One of the ideas I couldn't shake while reading Meno is the impact genetics could play in regards to natural ability and general tendencies. Obviously, Rosalin Franklin wasn't around to teach Plato all about DNA or the science of inheritance and the level of randomness that comes with it. I think one could argue that to a degree people can be born virtuous in that their genetic makeup can sway them towards having a virtuous nature. And of course kids aren't replicas of their parents (that'd be weird) so a virtuous father can give birth to a scoundrel son. What do you think? Do you think it is possible that the recalling of past knowledge could be simply attributed to the genes rather than a cosmic coincidence allowing people to recall things from before their time.

Let's see if I can get a proper discussion going in the comments.

If good deeds are done because of vanity, are they still good?
