Philosophers of technology have identified various mechanisms through which technology can change moral norms, values, beliefs and practices. Danaher and Sætra (2023) offer a useful systematization of these mechanisms, with no claim to being exhaustive. We contribute to their work by analyzing how the mediating role of moral concepts fits into this scheme. First, we point out that concepts mediate the moral effects of technological changes, a process we call conceptual mediation. We illustrate this with the concepts of ‘brain death’ and ‘reproductive autonomy’, whose moral implications crystallized in the interplay with new medical technologies. Subsequently, we argue that conceptual mediation is best understood as a type of second-order mediation, which channels the moral implications of the first-order technological mediations identified by Danaher and Sætra (decisional, relational, perceptual). We conclude that second-order mediation plays a central and underappreciated role in processes of technomoral change.
