 Some generalists, agreeing with particularists that moral knowledge presupposes a sensitivity to the moral landscape and skill in deploying what appear to be ceteris paribus laden principles, argue that such sensitivity and skill is possible only if the landscape itself is sufficiently patterned (McKeever and Ridge 2006) This argument is supposed to allow for holism about reasons, and so the relevant patterning consists in there being a finite number of considerations that can function as reasons, and that these can be affected by a finite number of enablers and defeaters operating in regular, “principled” ways. Particular pieces of moral knowledge, on this argument, presuppose only “default moral principles” which specify a feature which ground reasons, ceteris paribus. A full array of exceptionless principles, the argument continues, are presupposed by practical wisdom, characterized as including a capacity for reliably acquiring moral knowledge in a full range of novel circumstances.
