an essayist principally concerned with the problems of uncertainty and knowledge. Taleb's interests lie at the intersection of philosophy, mathematics, finance, literature and cognitive science, but he has stayed extremely close to the ground, thanks to an uninterrupted two-decade career as a mathematical trader. Specializing in the risks of unpredicted rare events he held senior trading positions in New York and London, founding a trading firm and risk research laboratory. Taleb is also the author of Fooled by Randomness, The Black Swan: The Impact of the Highly Improbable, and Antifragile: Things That Gain from Disorder (Incerto). His ideas on skeptical empiricism have been covered in hundreds of articles around the world.
