In this paper, we aim to show that the shape of reality is so far from us that any intent to say it is doomed to failure. A nice approach to fiction as the seamy side of language leads us to consider that the question of reality should be asked in terms of fiction : what does fiction tell us about how we deal with reality? The answer to this question reveals that existence is not the guarantee of what we are used to call genuine knowledge. Indeed, knowledge should be understood as a type-identified set of propositions in ontology which basis is the same as the one of fictional terms ; with this basis always lingering out of reach.
