The vision of humanistic psychology, in this case in Carl Rogers, has been one of the many perspectives that have mediated between the methodologies of behaviourism and psychoanalysis, since it identifies an autonomous subject in itself and free to build its own path through experiences and suffering as formative aspects for life, Within this vision, Friedrich Nietzsche appears as an author who gives more weight to this construction of the subject, which through the moments of nihilism and the will to power complements the proposal of the subject made by Carl Rogers, both authors arriving at a common construct: A Strong Psychological subject.
