Marc-you should have been well pleased by the inclusion of #29 on the list.  Every list is subjective, but that is what makes for some good "discussion."

  I would argue that the wrong Marx book was added as #30. 
 The Wealth of Nations is head and shoulders above either one of those works, as history has proven hands down, but I digress.  
What other works do you feel should have been included?
		
 
		
	 
There is subjective and subjective ;  about 80% of the list consists in english books, the rest being mostly classics from the Antiquity. How can someone believe that such a patently overblown proportion can be representative of the 
humanity's  literary heritage? To me, this list is nothing more then a reminiscence from a strong imperialistic past ; how else could I explain the ostentatious absence of writers such as  Molière, Hugo, Balzac, Baudelaire, Montaigne, Rimbaud, Zola, Proust, Voltaire etc etc. ( I am only speaking for french literature as it is the only one that i know well enough to take a stand for) 
I'm am not even glad about Rousseau if you ask me 

 His 
Confessions, and even his 
Rêveries were far more groundbreaking then the 
Social contract ; the first is often mentioned as being the first modern autobiography, and it is a pleasure to read tant pour des raisons sociologiques que littéraires et philosophiques. Also, why the 
Social Contract and not the 
Emile? The latter one has also had a lasting influence in children pedagogy...  
I am not going to elaborate for every addition that I would make to the list, as this post has already taken a lot of my time, but a palmarès without Baudelaire's 
Fleurs du mal , Montaigne's 
Essays, Laclos 
Liaisons dangereuses  (?), and nothing from the authors mentionned above could hardly pretend to be complete to me (especially when it lacks Balzac!)
