Cosmos

Cosmos is a word used to describe the universe as an orderly and harmonious system, and cosmology refers to the scientific, religious, and philosophical study of the cosmos.

Originally the term cosmos was used by philosophers, such as Pythagorus, as a philosophical description of the moral principals and numerical relationships of the world; and was also used to describe cosmological theories regarding the planets of our solar system acting as instruments of the divine. Pythagorus viewed the cosmos as a set of structured mathematical relationships offering a source of wisdom imbued with moral significance related to reincarnation and fate of the human soul. Pythagorus's idea of cosmos would later be developed by his successors of his Pythagorean tradition into a more scientific and mathematical direction giving rise to the modern definition of cosmos.
