Not Too Risky. How to Take a Reasonable Stance on Human Enhancement

Following a trend in bioethical/applied ethics approaches, one of the frustrating features of studies on technological human enhancement is their dichotomous tendency. Often, benefits and risks of technological human enhancement are stated in theoretically and empirically vague, polarized, unweighted ways. This has blocked the debate in the problematic ‘pros vs. cons’ stage, leading to the adoption of extremist positions. In this paper, we will address one side of the problem: the focus on risks and the imprecise approach to them. What motivates our approach is the identification of the weaknesses of the anti-enhancement criticism, which stem from its use of the concept of risk, as well as the heuristic of fear and the precautionary principle. Thus, ‘taking a step back’ to move forward in the debate, our purpose is to establish some theoretical foundations concerning the concept of risk, recognizing, at the same time, its complexity and importance for the debate. Besides the concept of risk, we emphasize the concept of existential risk, and we make some considerations about epistemic challenges. Finally, we highlight central features of more promising approaches to move the debate forward. Keywords: Human enhancement technologies, risk, uncertainty, conceptual problem, epistemic challenges.
