The aim of this article is to rethink the relationship between cognitive sciences and the humanities, based on studies of Old Norse literary tradition. Old Norse literature includes many of the traditional medieval genres in translations, such as saints' lives, historiographies, romances, and chansons de geste. Yet it also includes genres like the Sagas of Icelanders, skaldic poetry, and eddic poetry, which are deemed distinct from other medieval literatures. By discussing (1) creativity and cultural diversity; (2) stories-creation and blending; (3) the continuity in the sense of self; and (4) making choices, from the perspective of cognitive sciences and with examples from the Old Norse literary corpus, this article aims to elucidate the potential for complementarity between the two fields.
