There are two kinds of dogma's. The religious kind and scientific
kind. The later are ''caused'' by Kant with his ''absolute truth''.
However according to Popper all theories are refutable. In our
case there are two ''concepts'' which are questioned: rigidity and
energy transfer. I am dogmatic in the sense that I would never
use rubber ring between the headshell and the armwand while
both sides assume a coupling between them which can't be tighten
''to mach''.
