Increasing evidence suggests that it is not only the case that brain-based cognitive and emotional processes affect decision-making, but also that decision-making, actions and habits influence in turn the very structure and function of the brain by way of neural plasticity. This indicates that the interplay between brain and agency is made up of a complex feedback loop of reciprocal causality. The assumption that the causal relationship is one way –brain to behavior– results in unsatisfactory neuroscientific analyses of agency. I contend that taking into account reciprocal causality for the purposes of human enhancement is not only a matter of theoretical consistency, but also carries with it important practical implications. Top-down cognitive enhancement –through mind training techniques such as meditation– may have advantages over biomedical enhancement.

We consider the current debate between bioconservatives and their opponents—whom we dub bioliberals—about the moral acceptability of human enhancement and the policy implications of moral debates about enhancement. We argue that this debate has reached an impasse, largely because bioconservatives hold that we should honour intuitions about the special value of being human, even if we cannot identify reasons to ground those intuitions. We argue that although intuitions are often a reliable guide to belief and action, there are circumstances in which they are not reliable. Intuitions—including intuitions about enhancement—are subject to various cognitive biases rendering them unreliable in some circumstances. We argue that many bioconservative intuitions about enhancement are examples of such unreliable intuitions. Given this, it is unrealistic of bioconservatives to expect others to rely on their unexamined intuitions. Furthermore, refusing to engage in debates about the reasons and values that underpin their intuitions about enhancement will have the effect of making bioconservative voices less relevant in policy debates about enhancement than they would otherwise be.

Ought we to improve our cognitive capacities beyond the normal human range? It might be a good idea to level out differences between peoples cognitive capacities; and some people's reaching beyond normal capacities may have some good side-effects on society at large (but also bad side-effects, of course). But is there any direct gain to be made from having ones cognitive capacities enhanced? Would this as such make our lives go better? No, I argue; or at least there doesn't seem to be any evidence suggesting that it would. And it doesn't matter whether we consider the question from a narrow hedonistic perspective, from a more refined hedonistic perspective, from a desire-satisfaction view, or from some reasonable objective list view of what makes a life go well. Only an extremely perfectionist – and implausible – view of what makes our lives go well could support any direct value in cognitive enhancement. Finally, our sense of identity gives us no good reasons to enhance even our capacity to remember. So, cognitive enhancement as such would not improve our lives.

This article provides an answer to the question: What is the function of cognition? By answering this question it becomes possible to investigate what are the simplest cognitive systems. It addresses the question by treating cognition as a solution to a design problem. It defines a nested sequence of design problems: (1) How can a system persist? (2) How can a system affect its environment to improve its persistence? (3) How can a system utilize better information from the environment to select better actions? And, (4) How can a system reduce its inherent informational limitations to achieve more successful behavior? This provides a corresponding nested sequence of system classes: (1) autonomous systems, (2) (re)active autonomous systems, (3) informationally controlled autonomous systems (autonomous agents), and (4) cognitive systems.

This article provides the following characterization of cognition: The cognitive system is the set of mechanisms of an autonomous agent that (1) allow increase of the correlation and integration between the environment and the information system of the agent, so that (2) the agent can improve the selection of actions and thereby produce more successful behavior.

Finally, it shows that common cognitive capacities satisfy the characterization: learning, memory, representation, decision making, reasoning, attention, and communication.

This thesis argues that the neuroethical debate regarding cognitive enhancement drugs, as it stands, expounds arguments that fail as a result of the success of the Extended Cognition thesis. Instead this thesis suggets that arguments that support the ethically problemtatic nature of cognitive enhancement drugs focus on the metaphorical influence they have on the self.

This paper identifies human enhancement as one of the most significant areas of bioethical interest in the last twenty years. It discusses in more detail one area, namely moral enhancement, which is generating significant contemporary interest. The author argues that so far from being susceptible to new forms of high tech manipulation, either genetic, chemical, surgical or neurological, the only reliable methods of moral enhancement, either now or for the foreseeable future, are either those that have been in human and animal use for millennia, namely socialization, education and parental supervision or those high tech methods that are general in their application. By that is meant those forms of cognitive enhancement that operate across a wide range of cognitive abilities and do not target specifically ‘ethical’ capacities. The paper analyses the work of some of the leading contemporary advocates of moral enhancement and finds that in so far as they identify moral qualities or moral emotions for enhancement they have little prospect of success.

In this article, we analyse content from two recent reports to examine how a public health framework to cognitive enhancement is emerging. We find that, in several areas, these reports provide population-level arguments both for and against the use of cognitive enhancers. In discussing these arguments, we look at how these reports are indicative of potentially innovative frameworks—epidemiological, risk/benefit and socio-historical—by which to explore the public health impact of cognitive enhancement. Finally, we argue that these reports are suggestive of both tensions between the bioethical and public health approaches and are also indicative of how these two frameworks can, in part, be seen as complementary.

This paper considers the range of possible policy options that are available if we wish to attempt to treat people with cognitive disabilities as equal members of society. It is suggested that the goal of policy should be allow each disabled person to establish a worthwhile place in the world and sets out four policy options: cash compensation, personal enhancement, status enhancement and targeted resource enhancement. The paper argues for the social policy of targeted resource enhancement for individuals with cognitive disabilities, in the form of providing cash with some limits on its use. Taking the example from the UK of ‘self-directed support’ it is argued that such policies can be cost-effective and advance the autonomy of people with cognitive disabilities, especially when compared with current policies of centrally provided services.

Robust technological enhancement of core cognitive capacities is now a realistic possibility. From the perspective of neutralism, the view that justifications for public policy should be neutral between reasonable conceptions of the good, only members of a subset of the ethical concerns serve as legitimate justifications for public policy regarding robust technological enhancement. This paper provides a framework for the legitimate use of ethical concerns in justifying public policy decisions regarding these enhancement technologies by evaluating the ethical concerns that arise in the context of testing such technologies on nonhuman animals. Traditional issues in bioethics, as well as novel concerns such as the possibility of moral status enhancement, are evaluated from the perspective of neutralism.

Cognitive enhancement takes many and diverse forms. Various methods of cognitive enhancement have implications for the near future. At the same time, these technologies raise a range of ethical issues. For example, they interact with notions of authenticity, the good life, and the role of medicine in our lives. Present and anticipated methods for cognitive enhancement also create challenges for public policy and regulation.
