Who wouldn't like a flawless world were there is perfect balance on every aspect of society? Who wouldn't want to live somewhere where everything and everyone is equal, and there is only good and no bad? On everyone's deepest desires this dream falls upon, however it is only dream, nothing more. No thing such thing as perfection exists, it will always remain as an aspiration, but never a reality. Perfection, in any way is something impossible to achieve.
Eldorado seems to be the ideal society: The utopia we've all dreamed of. It is amazing how such place could be found, however it is all but a mere reality, it is nothing more than pure fiction. "We are all of the same opinions here" (Pg. 80) Until the day of today, most of the global issues happening all around the world are caused because of dissenting views. People are always disputing on who is right or wrong. Virtually everything on earth has dissenting views, is it from global warming to the theory of the dinosaurs extinction. It is impossible for everyone to agree of everything, that's just not the way things are and it will never be like that. Moreover, Voltaire exhibits this place as hidden from everything, almost impossible to reach. "The mountains which surround my entire kingdom are then thousand feet high, and as sheer as wall. Each of them covers an area of more than thirty square mils, and when you reach the top, you can only clamber down precipices." (Pg. 83) Which in others words, can be translated to an allegory to the impossible. Such place is impossible to reach, therefore it doesn't exist, it can only exist in our imagination.
Eldorado doesn't exist, and Voltaire clearly knew that. He shows and portrays el Eldorado that way, in order for to his readers to see the perfect, but unattainable society. He exhibits what we must strive for, but through the book demonstrates that we will never achieve that, much less perfection, as our nature doesn't allow us to.
