The very notion and prospect of human enhancement and related issues arouse public controversy.[88] Criticisms of transhumanism and its proposals take two main forms: those objecting to the likelihood of transhumanist goals being achieved (practical criticisms); and those objecting to the moral principles or world view sustaining transhumanist proposals or underlying transhumanism itself (ethical criticisms). However, these two strains sometimes converge and overlap, particularly when considering the ethics of changing human biology in the face of incomplete knowledge.

Critics or opponents often see transhumanists' goals as posing threats to human values.[89] Some also argue that strong advocacy of a transhumanist approach to improving the human condition might divert attention and resources from social solutions.[2] As most transhumanists support non-technological changes to society, such as the spread of civil rights and civil liberties,[citation needed] and most critics of transhumanism support technological advances in areas such as communications and health care,[citation needed] the difference is often a matter of emphasis. Sometimes, however, there are strong disagreements about the very principles involved, with divergent views on humanity, human nature, and the morality of transhumanist aspirations.[2] At least one public interest organization, the U.S.-based Center for Genetics and Society, was formed, in 2001, with the specific goal of opposing transhumanist agendas that involve transgenerational modification of human biology, such as full-term human cloning and germinal choice technology. The Institute on Biotechnology and the Human Future of the Chicago-Kent College of Law critically scrutinizes proposed applications of genetic and nanotechnologies to human biology in an academic setting.

Some of the most widely known critiques of the transhumanist program refer to novels and fictional films. These works of art, despite presenting imagined worlds rather than philosophical analyses, are used as touchstones for some of the more formal arguments.[2]

Feasibility
In a 1992 book, sociologist Max Dublin pointed to many past failed predictions of technological progress and argued that modern futurist predictions would prove similarly inaccurate. He also objected to what he saw as scientism, fanaticism, and nihilism by a few in advancing transhumanist causes, and said that historical parallels exised to millenarian religions and Communist doctrines.[90]

Although generally sympathetic to transhumanism, public health professor Gregory Stock is skeptical of the technical feasibility and mass appeal of the cyborgization of humanity predicted by Raymond Kurzweil, Hans Moravec and Kevin Warwick. He said that throughout the 21st century, many humans would find themselves deeply integrated into systems of machines, but would remain biological. Primary changes to their own form and character would arise not from cyberware but from the direct manipulation of their genetics, metabolism, and biochemistry.[91]

Those thinkers who defend the likelihood of accelerating change point to a past pattern of exponential increases in humanity's technological capacities. Kurzweil developed this position in his 2005 book, The Singularity Is Near.

Hubris
It has been argued that in transhumanist thought humans attempt to substitute themselves for God. This approach is exemplified by the 2002 Vatican statement Communion and Stewardship: Human Persons Created in the Image of God,[92] in which it is stated that, "Changing the genetic identity of man as a human person through the production of an infrahuman being is radically immoral", implying, as it would, that "man has full right of disposal over his own biological nature". At the same time, this statement argues that creation of a superhuman or spiritually superior being is "unthinkable", since true improvement can come only through religious experience and "realizing more fully the image of God". Christian theologians and lay activists of several churches and denominations have expressed similar objections to transhumanism and claimed that Christians attain in the afterlife what radical transhumanism promises, such as indefinite life extension or the abolition of suffering. In this view, transhumanism is just another representative of the long line of utopian movements which seek to create "heaven on earth".[93][94]



The biocomplexity spiral is a depiction of the multileveled complexity of organisms in their environments, which is seen by many critics as the ultimate obstacle to transhumanist ambition.
Another critique is aimed mainly at "algeny", which Jeremy Rifkin defined as "the upgrading of existing organisms and the design of wholly new ones with the intent of 'perfecting' their performance",[95] and, more specifically, attempts to pursue transhumanist goals by way of genetically modifying human embryos in order to create "designer babies". It emphasizes the issue of biocomplexity and the unpredictability of attempts to guide the development of products of biological evolution. This argument, elaborated in particular by the biologist Stuart Newman, is based on the recognition that the cloning and germline genetic engineering of animals are error-prone and inherently disruptive of embryonic development. Accordingly, so it is argued, it would create unacceptable risks to use such methods on human embryos. Performing experiments, particularly ones with permanent biological consequences, on developing humans, would thus be in violation of accepted principles governing research on human subjects (see the 1964 Declaration of Helsinki). Moreover, because improvements in experimental outcomes in one species are not automatically transferable to a new species without further experimentation, there is claimed to be no ethical route to genetic manipulation of humans at early developmental stages.[96]

As a practical matter, however, international protocols on human subject research may not present a legal obstacle to attempts by transhumanists and others to improve their offspring by germinal choice technology. According to legal scholar Kirsten Rabe Smolensky, existing laws would protect parents who choose to enhance their child's genome from future liability arising from adverse outcomes of the procedure.[97]

Religious thinkers allied with transhumanist goals, such as the theologians Ronald Cole-Turner and Ted Peters, reject the first argument, holding that the doctrine of "co-creation" provides an obligation to use genetic engineering to improve human biology.[98][99]

Transhumanists and other supporters of human genetic engineering do not dismiss the second argument out of hand, insofar as there is a high degree of uncertainty about the likely outcomes of genetic modification experiments in humans. However, bioethicist James Hughes suggests that one possible ethical route to the genetic manipulation of humans at early developmental stages is the building of computer models of the human genome, the proteins it specifies, and the tissue engineering he argues that it also codes for. With the exponential progress in bioinformatics, Hughes believes that a virtual model of genetic expression in the human body will not be far behind and that it will soon be possible to accelerate approval of genetic modifications by simulating their effects on virtual humans.[2] Public health professor Gregory Stock points to artificial chromosomes as an alleged safer alternative to existing genetic engineering techniques.[91] Transhumanists therefore argue that parents have a moral responsibility called procreative beneficence to make use of these methods, if and when they are shown to be reasonably safe and effective, to have the healthiest children possible. They add that this responsibility is a moral judgment best left to individual conscience rather than imposed by law, in all but extreme cases. In this context, the emphasis on freedom of choice is called procreative liberty.[2]

Contempt for the flesh
Philosopher Mary Midgley, in her 1992 book Science as Salvation, traces the notion of achieving immortality by transcendence of the material human body (echoed in the transhumanist tenet of mind uploading) to a group of male scientific thinkers of the early 20th century, including J.B.S. Haldane and members of his circle. She characterizes these ideas as "quasi-scientific dreams and prophesies" involving visions of escape from the body coupled with "self-indulgent, uncontrolled power-fantasies". Her argument focuses on what she perceives as the pseudoscientific speculations and irrational, fear-of-death-driven fantasies of these thinkers, their disregard for laymen, and the remoteness of their eschatological visions.[100]

What is perceived as contempt for the flesh in the writings of Marvin Minsky, Hans Moravec, and some transhumanists, has also been the target of other critics for what they claim to be an instrumental conception of the human body.[45] Reflecting a strain of feminist criticism of the transhumanist program, philosopher Susan Bordo points to "contemporary obsessions with slenderness, youth, and physical perfection", which she sees as affecting both men and women, but in distinct ways, as "the logical (if extreme) manifestations of anxieties and fantasies fostered by our culture."[101] Some critics question other social implications of the movement's focus on body modification. Political scientist Klaus-Gerd Giesen, in particular, has asserted that transhumanism's concentration on altering the human body represents the logical yet tragic consequence of atomized individualism and body commodification within a consumer culture.[66]

Nick Bostrom asserts that the desire to regain youth, specifically, and transcend the natural limitations of the human body, in general, is pan-cultural and pan-historical, and is therefore not uniquely tied to the culture of the 20th century. He argues that the transhumanist program is an attempt to channel that desire into a scientific project on par with the Human Genome Project and achieve humanity's oldest hope, rather than a puerile fantasy or social trend.[1]

Trivialization of human identity


In the US, the Amish are a religious group probably most known for their avoidance of certain modern technologies. Transhumanists draw a parallel by arguing that in the near-future there will probably be "Humanish", people who choose to "stay human" by not adopting human enhancement technologies, whose choice they believe must be respected and protected.[102]
In his 2003 book Enough: Staying Human in an Engineered Age, environmental ethicist Bill McKibben argued at length against many of the technologies that are postulated or supported by transhumanists, including germinal choice technology, nanomedicine and life extension strategies. He claims that it would be morally wrong for humans to tamper with fundamental aspects of themselves (or their children) in an attempt to overcome universal human limitations, such as vulnerability to aging, maximum life span, and biological constraints on physical and cognitive ability. Attempts to "improve" themselves through such manipulation would remove limitations that provide a necessary context for the experience of meaningful human choice. He claims that human lives would no longer seem meaningful in a world where such limitations could be overcome technologically. Even the goal of using germinal choice technology for clearly therapeutic purposes should be relinquished, since it would inevitably produce temptations to tamper with such things as cognitive capacities. He argues that it is possible for societies to benefit from renouncing particular technologies, using as examples Ming China, Tokugawa Japan and the contemporary Amish.[103]

Giuseppe Vattino, a supporter of transhumanism elected as a Member of Parliament in Italy, believes that although Transhumanism may make us less human, there are both positive and negative consequences. He believes that Transhumanism will make people “less subject to the whims of nature, such as illness or climate extremes”.[104]

Transhumanists and other supporters of technological alteration of human biology, such as science journalist Ronald Bailey, reject as extremely subjective the claim that life would be experienced as meaningless if some human limitations are overcome with enhancement technologies. They argue that these technologies will not remove the bulk of the individual and social challenges humanity faces. They suggest that a person with greater abilities would tackle more advanced and difficult projects and continue to find meaning in the struggle to achieve excellence. Bailey also claims that McKibben's historical examples are flawed, and support different conclusions when studied more closely.[105] For example, few groups are more cautious than the Amish about embracing new technologies, but though they shun television and use horses and buggies, some are welcoming the possibilities of gene therapy since inbreeding has afflicted them with a number of rare genetic diseases.[91]

Genetic divide
Some critics of libertarian transhumanism have focused on its likely socioeconomic consequences in societies in which divisions between rich and poor are on the rise. Bill McKibben, for example, suggests that emerging human enhancement technologies would be disproportionately available to those with greater financial resources, thereby exacerbating the gap between rich and poor and creating a "genetic divide".[103] Lee M. Silver, a biologist and science writer who coined the term "reprogenetics" and supports its applications, has nonetheless expressed concern that these methods could create a two-tiered society of genetically engineered "haves" and "have nots" if social democratic reforms lag behind implementation of enhancement technologies.[106] Critics who make these arguments do not thereby necessarily accept the transhumanist assumption that human enhancement is a positive value; in their view, it should be discouraged, or even banned, because it could confer additional power upon the already powerful. The 1997 film Gattaca's depiction of a dystopian society in which one's social class depends entirely on genetic modifications is often cited by critics in support of these views.[2]

These criticisms are also voiced by non-libertarian transhumanist advocates, especially self-described democratic transhumanists, who believe that the majority of current or future social and environmental issues (such as unemployment and resource depletion) need to be addressed by a combination of political and technological solutions (such as a guaranteed minimum income and alternative technology). Therefore, on the specific issue of an emerging genetic divide due to unequal access to human enhancement technologies, bioethicist James Hughes, in his 2004 book Citizen Cyborg: Why Democratic Societies Must Respond to the Redesigned Human of the Future, argues that progressives or, more precisely, techno-progressives must articulate and implement public policies (such as a universal health care voucher system that covers human enhancement technologies) in order to attenuate this problem as much as possible, rather than trying to ban human enhancement technologies. The latter, he argues, might actually worsen the problem by making these technologies unsafe or available only to the wealthy on the local black market or in countries where such a ban is not enforced.[2]

Threats to morality and democracy
Various arguments have been made to the effect that a society that adopts human enhancement technologies may come to resemble the dystopia depicted in the 1932 novel Brave New World by Aldous Huxley. Sometimes, as in the writings of Leon Kass, the fear is that various institutions and practices judged as fundamental to civilized society would be damaged or destroyed.[107] In his 2002 book Our Posthuman Future and in a 2004 Foreign Policy magazine article, political economist and philosopher Francis Fukuyama designates transhumanism the world's most dangerous idea because he believes that it may undermine the egalitarian ideals of democracy in general and liberal democracy in particular, through a fundamental alteration of "human nature".[5] Social philosopher Jürgen Habermas makes a similar argument in his 2003 book The Future of Human Nature, in which he asserts that moral autonomy depends on not being subject to another's unilaterally imposed specifications. Habermas thus suggests that the human "species ethic" would be undermined by embryo-stage genetic alteration.[108] Critics such as Kass, Fukuyama, and a variety of authors hold that attempts to significantly alter human biology are not only inherently immoral but also threaten the social order. Alternatively, they argue that implementation of such technologies would likely lead to the "naturalizing" of social hierarchies or place new means of control in the hands of totalitarian regimes. The AI pioneer Joseph Weizenbaum criticizes what he sees as misanthropic tendencies in the language and ideas of some of his colleagues, in particular Marvin Minsky and Hans Moravec, which, by devaluing the human organism per se, promotes a discourse that enables divisive and undemocratic social policies.[109][citation needed]

In a 2004 article in the libertarian monthly Reason, science journalist Ronald Bailey has contested the assertions of Fukuyama by arguing that political equality has never rested on the facts of human biology. He asserts that liberalism was founded not on the proposition of effective equality of human beings, or de facto equality, but on the assertion of an equality in political rights and before the law, or de jure equality. Bailey asserts that the products of genetic engineering may well ameliorate rather than exacerbate human inequality, giving to the many what were once the privileges of the few. Moreover, he argues, "the crowning achievement of the Enlightenment is the principle of tolerance". In fact, he argues, political liberalism is already the solution to the issue of human and posthuman rights since, in liberal societies, the law is meant to apply equally to all, no matter how rich or poor, powerful or powerless, educated or ignorant, enhanced or unenhanced.[6] Other thinkers who are sympathetic to transhumanist ideas, such as philosopher Russell Blackford, have also objected to the appeal to tradition, and what they see as alarmism, involved in Brave New World-type arguments.[110]

Dehumanization
Biopolitical activist Jeremy Rifkin and biologist Stuart Newman accept that biotechnology has the power to make profound changes in organismal identity. They argue against the genetic engineering of human beings, because they fear the blurring of the boundary between human and artifact.[96][111] Philosopher Keekok Lee sees such developments as part of an accelerating trend in modernization in which technology has been used to transform the "natural" into the "artifactual".[112] In the extreme, this could lead to the manufacturing and enslavement of "monsters" such as human clones, human-animal chimeras or bioroids, but even lesser dislocations of humans and non-humans from social and ecological systems are seen as problematic. The film Blade Runner (1982), the novels The Boys From Brazil (1978) and The Island of Dr. Moreau (1896) depict elements of such scenarios, but Mary Shelley's 1818 novel Frankenstein is most often alluded to by critics who suggest that biotechnologies could create objectified and socially unmoored people and subhumans. Such critics propose that strict measures be implemented to prevent what they portray as dehumanizing possibilities from ever happening, usually in the form of an international ban on human genetic engineering.[113]

Others believe that “we are morally obligated to help the human race transcend its biological limits.”[114] In fact, they go so far as to call those who are opposed to them, “Bio-Luddites.”[114] Though the gamut of Transhumanist opinions ranges from those who believe that we will eventually be cyborgs to those who simply want their brains frozen in the hopes of being resuscitated in the future, all have considered the question of the human identity, and whether or not it will be compromised. While the concept of being able to do away with negative emotions is appealing in theory, there are possible negative implications. For example, Francis Fukuyama, a political scientist, points out that if we did not have the emotion of aggression, “we wouldn’t be able to defend ourselves.”[114] These would not only affect our humanity, but also our interactions with others.[114]

Writing in Reason magazine, Ronald Bailey has accused opponents of research involving the modification of animals as indulging in alarmism when they speculate about the creation of subhuman creatures with human-like intelligence and brains resembling those of Homo sapiens. Bailey insists that the aim of conducting research on animals is simply to produce human health care benefits.[115]

A different response comes from transhumanist personhood theorists who object to what they characterize as the anthropomorphobia fueling some criticisms of this research, which science fiction writer Isaac Asimov termed the "Frankenstein complex". They argue that, provided they are self-aware, human clones, human-animal chimeras and uplifted animals would all be unique persons deserving of respect, dignity, rights and citizenship. They conclude that the coming ethical issue is not the creation of so-called monsters but what they characterize as the "yuck factor" and "human-racism" that would judge and treat these creations as monstrous.[27][116]

Specter of coercive eugenicism
Some critics of transhumanism allege an ableist bias in the use of such concepts as "limitations", "enhancement" and "improvement". Some even see the old eugenics, social Darwinist and master race ideologies and programs of the past as warnings of what the promotion of eugenic enhancement technologies might unintentionally encourage. Some fear future "eugenics wars" as the worst-case scenario: the return of coercive state-sponsored genetic discrimination and human rights violations such as compulsory sterilization of persons with genetic defects, the killing of the institutionalized and, specifically, segregation from, and genocide of, "races" perceived as inferior.[117] Health law professor George Annas and technology law professor Lori Andrews are prominent advocates of the position that the use of these technologies could lead to such human-posthuman caste warfare.[113][118]

For most of its history, eugenics has manifested itself as a movement to sterilize the "genetically unfit" against their will and encourage the selective breeding of the genetically fit. The major transhumanist organizations strongly condemn the coercion involved in such policies and reject the racist and classist assumptions on which they were based, along with the pseudoscientific notions that eugenic improvements could be accomplished in a practically meaningful time frame through selective human breeding.[118] Most transhumanist thinkers instead advocate a "new eugenics", a form of egalitarian liberal eugenics.[119] In their 2000 book From Chance to Choice: Genetics and Justice, (non-transhumanist) bioethicists Allen Buchanan, Dan Brock, Norman Daniels and Daniel Wikler have argued that liberal societies have an obligation to encourage as wide an adoption of eugenic enhancement technologies as possible (so long as such policies do not infringe on individuals' reproductive rights or exert undue pressures on prospective parents to use these technologies) in order to maximize public health and minimize the inequalities that may result from both natural genetic endowments and unequal access to genetic enhancements.[120] Most transhumanists holding similar views nonetheless distance themselves from the term "eugenics" (preferring "germinal choice" or "reprogenetics")[106] to avoid having their position confused with the discredited theories and practices of early-20th-century eugenic movements.[121]

Existential risks
Struck by a passage from Unabomber Theodore Kaczynski's anarcho-primitivist manifesto (quoted in Kurzweil's 1999 book, The Age of Spiritual Machines[16]), computer scientist Bill Joy became a notable critic of emerging technologies.[122] Joy's 2000 essay "Why the future doesn't need us" argues that human beings would likely guarantee their own extinction by developing the technologies favored by transhumanists. It invokes, for example, the "grey goo scenario" where out-of-control self-replicating nanorobots could consume entire ecosystems, resulting in global ecophagy.[123] Joy's warning was seized upon by appropriate technology organizations such as the ETC Group. Related notions were also voiced by self-described neo-luddite Kalle Lasn, a culture jammer who co-authored a 2001 spoof of Donna Haraway's 1985 Cyborg Manifesto as a critique of the techno-utopianism he interpreted it as promoting.[124] Lasn argues that high technology development should be completely relinquished since it inevitably serves corporate interests with devastating consequences on society and the environment.[125]

In his 2003 book Our Final Hour, British Astronomer Royal Martin Rees argues that advanced science and technology bring as much risk of disaster as opportunity for progress. However, Rees does not advocate a halt to scientific activity; he calls for tighter security and perhaps an end to traditional scientific openness.[126] Advocates of the precautionary principle, such as many in the environmental movement, also favor slow, careful progress or a halt in potentially dangerous areas. Some precautionists believe that artificial intelligence and robotics present possibilities of alternative forms of cognition that may threaten human life.[127] The Terminator franchise's doomsday depiction of the emergence of an A.I. that becomes a superintelligence - Skynet, a malignant computer network which initiates a nuclear war in order to exterminate the human species, has often been cited by some involved in this debate.[128]

Transhumanists do not necessarily rule out specific restrictions on emerging technologies so as to lessen the prospect of existential risk. Generally, however, they counter that proposals based on the precautionary principle are often unrealistic and sometimes even counter-productive, as opposed to the technogaian current of transhumanism which they claim is both realistic and productive. In his television series Connections, science historian James Burke dissects several views on technological change, including precautionism and the restriction of open inquiry. Burke questions the practicality of some of these views, but concludes that maintaining the status quo of inquiry and development poses hazards of its own, such as a disorienting rate of change and the depletion of our planet's resources. The common transhumanist position is a pragmatic one where society takes deliberate action to ensure the early arrival of the benefits of safe, clean, alternative technology rather than fostering what it considers to be anti-scientific views and technophobia.[129]

One transhumanist solution proposed by Nick Bostrom is differential technological development, in which attempts would be made to influence the sequence in which technologies developed. In this approach, planners would strive to retard the development of possibly harmful technologies and their applications, while accelerating the development of likely beneficial technologies, especially those that offer protection against the harmful effects of others.[49] An argument for an "anti-progressionist and pessimistic version of transhumanism" has also been presented by Philippe Verdoux.[130]
