It seems to me that the most promising trends that have developed in the context of semiotic structuralism are linked to its phenomenological background and, from a formal point of view, to topology. Phenomenology has mainly been used to describe the emergence of meaning on the basis of perception. Topology remains the best way of distributing semantic elements within the narrative grammar, as R. Thom has shown, but also of organising the practical field, if we think of forms of life, and of distributing our literary or philosophical imagination in spaces that are their own. We may well wonder to what extent the new objects of study that the passage of time is necessarily proposing to our thinking will require new inventions, new theories or even a few breaks with the past. An object of study cannot simply be treated as an object, but requires an answer to the questions it poses itself. This is true of algorithmic languages, which are based on logical conceptions of thought and are therefore, by their very nature, quite distant from the structural and topological notions mentioned above. We could even, without too much caricature, oppose the fundamental iconicity linked to the structural imaginary and the sequence of symbols in a logical machine. But it seems to me that the new objects that semiotics has set itself give new interest to these problems.
