人们常常把行动的因果性与人的自由当作两个难以相容的基本观念,在当代哲学伦理学中,这两种观念又以“因果空间”和“理由空间”的隐喻得到更为系统的表现,成为现代伦理学发展的背景观念框架。道德理由与道德行动之间的因果关联性,以及伦理道德规范“规范性”特征的自然主义说明,既是现代伦理学理论的基础性问题,也集中体现了科学时代伦理学思考的要求。沟通这两个空间,在“科学”与“自然”的观念背景中为伦理学奠定基础,是伦理学要解决的时代主题。 People often regard causality of action and human freedom as two incomprehensible basic concepts. In contemporary philosophical ethics, these two concepts are again based on the metaphor of “causal space ” and “space of reason ” Get a more systematic performance, become the background of modern ethics development concept. The causal connection between moral reason and moral action and the naturalistic explanation of ethical norms “normative ” are not only the basic problems of modern ethics theory but also the requirements of ethics thinking in the scientific era. To communicate these two spaces and lay the foundation for ethics in the notion of “science” and “nature” is the theme of the times to be solved by ethics.
