RamseyGoonerJust in case Bunuel doesn’t come, I’ll give you my thoughts (maybe they will be helpful).
John writes:
(1)
“A great writer does not need any diversity in subject matter.”
IF: a person CAN be considered a great writer —————> THEN: NOT required to have diversity in subject matter
(2)
“However, a great writer must at least have the ability to explore a particular theme deeply.”
IF: a great writer ———> THEN: at the very least, that person must have the ability to explore a theme deeply.
(C)”if Favilia has explored some particular theme deeply in her writings, she DESERVES to be considered a great writer.”
What’s given in the 2nd mapped statement in the “IF-THEN” conditionals above is just one pre-requirement for a person to be considered a great writer.
The formal logical fallacy made in (C), with respect to the (2nd) mapped statement above, is given the nickname of the “mistaken reversal.”
Just because one of the pre-conditions is met to be considered a great writer, this does not necessarily mean the person IS (“deserves to be called”) a great writer.
There may be many other pre-requirements in John’s mind beyond having the ability to explore deep subject matter. Just because one pre-requirement is met, does not ensure that the person can be considered a great writer.
(In formal “logic speak” - affirming the necessary condition does not ensure that he sufficient condition will occur)
C is not a position that John is committed to.
(A)”Even if the subject matter in Favilia’s writings is not particularly varied, she should NOT be Excluded from being considered a great writer.”
This is essentially what John’s argument is.
The argument he responds to is saying:
Since F.’s subject matter is not varied enough, then F. can NOT be considered a great writer.
Answer choice (A) is not saying that if the subject matter is varied, then the author MUST be considered a great writer.
Rather, answer (A) says that we should not exclude F. from being considered a great writer (in other words, F. is ELIGIBLE to be considered a great writer) even though the subject matter might not be varied enough.
This is essentially the position that John takes when he argues against the original author.
A is the correct answer.
Mapping the logic out definitely helps, but it is also helpful to sometimes step back and just think about each person’s position.
Another good thing to look out for: the modifier words used.
Saying that someone is “not excluded” from A ———> is not exactly the same claim as saying that a person IS part of A.
When you say a someone is “not excluded”, you are not giving your position on whether the person definitely is “included.”
I hope that didn’t hurt your head as much as it did mine…..
Sometimes the LSAT is just not fun.
