Before moving to the article, meditate on the following quote inspired by Parmenides.
Temporary is not real. –Hegel (1770-1831)
This article is not closely Hekate related but understanding Parmenides will help you understand Platonism. Read this article, buy the platonic dialogue Parmenides, read at least twice, slowly, following all the logical puzzles and come back to the article. You may also proceed with the surviving excerpts from Parmenide's poem and further studies on the nature of the On.
Timaios is one of the dialogues of Plato, which the great philosopher wrote in his latest years. It is a continuation of “About Town” or “About Justice” and after that, Kritias should be read, at least the fragment that is has survived to us. Another title for Timaios is “About Nature”. It was the main text of cosmology till 13th century, when the Physics and Metaphysics of Aristotle were discovered. The first two parts have been survived in latin and the third in hellenic. Plato uses Physics, Astronomy, Mathematics, Pathology, Cosmology and Metaphysics in his dialogue.
On the work of Proclos, Commentaries on Timaios, we read a comment about a platonic teaching concerning the positioning of the soul. Porphyrios, Iamblichos and Proclos give their views. Read the following text having in mind that the Goddess Hekate is the cosmic soul, the soul of the universe, putting the soul of the universe in the middle between the mental and the tangible world.
Plato, Timaios 34b
“He positioned the soul in its middle and spread it all over the world and he covered the outside with the body.”
