But now suppose that the economist goes on to argue that, therefore, it would be silly to give patients penicillin, because we know that 98% of all treatable diseases were cured by tradicines, and penicillin is not a tradicine. That is a wrong deduction, based on evidence that does not exist.
但再假设这位经济学家继续指出，因此，给病人使用盘尼西林是愚蠢的，因为我们知道98%的可治疗疾病是通过传统药物治愈的，而盘尼西林不属于传统药物。这是错误的演绎，它的基础是子虚乌有的证据。这位1930年的经济学家的研究表明了传统药物在98%的被治愈疾病中起了作用。它并没有标明盘尼西林起不了作用。
