Following from an earlier study of ?literate technologies,? the present volume seeks to examine a number of questions that inevitably come to surround any discussion of signification and dynamic systems; questions whichwhat is variously meant by the terms event and state, and which tend to coalesce around a number of ?problems? to do with semiosis, relativity and the discursive character of time or temporalisation, mediality, representation and the ?techno-logisation? of presence.
