In tetrad form, the artefact is seen to be not netural or passive, but an active logos or utterance of the human mind or body that transforms the user and his ground.

Formal cause, as logos, incorporates the patterns of side-effects as part of essential nature: tetrads restore poesis and the making process to the study of artefacts.

Each tetrad gives the etymology of its subject, as an uttering or outering of the body physical or mental, and provides its anatomy in fourfold exegetical manner.

All of the new media have enriched our perceptions of language and older media. They are to the man-made environment what species are to biology. (p. 84)

All media are extensions of some human faculty -- psychic or physical.

All of man's artefacts, whether hardware or software, whether bulldozers or laws of chemistry, are alike linguistic in structure and intent. (p. 227)

The media is the thought-form of the technological society, and it finds nothing it does to be laughable, a sure sign that it is not human.

The 4 aspects of each of the media actually constitute the four features of all metaphors. In other words, all human technologies whatever are, in the fullest sense, linguistic outerings, or utterings, of man. (p. 275)

Law and technology produce, together, a kind of regulation of creativity we've not seen before.

Laws! We know what they are, and what they are worth! Spider webs for the rich and powerful, steel chains for the weak and poor, fishing nets in the hands of the government.

Laws are generally found to be nets of such a texture, as the little creep through, the great break through, and the middle size are alone entangled in.

In a media-based society (and of course there is no such thing as a non-media-based society consisting of more than one person) it is the signs and significants, the meanings and habits and conventions of speaking and thinking, the images and stereotypes which control everything. It is important to analyze how it is represented and of course what is not represented or how it lacks representation. It's not so much Rupert Murdoch – whose assholeness I will not dispute – that we should attack, but rather something I would call the cultural grammar of the public space. Power is formed within such a grammar. Access and non-access to each and every thing is regulated in its realm. Meanings are negotiated there.

In the works of the Creator ever open to our examination, we possess a firm basis on which to raise the superstructure of an enlightened creed. The more man inquires into the laws which regulate the material universe, the more he is convinced that all its varied forms arise from the action of a few simple principles. These principles themselves converge, with accelerating force, towards some still more comprehensive law to which all matter seems to be submitted. Simple as that law may possibly be, it must be remembered that it is only one amongst an infinite number of simple laws: that each of these laws has consequences at least as extensive as the existing one, and therefore that the Creator who selected the present law must have foreseen the consequences of all other laws. The works of the Creator, ever present to our senses, give a living and perpetual testimony of his power and goodness far surpassing any evidence transmitted through human testimony. The testimony of man becomes fainter at every stage of transmission, whilst each new inquiry into the works of the Almighty gives to us more exalted views of his wisdom, his goodness, and his power.
