This is going to sound really obvious, but you can only make analogies with things you know. Or better yet, something known and understood by the people around you. I'm sure there are some subtleties in chariots being pulled by two horses that I'm not aware of, and so Plato's analogy doesn't work for me. We won't be able to compare the brain to anything better than a computer until we either understand the brain better, or until we understand some other brain-analog better.
