Together with the project of revaluation of all values, the schema of a "physiology of art" gains a central role in Nietzsche's last writings. That's a perspective that supposes a defeat both of the "artist's metaphysics" of the initial period and of the critique of romanticism that characterizes a second moment. Taking as a starting point the discussion about the pertinence of utilization of the term physiology in Nietzsche's work, this article intends to present, in general terms, the reaching of this project to the discussion of the relations between art and truth, art and illusion. In conclusion, the intention here is to show the importance of this idea of a physiology of art taking as a reference the figure of the actor.
