Infosphere is a neologism composed of information and sphere. The word refers to an environment, like a biosphere, that is populated by informational entities called inforgs. While an example of the sphere of information is cyberspace, infospheres are not limited to purely online environments. ==History of the Infosphere== The first documented use of the word "InfoSphere" was a 1971 Time Magazine book review by R.Z. Sheppard in which he writes "In much the way that fish cannot conceptualize water or birds the air, man barely understands his infosphere, that encircling layer of electronic and typographical smog composed of cliches from journalism, entertainment, advertising and government." In 1980 it was used by Alvin Toffler in his book ''The Third Wave'' in which he writes "What is inescapably clear, whatever we choose to believe, is that we are altering our infosphere fundamentally...we are adding a whole new strata of communication to the social system. The emerging Third Wave infosphere makes that of the Second Wave era - dominated by its mass media, the post office, and the telephone - seem hopelessly primitive by contrast". The Toffler definition proved prophetic as the use of "Infosphere" in the 1990s expanded beyond media to speculate about the common evolution of the Internet, society and culture. In his book ''Digital Dharma'', Steven Vedro writes, "Emerging from what French philosopher-priest Pierre Teilhard de Chardin called the shared noosphere of collective human thought, invention and spiritual seeking, the Infosphere is sometimes used to conceptualize a field that engulfs our physical, mental and etheric bodies; it affects our dreaming and our cultural life. Our evolving nervous system has been extended, as media sage Marshall McLuhan predicted in the early 1960s, into a global embrace." The term has also been used by Luciano Floridi, on the basis of biosphere, to denote the whole informational environment constituted by all informational entities (thus including informational agents as well), their properties, interactions, processes and mutual relations. It is an environment comparable to, but different from cyberspace (which is only one of its sub-regions, as it were), since it also includes off-line and analogue spaces of information. According to Floridi, it is possible to equate the Infosphere to the totality of Being. This equation leads him to an informational ontology. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「infosphere」の詳細全文を読む スポンサード リンク
