Every detail of the story requires elucidation in depth. The fleece is something pertaining to humanity that is infinitely precious, something lost since the time of the beginning, and which can be recovered only by the overcoming of terrible powers; such is the situation with regard to the eternal in the human soul. The eternal belongs to human beings, yet we find ourselves divided from it by our own lower nature, and we can attain to it only when we conquer and lull to sleep our lower self. That is made possible when the magic power of our own consciousness (Medea) comes to our aid. Medea becomes for Jason what Diotima was for Socrates when she instructed him in the Mysteries of love. Humanity’s own wisdom possesses the magic power of conquering the transitory and attaining to divinity. From our lower nature, on the other hand, only a debased humanity—the armed men—can spring; this is overcome by spiritual and intellectual means, the advice of Medea. But even when the hero has found the eternal—the fleece—he is not yet safe. A part of his consciousness—Apsyrtus— must be offered up as a sacrifice. This is demanded by the nature of the sense-perceptible world, which is only to be comprehended by us as a manifold, “dismembered” domain. We might go still further into the spiritual processes underlying these images, but the intention here is only to indicate the principle underlying the formation of myths.
