A theoretical article. Solitude is defined as an affect which expresses the remove, or the limit, between external objects and internal objects that are good enough to enable a subject's creative activity. This remove is just what is critical in adolescence. Desolation is the internal void of the psyche that finds no traces for its creativity in its environment. Desolation would be the basis of psychotic processes of depressive, hallucinatory and paranoiac modes.
