Science is objective, but scientists tend to like things they study; in a notable scene from the 2008 adaptation of Journey to the Center of the Earth, the characters emerge into a cave. One exclaims, “Diamonds!” another “Emeralds!” And then Trevor the geologist (played by Brendan Fraser) remarks, “Feldspar!” It’s natural for geologists to delight in rocks, and it’s natural for linguists to delight in languages.
