Résumé
The so-called "rationality wars" have imposed to find new accounts for the agents' reasoning procedures. I plan to examine the benefits we could draw from an account in terms of narration. Since from an external standpoint an agent's reasons are not necessarily rational, one has to put focus on the etiology of her beliefs, that is, the causal procedures of their production, maintenance and change. To preserve the characters of fallibility, reliability and a-rationality (i.e. they are not content-neutral) of their justification, I rely on Isaac Levi's model of fixation which seems to provide the necessary guarantees. I try to show that such a model may happily be supplemented by a theory of justification as "mini-narratives".
