But what counts as a foundation? I'm willing to agree that there is no a priori 'proof' or scientific 'proof' of ethical principles. But is that the end of it? Perhaps there are still good reasons to accept certain ethical principles and reject others? In that sense, there may be foundations of a sort -- and perhaps some pretty good ones.

One possibility is that there are foundations in rational prudence. But that's not the only possibility. And while Dee thinks that foundations will lead to libertarian rights, that's not the only possibility either.

My main point is that just because certain kinds of foundations are not available, we shouldn't jump to some sort of moral skepticism and talk as though there are no foundations at all.
