I continue to be shocked at how Socrates smacks of the Christian theology I'm so familiar with. I knew about his ideas on the soul and forms, but all the talk about the soul "rising" up to a higher plane of perfection was something I didn't know. That proto-heaven was a sort of a revelation to read about.
Also, the idea that a soul can traverse between the higher plane and the lower sounds vaguely Eastern. The whole Bodhisattva idea of the returning soul is revolutionary to hear about in this Greek text.
