Many transhumanists are enthusiastic about the possibilities of cognitive enhancement. Such enthusiasts might say something like: “I want to use advanced technologies – from genetic engineering and psychoactive pharmaceuticals to neural implants and even mind-uploading – to increase my intelligence, to make me ‘smarter, wiser, or more creative’ [PDF], to produce a ‘smarter and more virtuous’ person, to mentally and emotionally augment myself.”More.
But...talk of enhancement presupposes some conception of the self. Specifically, it assumes that the self is capable of enduring such modifications, e.g., as a pattern, or as an immaterial soul, or whatever. The resulting enhanced being would thus still be me, it would just be a different and “better” (according to some set of criteria) version of me.
Now, an interesting paradox arises when one combines the above claims with a specific (and controversial) stance on what the self is...
More importantly, though, it must be pointed out that cognitive enhancement is only one route to the destination of greater-than-human-intelligence: the other is artificial intelligence (AI). Another option would thus be to create a superintelligent AI system that could help us deliberate about whether or not we should use cognitive enhancements. This would offer a way out of the paradox, since it doesn’t involve modifying ourselves.
The trouble is, however, that AI may turn out to be more difficult than enhancing the neurobiological core of Homo sapiens, which means that the paradox would remain intact: in this case, the most feasible way to engender a new species of ultra-smart posthumans would be through human enhancement and not AI.
Finally, one could generalize the basic idea to AI as well. That is, we might pose a general moral question about whether or not it would be good to create a species of posthumans through either method of enhancement or AI. Our ability to answer this question, though, is no doubt far more limited than the ability of a superintelligent biotechnological hybrid or completely synthetic posthuman to answer it.

Phillippe Verdoux on the enhancement paradox
IEET contributor Phillippe Verdoux wonders if enhancing is necessary in order to decide whether or not enhancing is a good idea:
