Micro-macro relationships

In science when we often encounter processes of thought in which micro and macro relationships are distinguished and analyzed separately. Micro- and macroevolution as well as micro- and macroeconomics may serve as an example.

The rational is the inevitable realization that principles of evolution are untransferable between such entities. Still what is micro and what id macro remains dubious in these concepts. Also, on one hand, the principles applied to macro environment may differ among studies. They may differ even more than among micro and macro themselves.

Anyway, the attempts to distinguish micro and macro processes can be epistemological understood as harbinger of fauceir theory. The micro/macro concept already buys the nested structure of fauceir hierarchies. From there it seems it is only a minor step further to accept a general nested structure.
