Myth is the practical metabolism of our soulish life, the logic of our obsessions and oversights for which we have no language or code. Myth is the "morality" that the ineffable puts upon us, our unaccountable imperatives, our inexplicably selective clarity and obscurity, the mortal one-sidedness of our talents and wits, the passion and apathy that make such a transient passage through our hapless minds; that weave a pattern of fatality others will see before we do. Myth is distinctively human or sublime higher-order instinct, the "reason" in culture that reason knows not of.
There is a form of poetic and esthetic and moral genius necessary to make philosophical issues truly incandesce for students, and even though I indeed had some world-class professors myself when I went through the curriculum, I rarely saw such gnosic or concretist/poetic passion among them. I am not speaking of broad histrionics or melodramatic delivery, but rather a moral investment of concern, of loving delight and pathos in exposing one's consciousness to the full horrific and magnificent implications of the materials.
Most humans know their own "reason" only in the sense that Hume defined it, as "a slave to the passions"-and by "passions" he meant not moral passions or the passions of transcendent genius, but only low appetites or base desires, which society and economy ultimately shape and spur on in us.
