This paper reviews the evolutionary history and biology of love and marriage. It examines the current and imminent possibilities of biological manipulation of lust, attraction and attachment, so called neuroenhancement of love. We examine the arguments for and against these biological interventions to influence love. We argue that biological interventions offer an important adjunct to psychosocial interventions, especially given the biological limitations inherent in human love.

Neuroscience has dramatically increased understanding of how mental states and processes are realized by the brain, thus opening doors for treating the multitude of ways in which minds become dysfunctional. This book explores questions such as when is it permissible to alter a person's memories, influence personality traits or read minds? What can neuroscience tell us about free will, self-control, self-deception and the foundations of morality? The view of neuroethics offered here argues that many of our new powers to read (...) ,alter and control minds are not entirely unparalleled with older ones. They have, however, expanded to include almost all our social, political and ethical decisions. Written primarily for graduate students, this book will appeal to anyone with an interest in the more philosophical and ethical aspects of the neurosciences. (shrink)

This volume collects a number of Perry's classic works on personal identity as well as four new pieces, 'The Two Faces of Identity', 'Persons and Information', 'Self-Notions and The Self' and 'The Sense of Identity'. Perry's Introduction puts his own work and that of others on the issues of identity and personal identity in the context of philosophical studies of mind and language over the past thirty years.

The prospects of enhancing cognitive or motor functions using neuroscience in otherwise healthy individuals has attracted considerable attention and interest in neuroethics (Farah et al., Nature Reviews Neuroscience 5:421–425, 2004; Glannon Journal of Medical Ethics 32:74–78, 2006). The use of stimulants is one of the areas which has propelled the discussion on the potential for neuroscience to yield cognition-enhancing products. However, we have found in our review of the literature that the paradigms used to discuss the non-medical use of stimulant (...) drugs prescribed for attention deficit/hyperactivity disorder (ADHD) vary considerably. In this brief communication, we identify three common paradigms—prescription drug abuse, cognitive enhancement, and lifestyle use of pharmaceuticals—and briefly highlight how divergences between paradigms create important “ethics blind spots”.

A person can be true to oneself even while transforming and even creating the person one is. One's self is not something merely waiting to be discovered, after all. To some extent, part of the human endeavor is deciding and trying to become who we want to be.

Reports in the popular press suggest that smart drugs or “nootropics” such as methylphenidate, modafinil and piracetam are increasingly being used by the healthy to augment cognitive ability. Although current nootropics offer only modest improvements in cognitive performance, it appears likely that more effective compounds will be developed in the future and that their off-label use will increase. One sphere in which the use of these drugs may be commonplace is by healthy students within academia. This article reviews the ethical (...) and pragmatic implications of nootropic use in academia by drawing parallels with issues relevant to the drugs in sport debate. It is often argued that performance-enhancing drugs should be prohibited because they create an uneven playing field. However, this appears dubious given that “unfair” advantages are already ubiquitous and generally tolerated by society. There are concerns that widespread use will indirectly coerce non-users also to employ nootropics in order to remain competitive. However, to restrict the autonomy of all people for fear that it may influence the actions of some is untenable. The use of potentially harmful drugs for the purposes of enhancement rather than treatment is often seen as unjustified, and libertarian approaches generally champion the rights of the individual in deciding if these risks are acceptable. Finally, whether the prohibition of nootropics can be effectively enforced is doubtful. As nootropics use becomes widespread among students in the future, discussion of this issue will become more pressing in the years to come. (shrink)

Advances in cognitive neuroscience make cosmetic neurology in some form inevitable and will give rise to extremely difficult ethical issuesConsider the following hypothetical case study. A well heeled executive walks into my cognitive neurology clinic because he is concerned that he is becoming forgetful. It turns out that he is going through a difficult divorce and my clinical impression is that his memory problems stem from the stress he is experiencing. I place him on a selective seratonin reuptake inhibitor, sertraline, (...) and in a few weeks he feels better. Around this time his 13 year old daughter has difficulty at school and is diagnosed by the school psychologist as having attention deficit disorder. I place her on adderall, a stimulant combination drug, which seems to help with her behaviour in school. My patient then comes to me because he is experiencing the “tip of the tongue” phenomena more frequently. He is concerned that his word finding difficulty interferes with his ability to function in high level meetings. I suggest we try a cholinesterase inhibitor to see if this helps. I am careful to explain that the Food and Drug Administration does not approve such a use for this medication. He wants to try it and is pleased with the results.A few months later, this patient visits me with his 16 year old son, a talented middle distance runner. His father thinks if he were just a bit better, among the elite high school runners in the state, he would be far more competitive as an applicant for selective colleges. We discuss various options. Because of a recent report that sildenafil, which is used conventionally for male impotence, may improve oxygen carrying capacity, I prescribe this medication. The son does not object.Encouraged by these pharmacologic successes, my patient …. (shrink)

Over the past decades, mood enhancement effects of various drugs and neuromodulation technologies have been proclaimed. If one day highly effective methods for significantly altering and elevating one’s mood are available, it is conceivable that the demand for them will be considerable. One urgent concern will then be what role physicians should play in providing such services. The concern can be extended from literature on controversial demands for aesthetic surgery. According to Margaret Little, physicians should be aware that certain aesthetic (...) enhancement requests reflect immoral social norms and ideals. By granting such requests, she argues, doctors render themselves complicit to a collective ‘evil’. In this paper, we wish to question the extent to which physicians, psychiatrists and/or neurosurgeons should play a role as ‘moral gatekeepers’ in dealing with suspect demands and norms underlying potential desires to alter one’s mood or character. We investigate and discuss the nature and limits of physician responsibilities in reference to various hypothetical and intuitively problematic mood enhancement requests. (shrink)
