Frontier is a compilation of articles that takes us on the path of the incessant questioning that Arnaud Nouqué undertook from a young age: Why do we lie? Where can the FRONTIER be placed between lies and denial? Is this border what separates us or is it the relationship itself? Through the themes of Love, religion, power and fear, we encounter pragmatic answers, stemming from his strong critique of the pyramidal structures of social organizations. Arnaud Nouqué warns us about the era of expertise that generates more and more specificities without relating them in a global perspective. From this hypothesis, the author proposes a strategy of analysis and action: to put back in correlation the content and the form. How can we do this? Through the Dynamic method: an analysis grid and a tool that can be used by those who accompany others as well as those who are on the dizzying journey of self-analysis.
