Abstract
In this chapter, I consider the kinds of validity claims used in moral discourse—that is, what kinds of reasons we can offer when we are discussing what we ought to do in situations of disagreement and conflict. I suggest that the ones that are typically used in Western society, or that match our common sense in terms of the kinds of activities we undertake in discourse—claims about facts in the world, claims about what is normatively appropriate, and claims about the honesty of self-expressions—do not encompass the full range of possible validity claims available to us in principle or, in fact, those claims used in practice in societies other than Western ones. In particular, I suggest that some indigenous societies utilize at least one kind of validity claim that is not captured in this set, a claim that I call “ecological truth.”
