 Importantly, this common morality is historicist, in that its authority is established historically, through the success of its related norms in advancing human flourishing across time and place. However, unlike many historicist accounts, the common morality is not relativist, as its norms are to be applied universally. Beauchamp and Childress accord the common morality a special place within their approach, a place shielded from the jostling involved in the quest for coherence through wide reflective equilibrium. The common morality is thus the foundationalist aspect of their account. Moral conclusions, then, are justified through both coherence (via the method of reflective equilibrium), and through foundationalism, being connected to the principles of the common morality (Arras 2017: 23; Beauchamp &amp; Childress 2019b: 11).
