 Some opponents of contractualism will object that contractualism is not pluralist enough. They will object to the unified account of wrongness. Is it plausible that all the considerations relevant to what we owe to each other are unified by their relevance to whether the principle permitting the conduct could be reasonably rejected? In our moral deliberation about right and wrong actions, are all moral considerations only relevant in virtue of how they affect whether or not a principle licensing the proposed action is justifiable?
