Environments are invisible. Their groundrules, pervasive structure, and overall patterns elude easy… — Marshall McLuhan

The professional tends to classify and to specialize, to accept uncritically the ground rules of the environment. The ground rules provided by the mass response of his colleagues serves as a pervasive environment of which he is contentedly unaware. (p. 93)

There is absolutely no inevitability, so long as there is a willingness to contemplate what is happening. [A chapter sub-heading attributed by McLuhan to Alfred North Whitehead]

Art is whatever you can get away with.
