"Archeology is the search for fact, not truth. If it's truth you're interested in, Dr. Tyree's philosophy class is right down the hall. [the students laugh] So forget any ideas you've got about lost cities, exotic travel, and digging up the world. We do not follow maps to buried treasure, and X never, ever marks the spot. 70% of all archaeology is done in the library. Researching. Reading. We cannot afford to take mythology at face value."
