TITLE: Best book ever on Galois theory (and differential galois theory)
QUESTION [7 upvotes]: Which is the single best book for Galois theory (that includes differential Galois theory) 
that everyone who loves pure Mathematics should read?

REPLY [6 votes]: I always am a fan of Dummit and Foote's Abstract Algebra. I also would recommend Ian Stewart's Galois Theory. Another book you could try is David A Cox's Galois Theory. All of these books are more from the algebra side of things and would not have much to say about differential Galois theory. 
I speak for myself here, but I am not sure there is a book that covers Galois theory from both an algebraic and a differential equations standpoint all within the same cover. The two topics are distinct enough that texts on them are usually separate (At least from what I have observed).
