... knowledge must continually be renewed by ceaseless effort, if it is not to be lost. It resembles a statue of marble which stands in the desert and is continually threatened with burial by the shifting sand.

Out of My Later Years: The Scientist, Philosopher, and Man Portrayed Through His Own Words, p.26, Open Road Media
