Logos is the formal cause of the kosmos and all things, responsible for their nature and configuration.
The logos of creation, 'And God Said ...' formed the basis of Christian interpretation of the 'Book of Nature.
The laws of the media, in tetrad form, bring logos and formal cause up to date to reveal analytically the structure of all human artefacts.
In Tetrad form, the artifact is seen to be not neutral or passive, bur an active logos or utterance of the human mind or body that transforms the user and his ground.
