Tetrads: McLuhan’s Laws and SQL

I have been going over all the past material in this blog as I am now working on my book. One of the things I am clearing up is my understanding of McLuhan’s Laws of Media known as Tetrads. All that McLuhan discovered and I don’t mean to diminish his work is discover the four manipulations that are possible with any form of media including data.

McLuhan’s four Laws of Media were:

  1. Retrieve
  2. Enhance
  3. Reverse
  4. Obsolesce

The four correspoding manipulations are:

  1. Select
  2. Insert
  3. Update
  4. Delete

Please dismiss any past correlations I made between the Manipulations and Laws of Media with the Six Interrogatives.

The McLuhan “Hexad”

When two systems encounter one another they make contact through a medium.

What that medium is is actually irrelevant.  All media are prone to the same set of costs, benefits and violations within their context.  For example whether you medium is sound, documents or email it is possible to commit identity theft, generate spam or hold a constructive exchange.

In my previous posts I made the case for hexads over tetrads.  Then I cleaned up my insideness and outsideness concept.  I am now, going to make an intuitive leap now in dealing with Marshall McLuhan’s Laws of Media Tetrad and convert it into a Hexad as follows:

As you can see the additional two things that media does is recieve-transmit and translate.  I have modified McLuhan’s Figure-Ground binary model into a Figure, Figure-Ground, Ground trinary model.  I may be excommunicated by the media theorists, but I think it is worth the risk.
