What we mean here is myth in its everyday,
nontechnical sense as understood by you and me: a story that is told as if it were literally true, but which is no longer accepted as factual, and which explains or symbolizes a belief or insight.
In general, while appeal to or reliance upon one's own intuition (in some technically unspecified
sense of the term) may satisfy the informal demands of many ordinary,
nontechnical contexts, such intuitive conviction — however important heuristically to the individual inquirer — may be of no logical relevance to the job of satisfying the technical demands constitutive of some formal arena of discourse.
