David shambaugh , a china specialist at george washington university , says that over the past three years there has been a " period of retrogression , where the system cannot seem to take the initiative " .
So even if we grant for the moment menger 's argument that the truth will spontaneously triumph in some unspecified long run after all economic errors have finally played themselves out , in the interim , periods of serious scientific retrogression may occur that destroy the economic basis of culture and civilization .
In any case , it 's very hard to say whether this is an age of unparalleled progress , or unparalleled retrogression , disintegration , and decadence .
无论如何，我们都很难说这个时代是一个空前进步，或空前退步，崩溃或者堕落的时代。
The anti-communist die-hards have their idea of unification , they want to unify us into splitting and retrogression .
反共顽固派有一套统一论，要我们统一于分裂，统一于倒退。
Therefore , there is never a moment of retrogression or deterioration or decline .
