The author examines whether Kantian ethics would condone the use of pharmaceutical drugs to enhance one’s moods and cognitive abilities. If key assumptions concerning safety and efficacy, non-addictiveness, non-coercion, and accessibility are not met, Kantian ethics would consider mood and cognitive enhancement to be impermissible. But what if these assumptions are granted? The arguments for the permissibility of neuroenhancement are stronger than those against it. After giving a general account of Kantian ethical principles, the author argues that, when these assumptions (...) are granted, Kantian ethics no longer justifies the prohibition of neuroenhancement, and responds to two objections.

The genetic modification of children is becoming a more likely possibility given our rapid progress in medical technologies. I argue, from a broadly Kantian point of view, that at least one kind of such modification—modification by a parent for the sake of a child's comparative advantage—is not rationally justified. To argue this, I first characterize a necessary condition on reasons and rational justification: what is a reason for an agent to do an action in one set of circumstances must be (...) a reason for any in those circumstances to do the action. I then show that comparatively advantageous genetic modification violates this principle since a child's “getting ahead” through genetic modification cannot be rationally justified unless other children also could receive the modification, thus rendering the advantage useless. Finally, I consider the major objection to this conclusion: it seems to disallow all cases of a parent's helping a child get ahead, something that parents normally engage in with their children. I argue that typical practices of developing a comparative advantage in a child, as well as practices of societal competition in general, do not conflict because they involve circumstances that mitigate the universal character of reasons. Many ordinary cases of competitive advantage that we think of as unjust, in fact, can be explained by my argument. (shrink)

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.
