This kind of thing makes me intensely uncomfortable, given that Wendell Berry is basically my spirit animal. But her points are really compelling. What's the difference between repairing damage (cochlear implants) and enhancing a healthy body? I love her rule: "You should not only be better when you’re using it, you should be better when you turn it off."

Also (for the christians out there), as someone who believes in the Fall of Man, we are all broken in some way, so every enhancement that brings us closer to the way we were created (in God's image) is actually damage repair, even brain implants to bring us closer to health and holiness. My only doubt is whether we have the wisdom to pull off a work that seems to belong to God.
