“是”与“应该”的问题是哲学史上的一大理论难题。麦金太尔以其雄厚的哲学史为基础,以“叙述史”的独特方式,运用功能性概念和目的论概念来缝合它们之间的鸿沟。但麦金太尔的解决方式也有其理论困惑。 The problem of “yes ” and “should ” is a major theoretical problem in the history of philosophy. MacIntyre, based on his strong philosophical history, uses the concept of functionalism and teleology to sew the gap between them in a unique way of “narrating history.” But McIntyre’s solution also has its theoretical puzzles.
