To the extent that rule-consequentialism circumvents collapse, this theory is accused of incoherence. Rule-consequentialism is accused of incoherence for maintaining that an act can be morally permissible or even required though the act fails to maximise expected good. Behind this accusation must be the assumption that rule-consequentialism contains an overriding commitment to maximise the good. It is incoherent to have this overriding commitment and then to oppose an act required by the commitment. (For a recent developments of this line of thought, see Arneson 2005; Card 2007; Wall 2009.)
