Myth provides the framework for any comprehension we have about moral truth--that's the way it was for the ancients, and that's the way it is for us. Mythos operates at a level deeper than what we call "belief systems", because belief systems are too rational, too open to comparison in a market of competing belief systems. Belief systems are profane ideologies even if they are religious, like Christian or Islamic fundamentalism. Myth, like poetry, uses language to represent what is incomprehensible in terms of our ordinary states of consciousness. It establishes some common ground with the familiar, but draws us into unfamiliar depths.
Myth thrives, therefore, only where there is the possibility to experience depth upon depth of sacred meaning, and fundamentalism and rationalism are terrified of depths because they lose control there. Mythos withers in the fluorescent glare of a hypertrophied rationality, and it suffocates in the oxygenless chambers of fundamentalism and dogmatism. For mythos to be mythos it has to deliver a sense of the sacred, a sense of the near presence of the gods, of angels, of the ancestors, of the beloved dead, and that we are all part of a cosmic web of relationships which is there for us to discover if we have any desire to understand what the meaning of our lives is. If we have any desire to understand what it means to live a good life, that is, to have some understanding about why what we do or fail to do matters, why our life adds up to something or fails to.
What we know is dwarfed by what we do not know. And yet whatever part of that ocean we have explored and have gotten to know is connected to the vastness that lies beyond it. And we can deduce some things about what the ocean is like elsewhere based on what we have learned about it locally, but such deductions are provisional at best. How the ocean works near the surface is quite different from how it works in its deepest depths, and what might be true about its laws here could be very different from its laws there. And yet there is a continuum that connects there with here.
