But for better or for worse, this is a general phenomenon which arises in the explanations of complex systems. In order to acquire an intuitive and manageable understanding of how parts interact --in short, in order to proceed-- one often has to sacrifice the exactness yielded by a microscope, context-free picture, simply because of its unmanageability.

The fluidity of descriptions insures that paradigm shifts will take place on all scales.
