Several theories or models seek to explain the causes (etiology) of mental disorders. These theories may differ in regards to how they explain the cause of the disorder, how to treat the disorder, and how they classify mental disorders. Theories also differ about the philosophy of mind they accept; that is, whether the mind and brain are identical or not.[citation needed]
