What is the value of myth?
Professor Glenn R. Morrow defines a myth as a "probable tale" in the Introduction to Benjamin Jowett's translation of Plato's work, Timaeus. Morrow's definition of myth, which he draws from classical contexts, is a far cry from conventional conceptions of a myth as a "Fantastic tale".
From my perspective as an engineer, the idea of myth speaks to the nature of story in a practical and pragmatic sense. A "probable tale" encapsulates the idea that any tale, no matter how carefully crafted, is only an approximation to someone's experience — or even their perspective.
Then what is the value of myth?
Psychologist Carl Jung speaks to the importance of myth in communicating individual perspectives. He viewed science as being too general and abstract to convey the intricacies associated with an individual's life and perspectives. Jung explicitly states this in the Preface to his autobiography. He directly calls attention to the way science uses statistics and averages to develop predictive models and directly questions the ability of science to account for the direct personal experiences of any one individual.
I found Jung's insights indispensable for gaining insight into the impact of myth on a deeply personal level, as I hope you now do!
