LSAT-0106-2-11

11.   Some psychologists claim that, in theory, the best way to understand another person would be through deep empathy, whereby one would gain a direct and complete grasp of that person’s motivations. But suppose they are right; then there would be no way at all to achieve understanding, since it is psychologically impossible to gain a direct and complete grasp of another person’s motivations. But obviously one can understand other people; thus these psychologists are wrong.

The argument is most vulnerable to the criticism that it

(A) fails to adequately define the key phrase “deep empathy”

(B) assumes something that it later denies, resulting in a contradiction

(C) confuses a theoretically best way of accomplishing something with the only way of accomplishing it

(D) accepts a claim on mere authority, without requiring sufficient justification

(E) fails to consider that other psychologists may disagree with the psychologists cited

理不清这题的思路, 请nn指点.

the answer is wrong . it should be C.

this is a mistake of sufficient condition with necessay condition.

the theory :   if gain a direct and complete grasp of motivation, then, understand others. (sufficient condition)

the critic:  no way to gain such a grasp will lead no way to understand others. (necessary condition)

clear ?

thanks hedonism, i got it.

The Best way: A ==> B

Critic say: ~A ==> ~B

But there are other ways to induce B.
