scheme What does it mean for a statement to be true? Some statements can be verified directly. To determine whether a particular omelette is delicious, we merely have to taste the omelette. Our answer is imprecise, however. We must wonder: how tasty must a “delicious” omelette be? What egg dishes are properly called “omelettes?” Assuming our taste test succeeds, we can answer the question for only one omelette at a time. We may never know whether all omelettes are delicious, even if each individual omelette we try is tasty.
