Art brut (also called outsider art) has been receiving well-deserved attention in recent decades and is making its way into important private collections and public institutions. It offers viewers a sincere testimony, conveys emotions in an authentic way and has unique aesthetic qualities. It knows no self-censorship, there are no copies or imitations, and the artworks are not subject to artistic trends and styles. Its creators are usually self-taught solitary authors, cultural outsiders, neurodivergent people or people who have experienced mental illnesses, which in turn liberated their creativity. For all these people, artmaking is an intrinsic need and often becomes a ritual.
