 In the ternary form of the Ars, Llull extensively uses the combining structure. Thus, the principles of the Ars—the first and the second meaning of the alphabet—are combined among themselves and the rules to obtain an exhaustive relationship of all that can be affirmed from the combination of the principles and the rules. This is a fundamental tool for the user of the Ars, for it is following this “mixture”, as designated by Llull, of the principles, that the identification of the appropriate principle to solve the questions will be easier. The same combining procedure must be applied to the nine subjects or beings with which Llull has formed a hierarchy of reality—the fourth meaning of the alphabet: God, Angel, Heaven, Man, imaginative, sensitive, vegetative, elementative, instrumentality or artifice. Each one of these must be combined with the principles and the rules to exhaustively obtain what can be said of each one, in order to answer concrete questions. This procedure is also applied to the fifth and sixth meaning of the alphabet, that is, the virtues and vices.
