Hegelian dialectic, usually presented in a threefold manner, was stated by Heinrich Moritz Chalybäus  as comprising three dialectical stages of development: a thesis , giving rise to its reaction, an antithesis , which contradicts or negates the thesis, and the tension between the two being resolved by means of a synthesis . In more simplistic terms, one can consider it thus; problem → reaction → solution. Although this model is often named after Hegel, he himself never used that specific formulation. Hegel ascribed that terminology to Kant.  Carrying on Kant's work, Fichte greatly elaborated on the synthesis model, and popularized it.
In the West the choice is basically between a controlled ‘left-oriented’ information, and a controlled ‘right-oriented’ information. The conflict between the two CONTROLLED groups keeps an apparent informational conflict alive. Unwelcome facts that fall into either camp are conveniently forgotten. Books that fall into either camp can be effectively neutralized because they will incur the wrath of both ‘right’ and ‘left’. The faster the cattle run, the faster the treadmill takes them to nowhere.
