Carl Friedrich von Weizsäcker treated the problematic implications of scientific-technological progress, emerging in the lifetime of his generation, under the key-word "ambivalence". Obviously it means a proto-theoretical, fuzzy concept that cannot be introduced explicitly per definition; starting with an intuitive perception, "ambivalence" should gradually gain meaning by using it in different argumentative contexts. Following a circular course (Kreisgang)--a procedure typical for Weizsäcker's style of thought--, he moves successively from explicit ambivalence in the application sphere of science through ambivalent features in scientists' behaviour and action up to the general ambivalence of human existence, disclosed only at an anthropological level of deliberation. The given paper delineates the ambivalence concept used by Weizsäcker during the 1960s and 1970s.
卡尔·弗里德里希·冯·魏茨泽克以“二律背反”为关键词，探讨了在他那一代人的有生之年出现的科技进步所带来的问题性影响。显然，这意味着一个原理论性的、模糊的概念，无法通过定义明确引入；从直观感知出发，“二律背反”应通过在不同论证语境中的使用逐渐获得意义。沿着一个循环过程（循环路径）——这是魏茨泽克思维方式的典型过程——他依次从科学应用领域的明确二律背反，经过科学家行为和行动中的二律背反特征，直至仅在人类学思考层面才揭示的人类存在的普遍二律背反。本文阐述了魏茨泽克在20世纪60年代和70年代所使用的二律背反概念。
