Aim of this research’s draft is to understand the place and meaning of the arts in the human frame and society. The main hypothesis is that the role of the arts consists above all in producing objects of interpretation. This is not only a “role”; actually, it is an identity and a meaning. Artworks are tools to be interpreted, meaningful structures that live only to be understood. The rule of the game is that the artwork must be per se significant (even when representing the senselessness of the world). Thus, the artwork activates inevitably a Call for Interpretation (CFI) , which is the fulfillment of its identity. The essay explores the fields of music/poetry and of cave arts, to get a preliminary setting of the scientific proposal.
