“When a question has no correct answer, there is only one honest response.The gray area between yes and no.Silence.”

“Mr. Langdon all questions were once spiritual. Since the beginning of time spirituality and religion have been called on to fill in the gaps that science did not understand. The rising and setting of the sun was once attributed to Helios and a flaming chariot. Earthquakes and tidal waves were the wrath of Poseidon. Science has now proven those gods to be false idols. Soon all gods will be proven to be false idols. Science has now provided answers to almost every question man can ask. There are only a few questions left and they are the esoteric ones. Where do we come from What are we doing here? What is the meaning of life and the universe? ”

“maybe the questions are more powerful than the answers.”

“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.”

“When multiple explanations exist, the simplest is usually correct.”

“When his brain died, all of the memoriesheld in his gray matter, along with all of the knowledge he had acquired, would simply evaporatein a flood of chemical reactions.”

“One could argue that there exist certain questions that are best left unanswered.”
