Explanation:

From ancient times thinkers, philosophers and theologians from all over the world and from all cultures have tried to understand issues concerning human nature such as perception, consciousness and madness. Although these studies are considered to be the first 'psychological theories', psychology itself has its roots in studies of Greek philosophers (dating approximately 700 BC), but only separated from philosophy in the mid-nineteenth century.

For this reason, we may conclude that before psychology became a recognized academic discipline, the affairs of the mind were undertaken by those in philosophy.
