Plot hole?
I can't remember if this has been explained elsewhere. Kill me if it has.
I've seen this movie at least 10 times over the years and always loved it completely and thought of it as perfect, if not for a single puzzling thing that might be a huge plot hole... if Jorge is so afraid of Aristotle's second book of poetics, why didn't he burn it instead of poisoning the pages? Surely, hiding this book means enough for him to kill people, so it can't just be sentimental reasons that keeps him from destroying it completely.
And also...
Opposite "Tragedy" which is covered in the real historical first book of poetics, which is a model for telling stories through bad examples, "Comedy" in ancient Greece, and particularly to Aristotle was not an intrument of satire, but a type of story structure that sets a good moral example. Had Aristotle ever gotten around to writing this book, it would most likely have contained nothing about laughing at the gods, but rather contained a guide to writing stories about brave heroes.
