the 64 items that represent the thematics under which problem elements can occur
The variations describe the thematic message and the development of that message in the story. Variations are measuring sticks by which the author wishes his message to be evaluated. It is the discrepancy between opposing ways of evaluating the meaning of the story that creates the thematic statement as to which is the best way or that one way is no better or worse than another. There are 64 Variations in the Dramatica structure, 16 to each Class.
