There is also a fourth kind of madness—that of love—which cannot be explained without enquiring into the nature of the soul.
All soul is immortal, for she is the source of all motion both in herself and in others. Her form may be described in a figure as a composite nature made up of a charioteer and a pair of winged steeds. The steeds of the gods are immortal, but ours are one mortal and the other immortal. The immortal soul soars upwards into the heavens, but the mortal drops her plumes and settles upon the earth.
Now the use of the wing is to rise and carry the downward element into the upper world—there to behold beauty, wisdom, goodness, and the other things of God by which the soul is nourished. On a certain day Zeus the lord of heaven goes forth in a winged chariot; and an array of gods and demi-gods and of human souls in their train, follows him. There are glorious and blessed sights in the interior of heaven, and he who will may freely behold them. The great vision of all is seen at the feast of the gods, when they ascend the heights of the empyrean—all but Hestia, who is left at home to keep house. The chariots of the gods glide readily upwards and stand upon the outside; the revolution of the spheres carries them round, and they have a vision of the world beyond. But the others labour in vain; for the mortal steed, if he has not been properly trained, keeps them down and sinks them towards the earth. Of the world which is beyond the heavens, who can tell? There is an essence formless, colourless, intangible, perceived by the mind only, dwelling in the region of true knowledge. The divine mind in her revolution enjoys this fair prospect, and beholds justice, temperance, and knowledge in their everlasting essence. When fulfilled with the sight of them she returns home, and the charioteer puts up the horses in their stable, and gives them ambrosia to eat and nectar to drink. This is the life of the gods; the human soul tries to reach the same heights, but hardly succeeds; and sometimes the head of the charioteer
