Plato and the Eternal Return

I've been thinking about Plato's idea that we already know everything that there is to know. We just have to remember it. What if that were true? What would happen if we didn't learn everything in our first life? Would we come back much like in buddhism where people are always trying to achieve nirvana and those that do not coem back until they do? That would certainly help us to learn, and it would also connect us to another concept of the class, the myth of the eternal return. We are in a cycle of return that would only end once we find a way to remember all that we had forgotten.

If anyone has any thoughts please feel free to comment.
