The Titans are the force of will, proceeding as nature (Kronos) from the original universal spirit (Uranus). Here we have to think not merely of will-forces in an abstract form, but of actual will-beings. Prometheus is one of them, and this describes his nature. But he is not altogether a Titan. In a certain sense he is on the side of Zeus, the Spirit, who enters upon the rulership of the world after the unbridled force of nature (Kronos) has been subdued. Prometheus is thus the representative of those worlds which have given man the progressive element, half nature-force, half spiritual force, man's will. The will points on the one side towards good, on the other, towards evil. Its fate is decided according as it leans to the spiritual or the perishable. This fate is that of man himself. He is chained to the perishable, the eagle gnaws him, he has to suffer. He can only reach the highest by seeking his destiny in solitude. He has a secret which is that the divine (Zeus) must marry a mortal (human consciousness bound up with the physical body), in order to beget a son, human wisdom (the Logos) which will deliver the deity. By this means consciousness becomes immortal. He must not betray this secret till a Mystic (Heracles) comes to him, and annihilates the power which was perpetually threatening him with death. A being half animal, half human, a centaur, is obliged to sacrifice itself to redeem man. The centaur is man himself, half animal, half spiritual. He must die in order that the purely spiritual man may be delivered. That which is disdained by Prometheus, human will, is accepted by Epimetheus, reason or prudence. But the gifts offered to Epimetheus are only troubles and sorrows, for reason clings to the transitory and perishable. And only one thing is left--the hope that even out of the perishable the eternal may some day be born.
