Our reflection testifies to complexity for the thought to be mixed in order to preserve our freedom of expression. It rises up in front of a globalisation that pushes us into a corner and reveals the limits of interacting systems (economic, ecological, psychological, etc.). It questions the possibilities of opening our systems to new knowledge, in front of the power of disciplinary emissions of knowledges. Our writing practices 'deconstruction' and among other things, of language at the play of the meaning of words. It manages to disturb the pre-established order that precedes reading, as the space of the word, to unfold its meanings with the use of the hyphen. Our text opens up a thought creativity space, like that between letters, words, the line spacing, proper to the interstice, favourable to the impact of silence. It offers a lantern for exchange, unfolds a map, a parchment of serendipity and indisciplinarity, delivers l’espacentre, a concept and its paradigmatic invitation. We propose a modelling, to the opening of possibilities, around to understand and give meaning, with regard to the 'complex thought' of Edgar Morin.
