这是托马斯·莱塞尔教授在2003年10月31日所作的退休演讲。文中提到.任何一种人与人之间持久的社会关系都是受到规范调整的。社会规范可以分为有约束力的规范和无约束力的规范。其中,根据其效力来源和适用范围的不同,有约束力的社会规范又可以进一步分为宗教规范、道德规范、法律规范和礼仪规范。道德规范和法律规范是现今社会中最为重要的两种。尽管它们在强制程度和调整范围等方面有所区别,但在一定程度上也具有共同的根源和内容。 This is a retired speech by Professor Thomas Lisssel on October 31, 2003. The article mentions that any kind of long-lasting social relations between people are regulated. Social norms can be divided into binding norms and non-binding norms. Among them, according to their different sources of effectiveness and scope of application, binding social norms can be further divided into religious norms, moral norms, legal norms and etiquette. Ethics and legal norms are two of the most important in today’s society. Although they differ in terms of the degree of compulsion and the scope of adjustment, they also have a common root cause and content to some extent.
