Why should one go to see works of art if one can look at faces in clouds and other somewhat more complex forms in tarmac? Does my aesthetic experience discover something unprecedented when it takes products of human Intentionality as substrate rather than “natural objects” supposedly lacking all Intentionality? These questions raise that of the contribution of authorship in the framework of aesthetic experience ; they question the role of the author from one of a number of possible points of (...) view. The aim here is to advance this thought setting out from an experience of thought. Borrowing from the methodology of Arthur Danto displayed in The transfiguration of the commonplace, this experience of thought seeks to determine the structural differences between an aesthetic experience undertaken concerning Robert Smithson’s Spiral Jetty and that undertaken concerning an indiscernable perceptible said to have been generated randomly by nature. The question at the heart of this article is how to characterize the difference implied by the presence of the data-author for the aesthetic experience (transl. J. Dudley). (shrink)
