“Coincidence was a concept he did not entirely trust. As someone who had spent his life exploring the hidden interconnectivity of disparate emblems and ideologies, Langdon viewed the world as a web of profoundly intertwined histories and events. The connections may be invisible, he often preached to his symbology classes at Harvard, but they are always there, buried just beneath the surface.”

“I realised that despite the hangups, despite the crazy drama he created, I would love him always. Clay was mine just as surely as I was his. My life and his were inexplicably intertwined and there was no denying the intense connection we shared.”

“The man who views the world at 50 the same as he did at 20 has wasted 30 years of his life.”

“In which year did a Harvard sculler last outrow an Oxford man at Henley?" Langdon had no idea, but he could imagine only one reason the question had been asked. "Surely such a travesty has never occurred.”

“He plunged beneath the surface and knew that these were Elyon's waters, and his lake had no bottom.”

“He is spent. His mind is mercury again, its brief surge of humanity melting into an oily residue on its surface, and he no longer understands the feelings he felt in that strange moment on the overpass.But he did feel them. They did happen. They rest on the murky seabed of his mind, buried under sand and silt and miles of grey waves. Patient seeds waiting for light.”
