A problematic blindspot
Such an appeal to this notion of human is characteristic of the humanism of the modern era, opening with the Renaissance and marked by “an appeal to the essentially, universally human” grasped through a secular point of view emancipated from the authority of the Church and the aristocracy .Although it may be extremely easy to forget, as we are so used to manipulate the concepts of “human,” “human condition” or “human nature,” reference to a universal quality of humanness is fairly recent, tightly connected with 18th century’s political revolutions and the associated discourses about human rights .
But this notion of human remains ambiguous, to say the least. Beyond the clear common ground 19th century humanists share with “their conviction of the centrality of the ‘human’ itself” , the meaning of “human” remains controversial and multifaceted (one can for instance compare the French-style and political trend of humanism focusing upon freedom and the German-style philosophical insistence upon knowledge and understanding). Its most central components such as the focus put on the human individual, on human reason and on human freedom embed ambiguous consequences. Though they are clear factors of progress, they can also degenerate in threatening excesses. The focus upon the individual and its freedom can lead to individualism. The trust in human reason raises the risk of scientism when the limits and fallibility of human reason are obfuscated by its power and successes. Even the antagonism with the religious tradition hides many subtleties .
In addition, this humanism that is invoked to deal with ethical issues raised by NS and AI is not only an intrinsically problematic idea, it is also deeply disrupted by these knew knowledge and technologies. Is intelligence not one of the defining characteristics of humans? What becomes someone’s identity with respect to the technological possibilities of neuromodulation (up to the modification of subjects’ emotions and personality)? Are we just machines? Is it our fate to become obsolete and to clear the space for post-humans or artificial superintelligences? 
Here is a sample of issues clearly demonstrating that, if it is to be mobilized in AI and NS ethics, the notion of humanism needs further study. This indicates that our ability to frame AI and NS challenges also in ethical, moral and spiritual terms (our ability to build a collective ethical compass) is impeded by the lack of a shared, reliable and relevant understanding about humanism at the time of NS and AI. Despite the extreme variety and considerable scope of already existing efforts in AI and NS ethics, the topic of humanism itself remains a kind of blind spot that leaves concerned stakeholders largely under-equipped to steer societal development in the era of NS and AI. Their ethical capacity at participating to the regulation of NS and AI needs to be reinforced (ethical capacity-building*) through reflection upon and better understanding of humanism.
