  One might, in light of this, offer a more substantive principle, not as one that people actually all accept, but as one that they are all, in fact, committed to (though they may not realize it). This strategy offers the prospect of identifying a principle rich enough in content to serve as the justifying ground for other moral judgments. Yet it requires showing how the principle(s) identified work to justify the more specific judgments they are meant to support.  Moreover, one who takes this approach needs also to justify the claim that people are actually committed to the principle in the first place. And this raises the suspicion that claiming there are certain principles to which everyone is committed simply relocates the original challenge, without actually meeting it.
