The Second Book of the Poetics

This is the rarest category in the catalogue and the one worth watching for: a fictional book that fills a real hole. Aristotle did promise a second book on comedy. It is lost. Eco did not invent the absence — he only invented what went missing, which is a much harder and much more elegant trick than inventing a book outright.

It also gives the murder plot a motive that no invented heresy could match. Jorge is not protecting a secret; he is protecting a hierarchy. Comedy inverts things, and the man who can laugh at a demon has stopped being afraid of it. If Aristotle — the authority, the philosopher whose sentences settled arguments for four hundred years — is on record saying laughter is a legitimate subject of philosophy, then the argument is over and the fear economy collapses. That is a genuinely enormous thing to kill for, and Eco makes you believe it.

The poison is the detail that lifts the whole novel. It is not a booby trap laid for intruders. It is a filter. Only someone who reads greedily, licking a finger page after page, absorbs a fatal dose. The book is safe for anyone insufficiently interested in it.

On the readability rating. William reads and translates several passages aloud in the closing chapters — the definition of comedy, the argument about the ridiculous — before Jorge begins eating the pages. It is more text than most fictional books ever give up.
