By development outlook is meant one's basic view on social development. Its complexity is involved at 4 levels. At the object level, it comes from the fact that the society is an open complex giant system (OCGS). At the cognition level, it comes from the reductionism and non-system thinking. At the practice level, it comes from the real benefit setup, conservative and unperfect facts of economic-political structure, and the international facts. At the philosophy level, it comes from the unity of opposites.
