A foundational question in Luigi Pareyson Aesthetics is the ontological character of the formant form. This character is based on the following principle: the ontology of the formant form is in the action of inventiveness and is not in a static state. For the philosopher of formativity it is in this creative, ontological, persevering action that the artist invents the way of doing, unique in the formant form. This unique way of doing makes the work of art blossom as a (...) formed form. In this paper we will try to show both the invention of the way of doing and the work of which one has an image ratify the singularity of the formant form. If the inventor does the work at the same time he invents the formed form, the just form, it is not a matter of passivity or inertia, but an action of inventiveness. Therefore, one can say the artist's personality is not separated from the formant form, on the contrary, it emphasizes the inseparability of the concepts of making / inventing, formant form and person, without however, affecting neither the unity, nor the identity of the work.
