Definition

"The tetrad is arrived at through a process of asking questions, based on historical, social, and technological knowledge of the subject:

• What does any artifact enlarge or enhance?

• What does it erode or obsolesce?

• What does it retrieve that had been earlier obsolesced?

• What does it reverse or flip into when pushed to the limits of its potential?"
