These dialogues are really fun and simple, I see why people who’ve read Plato recommend these dialogues to newcomers. That said, I didn’t fully grasp his arguments on the immortality of the soul - some are my fault (I need to go back and work slowly through it and understand the arguments fully) and some are more on Plato to answer (eg, he says the soul is unchanging and is therefore immortal, but if souls don’t change, then why do philosophy at all?). 

Overall though it’s a good climax for Socrates as a character. I love that the core of Socrates message, of having a pure soul and being rewarded after death for it, is almost a direct parallel to the teachings of Jesus of Christian tradition; it’s surprising to see these ideas years before Jesus was born, and coming from philosophy instead of religious belief. It’s hard not to read Phaedo and not become even a little bit more religious than when you went in.
