Behind the great change of ideas and behaviors, is the deeper change of thethinking ways. That reveals as the following: the change from plain experience andthinking in short of empirical facts to positivistic empirical thinking with"hypothesis-test" as basic procedure, the surpassing of the antithesis between twoextremes with the thinking principle of continuity, the surpassing of the linearthinking ways with the systematic thinking ways, the supplement of the ideas aboutthe interactions within the steady system with the ideas of dynamic emergence.
