Right and if you read it, they argue the same as I do.
Sorry, I meant that 1 sentence from a book is equal to 1 word from English dictionary. Thus we have a password with only 1 (one) "symbol" and entropy equal to number of sentences. More popular sentences have a higher chance to be used, thus if u try all sentences in order according to their Google "citing" index u'll pick a passphrase quite quickly.
