Recently some bioethicists and neuroscientists have argued for an imperative of chemical cognitive enhancement. This imperative is usually based on consequentialist grounds. In this paper, the topic of cognitive self-enhancement is discussed from a Kantian point of view in order to shed new light on the controversial debate. With Kant, it is an imperfect duty to oneself to strive for perfecting one’s own natural and moral capacities beyond one’s natural condition, but there is no duty to enhance others. A Kantian (...) approach does not directly lead to a duty of chemical cognitive self-enhancement, but it also does not clearly rule out that this type of enhancement can be an appropriate means to the end of self-improvement. The paper shows the benefits of a Kantian view, which offers a consistent ideal of self-perfection and teaches us a lesson about the crucial relevance of the attitude that underlies one’s striving for cognitive self-improvement: the lesson of treating oneself as an end in itself and not as mere means to the end of better output.

It has been proposed that reoffending could be reduced by manipulating the neural underpinnings of offenders’ criminogenic mental features with what have been called neurocorrectives. The legitimacy of such use of neurotechnology – criminal neurorehabilitation, as the use is called – is usually seen to presuppose valid consent by the offenders subjected to it. According to a central criticism of nonconsensual criminal neurorehabilitation, nonconsensual use of neurocorrectives would express a degrading attitude towards offenders. In this article, I consider this criticism (...) of nonconsensual criminal neurorehabilitation. By using cases of autonomous persons who lead a subservient existence as an example, I propose that nonconsensual criminal neurorehabilitation need not express a more degrading attitude towards offenders than consensual criminal neurorehabilitation. The argument of this article does not show that nonconsensual criminal neurorehabilitation is morally or legally acceptable. Yet, in view of the argument, criticizing nonconsensual criminal neurorehabilitation for expressing a degrading attitude towards offenders is not compatible with simultaneously endorsing consensual criminal neurorehabilitation.
