An explanation is an answer to why-question as a description is an answer to
how-question. In the beginning of 20 century, a few philosophers of science,
and philosophers of history too, believed that all scientists (and historians)
must similarly explain the phenomena and (historical) events. D-N Model
and I-S Model have been introduced by philosophers and scientists during
the four decade discussions. Moreover, the positivistic approach maintains
that the explanations preserve the objectivity. Some philosophers, in
contrast, argue that the early definition of objectivity isn't exact and rigorous.
It is, here, claimed that Popper's view in which the objectivity is not a single
scientist's work but the critical debates and cooperative competitions among
the scientists and philosophers, is the best proposal.
