Technology is that which separates us from our environment.

The wheel is an extension of the foot, the book is an extension of the eye, clothing an extension of the skin, electric circuitry an extension of the central nervous system.

Once we have surrendered our senses and nervous systems to the private manipulation of those who would try to benefit from taking a lease on our eyes and ears and nerves, we don't really have any rights left. Leasing our eyes and ears and nerves to commercial interests is like handing over the common speech to a private corporation, or like giving the earth's atmosphere to a company as a monopoly.

If the work of the city is the remaking or translating of man into a more suitable form than his nomadic ancestors achieved, then might not our current translation of our entire lives into the spiritual form of information seem to make of the entire.

The medium, or process, of our time - electric technology is reshaping and restructuring patterns of social interdependence and every aspect of our personal life. It is forcing us to reconsider and re-evaluate practically every thought, every action.

New media may at first appear as mere codes of transmission for older achievement and established patterns of thought. But nobody could make the mistake of supposing that phonetic writing merely made it possible for the Greeks to set down in visual order what they had though and known before writing. In the same way printing made literature possible. It did not merely encode literature.

Media are means of extending and enlarging our organic sense lives into our environment.
