More thoughts: here are some potential problems with and objections to transhumanism, to begin with in the broadest sense of the theory advocating the achievement of human progress through technology. These potential criticisms, which occur to me at this moment, will not apply to all or every example of approaches termed transhumanist (which would include a rather disparate grouping, as I have said), but I think they are worth considering in any particular approach.
• Adherence to a sort of historical materialism, or modelling progress through a material, teleological historicism, despite historical discreditation of other forms of this by counterexamples — historical developments more easily explained otherwise (for example by principles of unique events, by the internalized influence of various ideas in a culture or individual, by biological commonalities in human nature, by mysterious individual faculty or creativity, etc.). In this sense transhumanism could be seen as undue simplification of more complex factors, not reducible to the products of technological capacities.
• Continuing from the above, determinism following from a faith in the advantageous or productive ramifications of developments in technology to improve human life, but minimization of possible deleterious or tangential ramifications. Such focus on technological benefits appears unwarranted unless coupled with a more sophisticated theoretical basis, which might account for why so many inventions and refinements have a) either been deliberately harnessed to achieve goals contrary to human advancement (e.g. much targeted DoD funding for the science and engineering towards military applications), or b) brought benefits coupled with unforeseen consequences which amounted to the same problem (e.g.
Fritz Haber's chemistry), or c) brought unexpected benefits exceeding their original design (e.g. the internet, originally an academia-military partnership).
• Continuing from that point, failure to acknowledge the problem of dystopia in all its magnitude, and relationship to powerful technologies for the fullest realization of any attempted utopian (really dystopian) society.
• That various schools of transhumanism differ extraordinarily in philosophical methods, aims, and strategies, including both democratic socialism and liebrtarianism under the same roof of technological affinity and belief and faith, even to the point of something like worship of technological promise.
• Not unrelated to that, an ill-defined idea of human progress, happiness, satisfaction, etc. Individual or collective? physical or mental? human or non-human? productive or post-economic? and many other sometimes false, sometimes deep dilemmas of definition become points of argument.
• At the same time an interest in very simplified definitions of progress or improvement, such as enhanced physical strength, IQ, etc., each of which might be critiqued as less advantageous and more superficial than other forms of personal development. Briefly, IQ tests are stupidly overemphasized in themselves as though we had no knowledge of multiple, and non-quantifiable intelligences. Also physical strength historically better equips people to become slaves, servants and soldiers under the power of those less mighty. There is little reason to think that these or other cyber/genetic or other isolated, superficial enhancements to specific, quantifiable capacities would empower individuals to live better lives any more than they have in the past, without integrated and cohesive personality development, liberating systems of philosophical principles, and varied, useful models of analysis and conception — in short complicated enhancements which are not obviously or mainly technological products.
• Likewise a poor track record of technological fields of development to affect direct enhancements. While economic productivity has often resulted from technological enhancements, given a social and cultural foundation willing and able to appreciate, generate, reward, and circulate them, direct biological or artificial modification of human beings to "improve" them, or in fact change them in any substantive way, really has not materialized. Promises of cyber- and nano- enhancements are still too premature to judge. Genetics were found to be a much more limited field than once thought, due to the limited numbers of genes discovered (most of the complexity of form is found in phenotypical protein expression, which is a recombination of billions of proteins from mere thousands of genes). Genetic determinism is fairly discredited outside of certain studies of rare diseases and counterfactual scenarios like "Gattaca." There is little reason to imagine positive enhancements will not imitate our generally unsatisfying experience trying to address troublesome polycausal phenomena such as cancer using genetic analysis. And judging from complex system neuroscience, the most important thing to enhance (the central nervous system) may well defy any attempt for direct modification by a linear or determinist model of change. There is little if any reason to think our modern tech will in the forseeable future be able to help us much with the real development except in the most secondary way, in the service of those same disciplines which predate it and have already been guiding personal and inner development for centuries or thousands of years: 'metaphysical' visualization through metaphor and myth, psychological models of analysis and guided development, philosophical modelling using verbal and other interpretation, and so on.
• Following the above up, transhumanists often may fail to appreciate the extent and depth of the biological human being they attempt to change. Should a change actually be affected, they do not and often cannot know whether the results of a direct change to one or a few variables would be desired ones, given that a human being is a complex system of complex systems, which are by definition unpredictable, or predictable within rather severe confines. A great deal of the human equation involves the massive influence of many thousands of years of culture we still understand poorly, and much more so the innate biological past of millions and even billions of years of the history of our ancestral organisms. Even if some understand a bit of this influence and profound legacy within ourselves, and are able to appreciate some of the limitations of this biological mortmain, controlling it is a whole other problem beyond knowing a problem exists or describing it. Further, if our characteristics inherently involve "primitive" older circuits, hopefully recombined in interesting and sophisticated ways, it's not clear that human progress would involve speaking a new and foreign 'language' of technologically-driven development, a magic with supposedly superior efficacy for change, to the exclusion of better understanding and conjuring up the old tongue of evolutionary development (whether bodily, behaviorally, conceptually — this is organic in nature, first and foremost) which actually has delivered our tangible and intangible advancements, including the abilities necessary to create and harness artifices (i.e. technology).
• In conclusion of some of the points above, an overemphasis of technology contra other models which may better predict and achieve human development, chiefly philosophical development and the nature of predominant ideological rules.
• Finally, transhumanism often appears an attempt to take shortcuts around more difficult and yet more important work to understand, define, and affect the advancement of life. Technology often seems more impressive than its subtler relatives in other fields among our more intangible toolboxes, intellectual, philosophical, psychological, and other disciplines. Nonetheless it has not proven itself to wholly exceed the profoundness of other tools, and rather has shown that like all other tools, it loses it relevance or even oversteps its bounds dangerously when applied haphazardly in contexts beyond its sensible application.
Any thoughts on these points I have sketched out, anyone?
Also any notion of whether this sort of discussion should be further refined and published? I'm curious to hear how important you think it is to address this stuff more formally.
Incidentally I could come up with some endorsements too, but I feel more of a need to address the headlong, surface-skimming optimism among many transhumanists who have beaten me to the enthusiastic position. I think there's probably enough heedless faith in technology around — and I by no means oppose exploring and utilizing technology. I depend on it every day. However I also feel it causing me trouble every day (RSI/carpal tunnel is a handy reality check, no pun intended).
EDIT: fixed typos and added more.
