This paper refers to the nature of the concept of human time in the twentieth century. The paper is written from the perspective of electronic media of communication and their role in radical changes in the concept of time that has taken place in the twntieth century. A main argument is that electronic media, specifically computers, can simulate more effectively than other media have ever done (as the written word, music, painting etc.) the feeling of intuitive time when, paradoxically enough, computers are basically "intelligent" (rational) technologies.
Another basic argument is the bias of modern life towards "presentness" and "materiality", that is the narrowing of human temporal horizons by the orientation of life towards "now", the parallel degradation of history (past), the neutralisation of uncertainty (future) and the extensive materialisation of memory. It is argued that while technologies (of communitation) themselves are becoming more and more abstract (electronic), memory itself becomes more and more materialised. It will be, conclusively, claimed that electronic technologies of communicating human "meaningful interactions" have played a decisive role to the temporal condition of modern life.
