Standard views about metaphysical structure presume that if metaphysical structure is hierarchical, any priority ordering of individuals is rigid or situationally invariant. This paper challenges this presumption. The challenge derives from an effort to interpret the kind of metaphysical structure implicit in writings central to the Huayan tradition of Chinese Buddhism. The Huayan tradition views reality as a realm of thoroughgoing interdependence. Close attention to primary sources indicates that this view does not fit comfortably in any of the metaphysical structures (...) familiar from contemporary analytic metaphysics. Accordingly, this paper also develops a conception of metaphysical structure that rejects the standard presumption. Motivation for this conception derives from attending to certain formal analogies between kinds of metaphysical structure and kinds of social organization. These analogies provide guidance for a conception of metaphysical structure as heterarchical or situationally variable. This conception breaks new ground for analytic metaphysics and opens conceptual space for interpreting Huayan metaphysics as a heterarchical variation of foundationalism. (shrink)
