Complexity – At the limit of the (im)possible is collaborative project between Jorge Louçã and Luís Antunes, from the Institute for Complexity Sciences, and David-Alexandre Guéniot and Patrícia Almeida from Ghost Editions. It began with a multidisciplinary seminar that took place in June 2014 at the Arrábida Convent. It brought together dozens of participants coming from different fields of sciences and arts to debate the issue of creativity in their respective disciplines (neuroscience, economics, sociology, theatre, dance, music, cooking, among others). Taking the form of a treasure hunt and a speculative editing exercise, the publication was intended simultaneously as an echo and an extension to the debates and presentations that took place during the seminar. Participants: João Branquinho, Helder Coelho, Luís Antunes, Artur Almeida, Manuel João Ramos, Jorge Louça, F. Pedro Oliveira, Pedro Boleo, João Fiadeiro/Atelier Real, Luís Correia, Francisco Louça, Rosa Perez, Luís Sottomayor, Pedro Lemos, Mário Laginha, David-Alexandre Guéniot e Patrícia Almeida/GHOST.
