研究互联网究竟具有什么样的特征,是我们把握当前时代特征的前提。本文认为,从悖论的视角入手,能更好地揭示互联网的特征,更深刻地理解互联网何以对人类社会生活产生如此错综复杂的影响。互联网在其发展历程中,始终存在着五个悖论性特征:自由与控制、分布与集中、虚拟与现实、咫尺与天涯、无限与匮乏。 Studying exactly what kind of features the Internet possesses is a prerequisite for us to grasp the characteristics of the present era. This article argues that from the perspective of paradox, we can better reveal the characteristics of the Internet and understand more deeply how the Internet has such an intricate impact on human social life. There are always five paradoxical features in the development of the Internet: freedom and control, distribution and concentration, virtuality and reality, proximity and horizon, limitlessness and lack of progress.
