Religion
The Greater Good, or Tau'va (literally the "Good Greater" in the Tau Lexicon language), is the founding religio-philosophical principle of modern Covenant society which holds that all sentient beings should strive to ensure the greatest good for the greatest number of beings in the galaxy. The Tau'va is based on the Tau-Covenant caste system and is designed to allow for the advancement of the entire Covenant society towards a more successful, prosperous and peaceful existence in the future without much of the violent conflict that marked earlier Tau-Covenant history. The Greater Good was first introduced to the Tau during the Mont'au ("Death Age"), the long period of war fought between the Tau and the Covenant on their homeworld of T'au before the formation of the unified Tau-Covenant Empire under the guidance of the Hierarchs.
This concept involves the pursuit of perfect societal harmony and combines the particular strengths of each caste to counter the many weaknesses and divisions their culture once possessed. Within only a few years after the Hierarchs, and subsequently Covenant, first revealed themselves, Tau culture was dominated by the pursuit of the Greater Good and the Tau-Covenant Empire began its long march towards the development of advanced, starfaring technology. The philosophy of the Greater Good now guides the Tau in their attempts to conquer the rest of the galaxy and unite all the intellignt races in pursuit of the Greater Good. The philosophy forces the Tau-Covenant to both desire to expand their empire for the Greater Good, and to absorb other intelligent races and their cultures into their own, which could ultimately have disastrous effects upon their ability to actually keep their newborn interstellar empire united.
