The Tetradoxy is a philosophical disquisition and the fourth disquisition of The Omnidoxy by Cometan and consists of a series of discourses that are particularly focused on the ethics surrounding equality, manners, good deeds, and other actions that are applicable to justice and patience as areas of contemplation.
 
The Tetradoxy, similar to each of the other disquisitions of The Omnidoxy, is designated with its own inclusive discipline known as equitology which encompasses all of the concepts, disciplines of study, beliefs, theories, terms, and notions introduced and categorised as part of tetradoxical study within the Astronic philosophical tradition.
