Who wrote extensively about feelings, mental anguish and conflict during the early Middle Ages which laid the groundwork for modern psychodynamic theories of abnormal behaviour?

St. Augustine

The correct answer is Option 2: St. Augustine

In the Middle Ages, demonology and superstition gained renewed importance in the explanation of abnormal behaviour. Demonology related to a belief that people with mental problems were evil and there are numerous instances of ‘witch-hunts’ during this period. During the early Middle Ages, the Christian spirit of charity prevailed and St. Augustine wrote extensively about feelings, mental anguish and conflict. This laid the groundwork for modern psychodynamic theories of abnormal behaviour.
