Idealization and Deviation

Compared to this polemics: one knows what one is against, and that is enough, the science-specific scheme of idealization and deviation has a lot going for it.

But it is noticeable that this is also a distinction like that of Ethics and Scandal or that of Local and Global or of Orthodox and Opponents.

With a little more distance one can therefore ask: why is the one and not the other distinction preferred? If it is not possible without distinctions, because without distinctions nothing can be observed at all: what speaks for the choice of a certain distinction?
