According to what Steven Mizrach says in “Orality and teleliteracy”; human communication begins with primary orality – the ability to speak with others. Human linguistic competence begins with a series of evolutionary changes both in the structure of the brain (Broca’s Area) and the larynx, palate, et al. which result in more complex abilities of vocalization. Humanlike speech probably has existed for 300,000 years or more among our hominid ancestors, growing from simple grunts and other forms of onomatopoeia, to the development of distinct spoken languages with grammar, morphology, and syntax, as we know them today. Oral speech is always expontaneous, non-linear and oponed since we create it from the unconscious.
As Walter J Ong says in his book “Orality and Literacy: The technologizing the World”, writing (and especially alphabetic writing) is a technology, calling for the use of tools and other equipment: styli or brushes or pens, carefully prepared surfaces such as paper, animal skins, strips of wood, as well as inks or paints, and much more. Clanchy (1979, pp. 88-115) discusses the matter circumstantially, in its western medieval context, in his chapter entitled ‘The technology of writing’. Writing is in a way the most drastic of the three technologies. It initiated what print and computers only continue, the reduction of dynamic sound to quiescent space, the separation of the word from the living present, where alone spoken words can exist. By contrast with natural, oral speech, writing is completely artificial. Writing or script differs as such from speech in that it does not inevitably well up out of the unconscious. The process of putting spoken language into writing is governed by consciously contrived, articulable rules.
However, to say writing is artificial is not to condemn it but to praise it. Like other artifical creations and indeed more than any other, it is utterly invaluable and indeed essential for the realization of fuller, interior, human potentials.
Finally, we can fing the hypermedia, the lasto f these three. Hypermedia is a term created by Ted Nelson, and used in his 1965 article Complex information processing: a file structure for the complex, the changing and the indeterminate. It is used as a logical extension of the term hypertext, in which graphics, audio, video, plain text and hyperlinks intertwine to create a generally non-linear medium of information.
