Final answer:
Freud's idea of psychoanalysis, also known as the talking cure, aimed to help people's mental illness by exploring buried, suppressed ideas that caused physical symptoms.
Step-by-step explanation:
Freud's idea of psychoanalysis held that people's mental illness could be helped by means of the "talking cure." The talking cure involved the therapist and the patient recounting memories, dreams, and events to uncover buried, suppressed ideas that were causing physical symptoms. Freud believed that childhood traumas and the development of sexual identity were common causes of mental illness. By exploring these issues, Freud hoped to bring about healing and the possibility of happiness.
