Phenomenology and psychopathology are two disciplines whose development intertwined over the past century thanks to key figures such as Binswanger, Jaspers, Fanon, Basaglia. Phenomenology offers psychopathology an approach that looks at the lived experience of the patient without presuppositions and preconceptions. Psychopathology offers phenomenology the possibility to investigate the manifold forms of plurality, a topic that only tangentially has been investigated by philosophy in its history. In that sense, phenomenological notions such as epoche, first and second person perspective, lived time, and intersubjectivity are key to the advancement of a psychopathology, capable of truly understanding the lived experience of the person affected by a disorder and integrate it in society. Consequently, disorders such as autism, schizophrenia, bipolarism, borderline personality have gained a deeper understanding and integration in the society thanks to the combination of phenomenological studies within a multidisciplinary context (music, dance, theatre, visual arts).
