Hi Pineapple, I think in some ways the two sentences are quite similar but there are certainly differences. For example, "persist" and "insist" are not completely interchangeable but you could definitely argue that "changing Freud's concept of fetishism from inside" is similar to "reworking Freud’s concept of fetishism from within its own terms". I would also say that there is a slight difference between "disagree" and "attempting to transgress its parameters in exuberant play" but they do seem to be used in a similar way here. Hope that helps! Sean :)

persist and insist aren’t really interchangeable, but other than that it more or less means the same thing. The one below has more advanced vocabulary that means slightly different things to the first sentence. However, it doesn’t truly effect the meaning too much. Sorry if I’ve not made sense!
