Beyond being an enthralling mystery, Foucault's Pendulum also explores the variations in language and meaning. We have three editors who create a dazzling tale; a tale that stretches though thousands of years of history, full of mystery magic and intrigue. But in reality, the whole thing was based on an random interpretation of events, picked to be clever and by computer, not based necessarily on truth. I think that Eco is seeking to shed light on the notion that we find mysteries all over this world, because mystery satisfies our sense of wonder. Language is mysterious because it is intricate. A single cryptic page can be a shopping list or review of a world wide masterplan.Eco's book is fabulous for its intricacy and its ability to drag the reader down the same path as the editors, a path where the lines between fact and fiction blur.
