To speak of "detachment" in regard to nostalgia may seem counterintuitive, since it is our own autobiographical memories that we are dealing with, but it is precisely the lack of such detachment that can take a potentially pleasant memory experience and turn it into the sort of pathologically unpleasant state of mind to which the term "nostalgia" presumably referred when it was first coined.
后面这句定语从句是对detachment的限定,包括and turn it into the sort of pathologically,也是对detachment的限定?
但是这个 turn it into the sort of pathologically 这句话里面的 it 指的哪一个啊?
