Is this really me? Parasites and other humans’ cells in our brains change our psychology

Many people are suspicious about being manipulated in their emotions, thoughts or behaviour by external influences, may those be drugs or advertising. However, it seems that – unbeknown to most of us – within our own bodies exist a considerable number of foreign entities. These entities can change our psychology to a surprisingly large degree. And they pursue their own interests – which do not necessarily coincide with ours.

Effort, psychological continuity, human enhancement and superintelligence

One argument against human enhancement is that it is cheating. Cheating others and oneself. One may be cheating oneself for various reasons; because one took the easy path instead of actually acquiring a certain capacity, because once one enhances one is no longer oneself, because enhancements are superficial among others. I would like to try to develop further the intuition that “it is not the same person any more”. I will concentrate in forms of enhancement that involve less effort, are considered easier, or faster than conventional means because the cheating argument seems directed at them. In fact, most forms of non-conventional technological enhancements being proposed seem to be easier routes towards self-improvement. I will also explore how my considerations might mean trouble for any type of disruptive technology besides radical human enhancement, such as superintelligence or whole-brain emulation.

Dogs on drugs

drogs, by weegeeboredThat people in all cultures around the world use plant drugs to heal, intoxicate, or enhance themselves is well known. What is less well known – at least to me – is that many cultures give drugs to their dogs to improve hunting success. A new paper in Journal of Ethnopharmacology by B.D. Bennett and R. Alarcón reviews the plants used in lowland Ecuador, Peru and elsewhere.

They find a wide variety of drugs used. Some are clearly medicinal or just hide the dog’s scent. Others are intended as enhancers of night vision or smell. Some are psychoactive and intended to influence behaviour – make it walk straight, follow game tenaciously, be more alert, understand humans, or “not become a vagrant”. Several drugs are hallucinogenic, which may appear bizarre – how could that possibly help? The authors suggest that in the right dose they might create synaesthesia or other forms of altered perception that actually make the dogs better hunters by changing their sensory gating. Is drugging dogs OK? Continue reading

Why do we like our artist on drugs, but not our sportspeople?

inspiration-is-for-amateursThe internet and print media are happy to herald that movie director Lars Von Trier can’t work without alcohol. He reports that he tried to be sober and went to AA meetings for half a year, but has now started drinking again in order to be able to work. This is a victory for those who believe that artists are more creative on drugs. As Von Trier himself ranted late last year, before going in rehab, he thinks that going clean will probably mean the end of his career. He probably won’t be able to make movies at all, and what he will produce, will be ‘shitty’. ‘There is no creative expression of artistic value that has ever been produced by ex-drunkards and ex-drug-addicts. Who the hell would bother with a Rolling Stones without booze or with a Jimi Hendrix without heroin?’ He states that he wrote the screenplay for Dogville during a 12-day drug binge, but working on the screenplay for Nymphomaniac, while sober, took him 18 months.

Treatment for Crime Workshop (13th – 14th April) – Overview

Practical ethicists have become increasingly interested in the potential applications of neurointerventions—interventions that exert a direct biological effect on the brain. One application of these interventions that has particularly stimulated moral discussion is the potential use of these interventions to prevent recidivism amongst criminal offenders. To a limited extent, we are already on the path to using what can be described as neuro-interventions in this way. For instance, in certain jurisdictions drug-addicted offenders are required to take medications that are intended to attenuate their addictive desires. Furthermore, sex-offenders in certain jurisdictions may receive testosterone-lowering drugs (sometimes referred to as ‘chemical castration’) as a part of their criminal sentence, or as required by their conditions of parole.

On 13-14th April, a workshop (funded by the Wellcome Trust) focussing on the moral questions raised by the potential use of neuro-interventions to prevent criminal recidivism took place at Kellogg College in Oxford. I lack the space here to adequately explore the nuances of all of the talks in this workshop. Rather, in this post, I shall briefly explain some of the main themes and issues that were raised in the fruitful discussions that took place over the course of the workshop, and attempt to give readers at least a flavour of each of the talks given; I apologise in advance for the fact that I must necessarily gloss over a number of interesting details and arguments.

Editing the germline – a time for reason, not emotion

Gyngell, Douglas, Savulescu

There are rumours in the scientific community that the first studies involving the genetic modification of a human embryo are about to be published.[1] If true this would be the first case of an experiment in which genes in germ cells (sperm and egg cells) have been intentionally modified.  This has caused some concerns in the scientific community due to the fact that these modification are potentially heritable.  A commentary in Nature, (written by four leading scientists and one philosopher) published an appeal that we “Don’t edit the human germ line”.  Science meanwhile published a commentary which outlines “A prudent path forward for genomic engineering and germline gene modification”. The fact that two of the world’s most prestigious journals are publishing commentaries on human genetic modification shows just how powerful gene editing techniques have become. The rapid speed with which these technologies have developed has taken the scientific community, and everyone else, by surprise. Just three years after the DNA cutting nuclease Cas-9 was first used to modify DNA, scientists have been able to make heritable modifications to yeast, plants, mice, rats, pigs and even primates. It has been claimed that experiments conducted in China, currently under review, have used these same technologies to modify the DNA of human embryos.[2] Continue reading

Success, Self-esteem, and Human Enhancement

The philosopher turned theologian Jean Vanier was recently awarded the Templeton Prize for his work on behalf of the mentally disabled, and he spoke eloquently of the damage done to that group in particular by our culture of individual success.

Vanier’s point — that we judge people by what they do — is well taken, and it has some broad and important implications. Even those usually thought mentally and physically able may be unable to achieve enough to win the esteem of others, or to gain self-esteem. Of course, success has its benefits for those who succeed and often for others. But because of the close relation in our culture between self-esteem and accomplishment, many are left unsatisfied or even depresseed because of their ‘failure’.

Mind wars: do we want the enhanced military?

Jonathan Moreno presented a special lecture the 18th about “Mind Wars”, the military applications of neurotechnology. Here are some of my notes and comments inspired by this stimulating lecture. Continue reading

Smart pills vs. motivation pills – is one morally worse than the other?

Imagine a huge pile of unwashed dishes reminds you that you should clean your kitchen. Would you rather take a pill that increases your ability to clean very elaborately or one that helps you get off the couch and actually bring yourself to start cleaning? No hard decision for me…

Certain substances like methylphenidate can not only enhance cognition, but also motivation or, to be more precise, self-regulation. This is not too surprising as treating conditions associated with decreased self-regulation like ADHD often is a main purpose of such medication. Continue reading

Oxford Uehiro Prize in Practical Ethics: Is prohibition of breast implants a good way to undermine harmful and unequal social norms? by Jessica Laimann

This essay, by Oxford graduate student Jessica Laimann, is one of the two finalists in the graduate category of the inaugural Oxford Uehiro Prize in Practical Ethics. Jessica will be presenting this paper, along with three other finalists, at the 12th March final.

Is prohibition of breast implants a good way to undermine harmful and unequal social norms?


1           Introduction

Some individuals decide to inflict harm on themselves. Examples range from smoking or fasting, up to self-mutilation or suicide. In liberal moral theory, paternalistic interventions, that is, interventions with an individual’s choices for the individual’s own good, are considered prima facie morally wrong. Clare Chambers agrees with the liberal presumption against paternalism. However, she argues that some self-harming choices do permit interference due to the circumstances in which they occur. These are choices made in the context of unequal and harmful social norms, which fulfil the following three conditions (see Chambers 2008, 265):

  • The practice is significantly harmful to the individuals who engage in it.
  • Individuals engage in the practice in order to attain benefits which are norm-dependent – the benefits are linked to engagement in the practice only in virtue of social conventions.
  • The social norm that links the practice to the benefits undermines social or political equality.
