Janusz Rybakowski: 120 years of the Kraepelinian dichotomy of "endogenous psychoses" in historical perspective
Hans-Juergen Möller’s comment on collating document
Thank you for this stimulating discussion on a very high academic level!
I followed with greatest interest all the contributions and all the important pro and con arguments.
The essay written by Prof. Janusz Rybakowski, as well as his further well-balanced statements, seem to me altogether an especially good summary of our current state of the art in this field. It is also a wise condensation of the different other statements, bringing them into a global overall picture which seems to be an adequate theoretical mirror of the meaning of all the empirical findings.
In comparison to my review paper from 2008 on this issue, written in a time when there was strong opposition to the Kraepelinian dichotomy by many famous scientists, especially from the genetic field, apparently the situation has changed and a more pragmatic view willing to compromise seems to have grown. I find this adequate in light of the more recent findings which Janusz has reviewed in his essay so nicely and the additional data and aspects he presented in his recent comments.
Of course, many colleagues will find it disappointing that we can not present a final conclusion in the one or other direction, but we have to accept the complexity of this field. It’s the question of whether new methodological approaches can overcome the inherent dilemmas. I expressed this view in two more or less recent (2015a,b) publications shown below.
