• [今日の素読]
  • Salsburg, D. 2001. `` The Lady Tasting Tea -- How statistics revolutionized science in the twentieth century''. Owl Book.
  • Chapter 18. Does Smoking Cause Cancer?
    • Material implication
  • With some redundancy, Koch was stating the conditions for material implication. This may be adequate to determine that a particular species of bacteria caused the infectious disease. When it comes to something and cancer, however, Koch's postulates are of little value. Let us consider how well the connection between lung cancer and cigarette smoking fits Koch's postulates (and hence Russell's material implication). The agent is a history of cigarette of the lung. There are cigarette smokers who do not get lung cancer. Koch's first postulate is not met. There are some people who get lung cancer who claim that they have not been smokers. If we are to believe their claims, Koch's second postulate is not met. If we restrict the type of cancer to small oat-cell carcinoma, the number of nonsmokers with this disease appears to be zero, so maybe the second postulate has been met. If we take the agent away, that is, if the patient stops smoking, the disease may still come, and Koch's third postulate is not met.
