 Kermode defines myth as a dangerous fiction used for exploitative purposes.The philosopher Hans Vaihinger has articulated similar ideas, putting forth the biological argument that human beings use fictions to help survive in a hostile environment, and that these fictions are so useful that it becomes most difficult, if not impossible, for us to stop ourselves from creating fictions.In Vaihinger’s language, fiction is something we treat “as if” it is true even when we know that it is not true, whereas myth is something we treat as true because we do not know it is false.
