But the phonetic alphabet was radically different from the older and richer hieroglyphic or ideogrammic cultures. The writings of Egyptian, Babylonian, Mayan and Chinese cultures were an extension of the senses in that they gave pictorial expression to reality, and they demanded many signs to cover the wide range of data in their societies—unlike phonetic writing, which uses semantically meaningless letters to correspond to semantically meaningless sounds and is able, with only a handful of letters, to encompass all meanings and all languages. This achievement demanded the separation of both sights and sounds from their semantic and dramatic meanings in order to render visible the actual sound of speech, thus placing a barrier between men and objects and creating a dualism between sight and sound.
