A police officer of yours once told me that the equation 2 + 2 = 4 is an opinion in some places. Okay, fine. My question to you is, then: In what places is this equation an opinion and in what places is it not? Is 2 + 2 = 4 an opinion in Glen Carbon but not in Ladue, where the Grade School teachers, unlike in Glen Carbon, may actually have to know stuff before they are hired? Is the certainty of basic arithmetic contingent upon astronomical conditions as well as geography? Does 2 + 2 = 4 become an opinion in Glen Carbon only when the moon is full, thereby changing all people with a gun and a badge into howling lunatics?
Inquiring minds really want to know.
