Are we all part of a book?

I've been reading the book Niebla, by Spanish author Miguel de Unamuno. There's a lot of things in the book, but one of the big things in it is that at the end, Miguel de Unamuno enters the book as himself and actually talks with his characters. He admits that he is their author, and then a big metaphysical conversation pops up. The whole shinding ends with Miguel de Unmauno condeming Augusto, the protagonist, to death because he pisses him off.

I guess this raises the question of are we all a part of the book written by a higher power? How do we know?

Maybe we are all part of a book, but rather than God's book, we and everyone we know are a part of our own book. Our actions in life are kind of like us, as the authors, writing the pages of our "book".

Hope that makes sense, but thoughts? BTW This is a large part of what my summer research entails: trying to answer this question.

 

It's basically to show that Miguel de Unamuno, a Spanish philosopher who wrote in the early 20th century, was a precursor to more well known philosophers Jean-Paul Sartre and Albert Camus.

But yeah that's the question here and I wanted to see what other people thought.

 

You hit the ball on the head with your bit about existing in the past. Our actions are what define us, and you explained exactly why.
