More on cognitive enhancements

Here's an interesting piece by Ross Andersen in the Atlantic on cognitive enhancements and trans-cranial direct current stimulation, which I wrote on in last Friday's newsletter. It's interesting how science fiction films have thought out these questions ahead of most academics - so they are the maps and symbols that guide us as we try and engage with the future.
I also think the philosopher Allen Buchanan makes a very good point, in the Atlantic piece, when he says perhaps what defines human nature is precisely the desire to advance and develop human nature. In other words, the nature of man is, by its nature, unstable, dynamic, over-reaching. That's certainly how Genesis describes it.
