Does this mean that we're doomed when we try to fight fear? I'm not sure it does. I think it's more likely that we're currently fighting fear the wrong way.
Take the classic childhood fear of monsters in the unseen places--under the bed, in the closet, in the dark. How are most of these fears treated? Do we tell children it's natural to be afraid of the unknown, but that these things don't need to stay unknown? Do we hold their hands while they open the doors and look under the bed?
No, or at least not often. Instead, we say, "Don't be silly, honey. There are no monsters. Go to sleep." And we do it at the same time that we're teaching them that there are things in the world to be afraid of.
