This discussion note offers a preliminary analysis of what recent developments in human germline gene editing tell us about the effectiveness of speculative and anticipatory modes of techno-ethics. It argues that the benefits of speculative discussions are difficult to detect thus far, and that pushing the focal point of ethical discourse well ahead of the current state of technology may prematurely undermine existing norms long before a broad consensus would justify moving beyond them.

This paper seeks to develop a theory of health that aligns with the shift in contemporary medical practice and research toward a temporally extended epidemiological view of health. The paper describes how such a theory is at the core of life course based approaches to health, and finds theoretical grounding in recent work in the philosophy of biology promulgating a process theory of life.
