两晋南北朝的政治活动深受占星术的影响和支配,星占之辞既是决策时考虑的关键因素,也是政治斗争中的另类“武器”。帝王们常将其当作确立“天命”的重要工具,为改朝换代制造舆论,臣下也通过天象变化来劝诫君王,防止其权力过度膨胀。由于占星术对于专制主义中央集权亦存在不利影响,故各政权多对其进行严格控制,以便达到官方垄断的目的,此种即禁即用的双重政策贯穿于历朝历代。 Political activities in the Southern and Northern Dynasties were deeply influenced and dominated by astrology. The speech of Astrology was both a key factor in decision-making and an alternative “weapon” in the political struggle. The emperors often regarded it as an important tool for establishing “Heavenly Destiny” and created public opinion for the regime change. As a result, as a result of the astronomical phenomena, the subordinates advised the king to prevent over-expansion of their power. Astrology also has an adverse effect on authoritarian centralization, so the regimes exercise strict control over them in order to achieve the goal of an official monopoly. Such a dual-use ban policy runs through all previous dynasties.
