Study Exercises

  1. Find a recent newspaper or magazine article on any health-related topic. Assess the quality of the information in the article based on the criteria discussed in this chapter.
  2. Summarize the key arguments made by the prosecution or the defence in a criminal trial (real or fictional). Try to translate the arguments into either categorical or propositional logic and then assess their validity. See if you can find any examples of either side using inference to the best explanation. If so, indicate what fact the inference tries to explain and how successful the explanation is.
  3. Develop an ethical argument drawn from any of the theoretical approaches treated in this chapter. Include a theoretical and descriptive premise and an ethical conclusion. Is the argument valid? If not, explain why and try to revise it so that it is valid, if possible. How acceptable are its premises?
