there is also something curious about a text which refers to itself. What is it? It is what philosophers call ‘indexicality’: the characteristic of certain words which have a different meaning every time they are used, a meaning determined by where, how, when and by whom they are being spoken. Words such as ‘here’, ‘now’, ‘I’, ‘this’, ‘tonight’ all assume a different meaning depending on who utters them and the circumstances in which they are uttered.
