 The importance of the  Demonstrative Figure  resides in its being a step towards the universalization of the Ars, for it initiates a process of greater abstraction of the principles. Even though the terms used in the original figures are kept, they, as well as the figures themselves, have been substituted for letters. At the same time, it is a figure that rotates, which evidently shows the combining character of the Ars. Finally, it opens up the Ars beyond its own principles, to be used in other fields, such as theology, philosophy, and law.
