Principle: One should criticize the works or actions of another person only if the criticism will not seriously harm the person criticized and one does so in the hope or expectation of benefiting someone other than oneself.
Application: Jarrett should not have criticized Ostertag’s essay in front of the class, since the defects in it were so obvious that pointing them out benefited no one.
Which one of the following, if true, justifies the above application of the principle?
(A) Jarrett knew that the defects in the essay were so obvious that pointing them out would benefit no one.
(B) Jarrett’s criticism of the essay would have been to Ostertag’s benefit only if Ostertag had been unaware of the defects in the essay at the time.
(C) Jarrett knew that the criticism might antagonize Ostertag.
(D) Jarrett hoped to gain prestige by criticizing Ostertag.
(E) Jarrett did not expect the criticism to be to Ostertag’s benefit.
EXPLANATION FROM POWER PREP
The principle states that one should criticize another person
only if the criticism does not harm the person criticized
and the critic expects to benefit someone other than himself. Since "only if" is a necessary condition indicator, both of these requirements must be met in order for the criticism to be sanctioned.
Criticize :arrow: Criticism does not harm the person criticized AND Critic expects to benefit someone other than himself
Note the distinction between fact and opinion in the two prongs of this principle: the first necessary condition is a matter of fact (no harm done); the second necessary condition is a matter of opinion (the critic
expects to benefit someone else). To trigger the contrapositive, if
either of these two requirements is not met, then one should not criticize the other person.
The application of the principle states that Jarrett
should not have criticized Ostertag. The only reason given is that the defects were so obvious that pointing them out benefitted no one. This has no bearing on whether Jarrett’s criticism is warranted or not. In order to justify the conclusion, we need to show either that Ostertag was seriously harmed by the criticism, or that Jarrett did not expect his criticism to benefit anyone.
Answer choice (A): This is the correct answer choice. If Jarrett knew that the defects were obvious and that pointing them out would benefit no one, he clearly could not have expected that his actions would benefit anyone else. By the contrapositive property of the principle stated above, Jarrett should not have criticized Ostertag’s essay.
Answer choice (B): This answer choice suggests that if Ostertag were aware of the defects in his essay, then Jarrett’s criticism would not have benefitted him. However, we cannot know whether Ostertag had any awareness of these defects. Furthermore, even if he did, it is irrelevant whether anyone
actually benefited from Jarrett’s criticism. What matters is whether Jarred himself
believed that anyone would benefit from the criticism. This answer choice does not provide any information about Jarrett’s beliefs.
Note that the conclusion can also be proven by evidence showing that Ostertag was seriously harmed by Jarrett’s criticism. All we know, however, is that Ostertag
did not benefit from it. This is not enough to show that Ostertag was
seriously harmed by Jarrett’s criticism.
Answer choice (C): Even if Jarrett knew that the criticism might antagonize Ostertag, this does not establish that the criticism would
seriously harm Ostertag and therefore does not prove the conclusion.
Answer choice (D): The hope of gaining prestige is not the same as
believing the criticism would benefit someone other than Jarrett. This answer is therefore irrelevant to the conclusion.
Answer choice (E): It does not matter whether Jarrett did or did not expect his criticism to benefit Ostertag. To prove the conclusion, we must know that Jarrett did not expect to benefit
anyone other than himself. It is entirely possible that Jarrett expected his criticism to benefit other people in the class (just not Ostertag). Therefore, this answer choice does not trigger the contrapositive of the principle and fails to prove the conclusion.
