Psychoanalysis is a set of theories and therapeutic techniques used to study the unconscious mind. Schopenhauer says that the will is in a continuous struggle and is manifested by obtaining pleasure. The will is unconscious, but it manifests itself in sexual desire. Freud's theses on love and death come to remove metaphysics. Metapsychology refers to the whole of the unconscious, as well as the structures that build its relationship with consciousness.
