"[H]e bewailed her Loss with Groans, which would have pierced any Heart but those which are possessed by some People, and are made of a certain Composition not unlike Flint in its Hardness and other Properties; for you may strike Fire from them which will dart through the Eyes, but they can never distil one Drop of Water the same way."
— Fielding, Henry (1707-1754)
