 The first claim of such accounts, then, is that there is some property of contemporary humans that is in some way descriptively or causally central to participating in their form of life.

Importantly, there is a step from the first to the second form of significance, and justification of the step requires argument. Even from a participant perspective, there is no automatic move from explanatory to normative significance.
