“A playwright is a craftsperson, and a play may be said to be designed and built, unit by unit, action by action, word by word. Each play has a finite number of units, even when the multiplicity and complexity of the units seem to be infinite and defy analysis.
Because plays are constructed from units you can examine, they are open to analysis. You may search for the nature and structure of the play by correctly identifying the parts and by perceiving the patterns in which the playwright has arranged the parts.”1
