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?"
