In your Primer you have a resource that will make you highly educated, but it will never make you intelligent. That comes from life. Your life up to this point has given you all the experience you need to be intelligent, but you have to think about those experiences. If you don't think about them, you'll be psychologically unwell. If you do think about them, you will become not merely educated but intelligent.
