Thus I rediscovered what writers have always known (and have told us again and again): books always speak of other books, and every story tells a story that has already been told.

We stopped to browse in the cases, and now that William - with his new glasses on his nose - could linger and read the books, at every title he discovered he let out exclamations of happiness, either because he knew the work, or because he had been seeking it for a long time, or finally because he had never heard it mentioned and was highly excited and titillated. In short, for him every book was like a fabulous animal that he was meeting in a strange land.

The court jester had the right to say the most outrageous things to the king. Everything was permitted during carnival, even the songs that the Roman legionnaires would sing, calling Julius Caesar "queen", alluding, in a very transparent way, to his real, or presumed, homosexual escapades.

I'm always fascinated by losers. Also, in my "Foucault's Pendulum," the main characters, who are in a way losers, they are more interesting than the winners.

Every time that I write a novel I am convinced for at least two years that it is the last one, because a novel is like a child. It takes two years after its birth. You have to take care of it. It starts walking, and then speaking.

Certainly, light fiction exists and encompasses mysteries or second-class romance novels, books that are read on the beach, whose only aim is to entertain. These books are not concerned with style or creativity - instead they are successful because they are repetitive and follow a template that readers enjoy.

There are more people than you think who want to have a challenging experience, in which they are obliged to reflect about the past.
