Dan Brown creates a intensifying thriller that keeps the reader on the edge of his seat and the constantly changing character development keeps the reader from putting down the book, however, Dan Brown hides a deeper message that he believes the world should address: overpopulation. The novel's antagonist Bertrand Zobrist a multi- billionaire genetic engineer who is apart of the pro- human society called transhumanism. Transhumanism is a class of philosophies of life that seek the acceleration of the evolution of intelligent life beyond its current human form through science. However, Zobrist believes in a mathematical theory called Malthusian Theory. The theory states that the human population will increase past the carrying capacity of the earth ultimately leading to the extinction of the human race and the human race would never be able to reach its full potential. Taking out the fictional bits of information of Zobrist and his radical ideas for change Dan Brown raises an issue that has been ignored in the science community which is the greatly increasing number of us. In the novel Brown uses the main character Langdon to drop in hints to his messages, '"Napoleon had once refereed to St. Marks Square as "the drawing room of Europe ," and the from the looks of things, this "room" was hosting a party for far too many guests . The entire piazza looked almost as if it would sink beneath the weight of its admirers."' Also Langdon suffers from claustrophobia which plays into Dan Browns overall theme of overpopulation and the shrinking space on earth.
