After having developed a reflection on Literature, History, Word and Love from the point of view of complexity, a thesis is presented here regarding the network linking emotions, feelings and thought. There is also an appendix to the aesthetic approach that represents a new branch of that tree. What is expressed here interconnects in a reticular way with the previous reflections that support it and of which it represents a further support. Reflection seeks to connect recent developments in neuroscience with the personal experience of a lifetime. The approach is not only academic but also heuristic: in this way it is possible to bring to light spaces that are normally overlooked and thus open new doors that everyone has the opportunity to cross.
