Dan Brown's best-selling novel, The Lost Symbol," [reveals] part of the history of the secretive brotherhood called the Freemasons. Dan Brown: [The book] raises provocative questions about the beliefs of the man on the dollar bill, about the power of the human mind, about whether people can become gods. George Washington was a Mason, along with 13 other presidents and numerous Supreme Court Justices. Benjamin Franklin published a book about Freemasonry on his own printing press. Nine signers of the Declaration of Independence were Freemasons, including ... John Hancock. The last master Mason to serve as president was Gerald Ford. Freemasons have been accused of everything from murder to devil worship to secretly controlling the U.S. government. Arturo de Hoyos is the grand archivist and grand historian of the supreme council of the Scottish rite and himself a 33rd-degree Mason. Arturo de Hoyos: The father of our country was a Freemason. And historians agree that some principles of Freemasonry became cherished principles of the United States. Dan Brown: America wasn't founded a Christian country. It became a Christian country. Many of the founding fathers were deists. Deists believe that a supreme being created the universe, but that being is impersonal. The Masons celebrate mankind and the power of the human mind. I hear about these experiments that are being done that categorically and scientifically prove that the human mind has power over matter. Noetic science really is the reason this book took me so long to write. Noetic scientists study whether age old ideas like faith healing - ESP, mind over matter - actually have a scientific basis. Another important aspect of Freemasonry is this idea of freedom of religion. The last word of the book is one that will surprise people: hope.
