<p>Lets not make this a Da Vinci Code argument. Great book, but in my opinion, more controversal than influencial. </p>
<p>
Oh yeah, psh, like I can do that. I agree with a lot of the books posted though. </p>
<p>Uh, I tend to take a more historical slant onto it and tend to think of books like the Communist Manifesto and *Mein Kamf<a href="Which%20I%20can't%20believe%20took%20so%20long%20lol">/i</a>. So common novels to me seem obsolete, but that doesn't mean that they don't deserve a place. </p>
<p>I'm not sure if some of these are mentioned, but I'd add Don Quixote by Miguel de Cervantes, Mathematical Principles of Natural Philosophy by Newton, and Vindication of the Rights of Woman by Mary Wollstonecraft possibly a few more, but I don't remember them at the moment. </p>
<p>Keep going, and if anyone dare try to put them in some sort of order, best of luck to you :p!</p>
