In this paper, I aim to shed light on the phenomenon of moral deep disagreement by relating it not only to the notion of moral certainty but also to the concept of deep disruption as it is currently developed and discussed in the philosophy of technology. I argue that certainty, deep disagreement, and deep disruption are all located at the level of “bedrock practices” (Williams in Wittgenstein, mind and meaning, Routledge, Milton Park, 1999, p. 198), and that the fundamentality of their objects should be understood in terms of relationality and interconnectedness. Deep disagreements can occur through deep technology-induced disruption and can take the form of a disruption of deep conceptual agreement. Conceptual common ground can be re-established by continuous interaction and a collective process of moral articulation. Deep disruption and moral deep disagreement can lead to moral progress, for instance in the form of recognising and correcting an epistemic injustice.},

Wittgenstein’s On Certainty has been a source of inspiration for philosophers concerned with the notion of deep disagreement (see Fogelin in Informal Logic 25(1):3–11, 2005; Pritchard in Topoi 40:1117–1125, 2021. https://doi.org/10.1007/s11245-018-9612-y).
