The Lost Symbol is the 3rd book in the Robert Langdon series by Dan Brown. These books get a lot of rap, but I think they’re fun. So what if they’re not literary masterpieces?
This one takes place in Washington, D.C. I got really excited about that, just like I got excited when I learned National Treasure 2: Book of Secrets was taking place in the U.S.
Anyway, Robert Langdon is contacted by an old friend and mentor to attend a lecture in the capitol city. But when he arrives at the Capitol Building, he discovers he’s been lured under false pretenses. Someone thinks Langdon is the key to unlocking the secrets of the Freemasons, so he’s basically blackmailed into performing a series of tasks to prevent innocent people from dying.
Joining him on his mission to unlock Freemason secrets is Katherine Solomon—a noetic scientist and sister of the Freemason Peter Solomon. Peter is the man who disappeared at the hands of whoever is making Langdon reveal the society’s secrets. With Katherine’s help, Langdon just may be on the verge of exposing the largest enigma known to mankind.
I thought The Lost Symbol was incredibly fun. Every chapter unlocks a new door, taking us deeper and deeper into the mysteries of the Freemasons. Also, I love the concept of noetics, which is very intriguing. Noetics is the science of pure thought and reasoning.
There’s no doubt Dan Brown makes you think outside of the box. It’s interesting how positive thinking has the potential to shift energy. Isn’t that considered common knowledge these days? Maybe it wasn’t when The Lost Symbol came out, but now it is. Right?
There’s a common theme in these Robert Langdon books. Sometimes, treasure is a metaphor, and not a physical entity. Langdon lectures to his students, saying, “Wide acceptance of an idea is not proof of its validity.” Cool, so where the hell was he during COVID when all those debates about masks and other nonsense were going on?
Funny side story about Dan Brown. I once knew a guy who said he was best friends with the REAL Dan Brown, who lived as a recluse in the Colorado Rocky Mountains and smoked cigarettes and wore black all the time. He said this “real” Dan Brown was persuaded into signing over the rights for The Da Vinci Code, and that an actor was hired to be the real Dan Brown. I think about that stupid story every time I see Dan Brown’s name.
The books that come after The Lost Symbol in this series are:
- #4 – Inferno (2013)
- #5 – Origin (2017)
- #6 – The Secret of Secrets (2025)
What did you think about The Lost Symbol? What about Dan Brown, in general? I’d honestly be interested and open to hearing anything you say, good or bad.
