> An author just wrote a book. I ask the author what the book is about, and she says, "it's about how anyone, if they work hard enough, can lead a fulfilling life". There's nothing left to talk about; the author explained the meaning and the case is closed.
However, let's ask the author a different question: "in your book, how do you communicate the message that anyone can lead a fulfilling life." And the author responds: "I communicate this message by writing about several characters who, although they all come from different backgrounds, all manage to lead fulfilling lives."
