Even though MacArthur’s diet book helped many people lose weight, MacArthur should not have published it. It recommended such small portions of fruits and vegetables that it undoubtedly damaged the health of many who followed the diet. MacArthur is a physician, so MacArthur either knew or should have known that diets low in fruits and vegetables are unhealthful.
Which of the following principles, if valid, most helps to justify the argument’s reasoning?
  • a)
    One should not undertake an action if one knows that doing so would seriously damage the health of many people.
  • b)
    One should not follow a particular method for achieving some end if doing so has the potential to damage one’s health.
  • c)
    One should publish a book recommending certain health-related measures if doing so is likely to improve many people’s lives without also causing harm.
  • d)
    One should not publish a book recommending a particular means of attaining a goal unless one knows that the particular means can bring about that goal.
  • e)
    One should not publish a book recommending a particular course of action if one either knows or ought to know that taking that course of action would be unhealthful.
Correct answer is option 'E'. Can you explain this answer?
Most Upvoted Answer
Even though MacArthur’s diet book helped many people lose weight...
(A) One should not undertake an action if one knows that doing so would seriously damage the health of many people.
This principle aligns with the argument's reasoning by stating that one should refrain from taking actions that would seriously harm the health of many people. It supports the assertion that MacArthur should not have published the diet book if it caused harm to individuals who followed the diet.
(B) One should not follow a particular method for achieving some end if doing so has the potential to damage one's health.
This principle focuses on individual actions and decisions rather than the publication of the diet book. It doesn't directly support the argument's reasoning regarding MacArthur's responsibility as an author and physician.
(C) One should publish a book recommending certain health-related measures if doing so is likely to improve many people's lives without also causing harm.
This principle opposes the argument's reasoning. It suggests that publishing a book recommending health-related measures is justifiable if it improves many people's lives without causing harm. It doesn't align with the argument's claim that the diet book caused harm due to the recommended low portions of fruits and vegetables.
(D) One should not publish a book recommending a particular means of attaining a goal unless one knows that the particular means can bring about that goal.
This principle doesn't directly support the argument's reasoning. While it discusses the publication of a book recommending a particular means to achieve a goal, it doesn't address the issue of potential harm caused by the recommended means.
(E) One should not publish a book recommending a particular course of action if one either knows or ought to know that taking that course of action would be unhealthful.
This principle strongly justifies the argument's reasoning. It states that one should not publish a book recommending a course of action if one either knows or should know that it would be unhealthful. This principle aligns with the argument's claim that MacArthur, as a physician, should have known that a diet low in fruits and vegetables is unhealthful.
Based on the analysis, option (E) is the most suitable choice as it best justifies the argument's reasoning by emphasizing the responsibility of a physician not to publish a book recommending a course of action that they either know or should know is unhealthful.
