The second corresponds to the definition of a relationship between entities (it is a reformulation of the former  Figure T).  The third term corresponds to the Rules and the Questions, and it constitutes the most important tool for research within this model, for they will be used to formulate problems and their solutions. The last three terms correspond to (a) the subjects addressed by the Ars, (b) virtues, and (c) vices.

They are 54 principles in total, which constitute the basis of the whole system and whose relationships are established through the figures.
