Since its publication last April, the latest work of the Lebanese Nassim Nicolas Taleb, The Black Swan, witnessed a spectacular worldwide success. Appearing in the category of «with ideas» and considered as a «non-vulgarized essay with a thousand references», this book on «the impact of the great improbability» and incertitude comes at the head of best-sellers of the New York Times, for the thirteenth consecutive week. It is classified number one of the Business Week and selected among the best books for the year 2007 by Amazon.com. The philosophical approach of the topics with humoristic connotations has yielded interest at all levels: journalistic, academic, philosophical, scientific, political, economic and financial. The Black Swan comes down like an enormous slab stone provoking large scale reverberations. Shall it be perceived in the next Pullitzer Prize Pulitzer?
