Ima Masochist desires that if she were in the place of X (a nonmasochist) then she be tortured.
The defective if-then GR would entail this. Properly understood, GR only imposes a consistency condition. It doesn't tell Ima what to do.
Ima Masochist desires that if she were in the place of X (a nonmasochist) then she be tortured.
GR doesn't tell Ima to do anything evil. But Ima could satisfy GR; so GR shows a certain weakness here.
The problem lies in taking GR by itself. GR involves factual understanding, imagination, and desires. Any of these may be flawed and further criticized. We especially need to criticize Ima's self-hatred. Ima needs to understand herself better (including why she has such desires), come to appreciate her self-worth, and experience positive ways of living. If Ima develops a love for herself, then GR could help extend this to love-of-others. So GR may not suffice by itself to show Ima her error; but it may suffice when combined with other factors.
