For those interested in transhumanism, cognitive enhancement, and the potential ethical problems that follow, this interview with Duke Philosophy Professor Allen Buchanan might be of interest. Buchanan has written extensively on the ethical implications of human enhancement, notably in his book Better than Human, and has argued forcefully in favour of pursuing cognitive enhancements.
Buchanan disagrees with critics who suggest that cognitive enhancement should not be pursued, in part, because it’s antithetical to human nature. In fact, he argues that the desire to improve our capacities, and our ability to do so, constitutes an important part of our nature.
I think that any appeal to the notion of human nature, on either side of the enhancement debate, is tricky and problematic and has to be handled with care. Yes, in one sense we might say that it’s part of human nature to strive to improve our capacities. Humans have done this in the past by developing literacy and numeracy, and the institutions of science, and more recently we’ve done it with computers and the Internet. So, yes, if an alien were looking at humanity and asking “What is human nature?” one of the ingredients is going to be that these beings seem quite concerned with improving their capacities and they seem to have a knack for doing it.
