The modification might be medicine that makes you smarter, an implant that gives you a ‘new’ memory, or perhaps a physical prosthetic that allows you to control devices with your brain.
Secular approaches to bioethics, he explains, inevitably end with the subject of the change deciding for themselves whether the modification is an improvement or not.
This leads Cole-Turner towards an interesting question:
What are we to think if, after the technological enhancement, there is a change of mind – literally? Before the modification, the person completely understands and truly believes that the change is an enhancement. After the modification, the person completely understands and believes that it is not an enhancement, not because anything went wrong but because the enhancement worked and the moral core of the person has been changed. In such case, is the change an enhancement?
The thought experiment is a reminder of a much older story:
The serpent was the shrewdest of all the wild animals the Lord God had made. One day he asked the woman, “Did God really say you must not eat the fruit from any of the trees in the garden?”
“Of course we may eat fruit from the trees in the garden,” the woman replied. “It’s only the fruit from the tree in the middle of the garden that we are not allowed to eat. God said, ‘You must not eat it or even touch it; if you do, you will die.’”
“You won’t die!” the serpent replied to the woman. “God knows that your eyes will be opened as soon as you eat it, and you will be like God, knowing both good and evil.”
The serpent convinces Eve to be disobedient by convincing her of the fruit’s enabling power. Eve quickly realises that though the serpent told the truth, the ‘enhancement’ was a trap:
“The serpent deceived me,” she replied. “That’s why I ate it.”
And according to the Christian story, the consequences are realised by Eve, humanity – and ultimately by God – at incalculable cost.
