DL_What Demazeux say? 4/9
To Demazeux, logical-positivist current of DSM is already outdated. The DSM built an artificial language on these premises, a language not referred to the issue of reference but defined criteria that made possible to eliminate the vagueness and misunderstanding.
This Meccano has gone hand in hand with statistics techniques to ensure "inter-judges reliability." But statistics do not escape techniques theory being also in a certain theoretical corpus. And it was silencing the clinical question to give a more prominent statistical question.
However, the crisis of DSM5, starting by disagreement among experts DSM, refers to a deeper than the actual statistical issue is the increasingly clear no relationship between the definition of the category and its reference.
The validity of the DSM was then questioned and has no other system to make greater empiricism. Either that or go to Quine with its logical inputs that allow guest host on natural species and others that are not.
That is would be to accept, as a possible solution that the DSM system had categories of scientific validity and others that were artifacts. Would then remove the hypothesis that it is not enough that a well-made classification itself does not guarantee that the reference diagnosis to be diagnosed.
