What are the three elements Faber said are missing from a world without books. Was Montag able to recover all of these elements in Fahrenheit 451?

I think what you are talking about is where Faber says the world needs

• Good books -- not just any books, but good ones.


• The time to read them.


• And the right to act on the ideas you get from the first two things.

I don't really think Montag actually recovers any of these because we don't know what happens after the book ends.  Montag has helped to save a good book, and he will probably have the time to read them after the war is over.  But we have no idea what the government and society will turn out like after the war.
