We live in a world of phenomena created by the human mind and by human experience, namely conflict, aggression, aggressiveness and violence. These phenomena are viewed as constructs of the mind, types of behaviour, particular experiences and emotional states, specific social interactions or even historical and political categories such as social movements, wars, angry social protests etc. The study explores the notions of aggression and violence and from an individual and a social perspective analyses their determinants in various environments in childhood, adolescence and adulthood. It is an attempt to join the global discussion on reaction conditions and key points that are connected with the risk of pathologization of the personality and its behaviour.
