I
agree that what you are saying is a strategy open to the ethical
relativist. And it has the advantage, from my point of view, of
getting away from the search for "foundations" in normative
ethics. That's good as far as it goes.
But the attempt to find wide reflective equilibrium is still a
search for principles. It follows in the tradition of philosophers and
theologians who have tried to formulate moral "laws."
I think we should give up the search for principles and laws along
with the search for foundations. I say this for two reasons:
- Every principle or set of principles reflects the moral
experience of some group of people and ignores the moral
experience of others. In practice, this often means reflecting the
experience of some group of men and ignoring the experience of
most women.
- Every serious moral problem involves so many relevant variables
and is so thoroughly contextualized that we cannot formulate moral
principles that apply to it and to the other serious problems we
encounter.
The search for principles or laws is just as much an illusion --and
a dead end-- as the search for foundations. And it is especially
dangerous because it favors the interests of some groups over others.
Let's face reality and give it up. At least then we will be honest.
