Mythology is not a lie, mythology is poetry, it is metaphorical. It has been well said that mythology is the penultimate truth--penultimate because the ultimate cannot be put into words. It is beyond words. Beyond images, beyond that bounding rim of the Buddhist Wheel of Becoming. Mythology pitches the mind beyond that rim, to what can be known but not told.
Modern romance, like Greek tragedy, celebrates the mystery of dismemberment, which is life in time. The happy ending is justly scorned as a misrepresentation; for the world, as we know it, as we have seen it, yields but one ending: death, disintegration, dismemberment, and the crucifixion of our heart with the passing of the forms that we have loved.
I would say that all our sciences are the material that has to be mythologized. A mythology gives spiritual import - what one might call rather the psychological, inward import, of the world of nature round about us, as understood today. There's no real conflict between science and religion ... What is in conflict is the science of 2000 BC ... and the science of the 20th century AD.
