What is an emotion and what relationship is established between emotion and experience in the use of an architectural or urban space? We all feel emotions, but it is difficult to define them and understand what they actually are: whether they are shared by all human beings regardless of specific ethnic groups and cultures or, vice versa, whether they are profoundly rooted in time and space; whether they are cognitive phenomena, special sensations generated by conscious thought, or pre-reflective and pre-cognitive bodily responses; whether they are mainly individual or are triggered by social conditioning; lastly, what impact they have on our individual and collective lives.
