Even if Lotman’s theory has often been presented as a semiotic theory based on categories of space, temporal categories are crucial as well. And as we can speak of polyglotism as one of the main features of culture, we should speak of polychronism as well. In each state of culture, in fact, we find many temporal codes, and the internal dialogue is not only based on codes coming from different spaces (in the normal sense of polyglotism), but also as coming from different times (in the sense of a sort of polychronism). Lotman’s reflections about this aspect of culture could be very useful in order to understand some aspects of our society, where we find a form of presentism, the temporal dimension corresponding to localism within the spatial dimension, which globalization has produced.
