After Meno agrees that Socrates has proven the myth of recollection with the geometric demonstration, Meno says, "But Socrates, I should be most pleased to investigate and hear your answer to my original question, whether we should try on the assumption that virtue is something teachable, or is a natural gift, or in whatever way it comes to men." How does Socrates interpret this request?
This request follows reasonably from their previous conclusions, so Socrates asks if virtue is a form of knowledge, which is teachable.
Unable to answer such a basic question, this helps Socrates realize that he is ignorant.
This indicates that Meno's desires still rule him, despite Socrates' many efforts.
This is refreshing because it is a brand-new direction for their inquiry.
