Abstract
Starting from the question of Émile Bernard to Cézanne: “nature and art are not different?”, and the painter’s answer: “ I would like to join them”, we thought that it would be possible to link the spirit of this sentence with the advances of the art in the 21st century. Cézanne’s attitude designs the union between the two realities: art and nature. This union, in the 21st century, has a new artistic representation called bio-art. With bio-art the dichotomy between art and nature disappears and the artistic-scientific product, as a phenomenological object, is a new substance and opens a new ontology.
