"The skeptics are quite right when they say that the history of humanity is one long succession of missed opportunities. Fortunately, thanks to the inexhaustible generosity of the imagination, we erase faults, fill in lacunae as best we can, forge passages through blind alleys that will remain stubbornly blind, and invent keys to doors that have never even had locks." Jose Saramago, The Elephant's Journey, 2008
