西方社会学家们将社会一分为二成传统社会和现代社会,前者是落后的、封闭的、静止的;而后者是先进的、开放的、流动的。传统社会与现代社会的区别是显见而且多层次的,本文着重从社会交往的视角展现二者的不同。传统社会的社会交往是封闭式、依赖性、单一化的;而现代社会的社会交往则是开放式、自主性、多样化的。同时,社会交往与社会进步之间存在着辨证的关系。 Western sociologists divide society into two parts: traditional society and modern society. The former is backward, closed and static. The latter is advanced, open and mobile. The difference between traditional society and modern society is obvious and multi-level. This article focuses on the difference between the two from the perspective of social interaction. In the traditional society, the social interaction is closed, dependent and unitary, while the social interaction in the modern society is open, autonomous and diversified. At the same time, there is a dialectical relationship between social interaction and social progress.
