Gorean castes are divided into two categories, High castes and Low castes. There are five "High Castes" in place within Gorean society. They are listed below, ranked according to their prominence in Gorean government. Members of a High Caste are permitted the "First Knowledge" and the "Second Knowledge", while Low Caste members are allowed only the "First Knowledge". It is said that the Priest-Kings enjoy both the "First" and "Second", in addition to a "Third Knowledge" as well. To date, no human has ever been allowed to acquire the "Third Knowledge".

Each caste maintains a series of beliefs and rules for its members, which are followed when one is practicing one's profession.
