Beginnings of telecommunication relate to coding and telegraphy; the latter is becoming obsolete today, replaced by email. Codes, on the other hand, retain their fundamental importance because of the security demands related to network communication (see e.g. Lubacz 2001). Codes were of course used even in ancient times, but as the first practical code of the epoch of industrial civilization we can count the code of Luis Braille replacing print for blind persons. This code is not digital, but analog-digital: with the sense of touch, a blind person perceives the relative positions (analog information) of embossed points (digital information) on a page. In this sense, this code is closer to actual functioning of human brains than the cognitivist models of brain as a giant digital computer.
