亚当·斯密的“同感说”是其道德情感学说的基础和核心。“同感”产生于“公正的旁观者”的设身处地的想像 ,是在经验基础上产生的一种“公正的”共鸣感情。它的作用是对他人行为和自身行为进行道德评价。斯密把主观的感情当作了客观的评价标准 ,其“公正的旁观者”也是抽象的 ,实际上是不存在的。 Adam Smith’s “Homosexuality” is the foundation and core of his moral and emotional theory. The “same feeling” arises from the imagination of the “just observer”, a feeling of “fairness” based on experience. Its role is to evaluate the ethical behavior of others and their own behavior. Smith regarded the subjective feelings as an objective evaluation criterion, and his “just spectator” is abstract, but it does not really exist.
