The concept of mimesis is, since ancient times, one of the concepts that shapes the structures of Western thought. The two most influential thinkers of Greek philosophy, Plato and Aristotle, gave two different readings of mimesis, relying on the intrinsic ambiguity of this concept. Through a formal analysis of this ambiguity, we propose to think about the new forms of mimesis that take place in the digital age – especially between human beings and machines –, a historical moment that, it is said, leads to the disappearance of any distinction between model and copy.
