 The Cross-Cultural Comparative Religious Ideas Project, run by Robert C. Neville and Wesley Wildman from 1995–99, balanced the overlap and difference when they concluded that an account of ultimacy should be a “properly vague” category: it needs enough shared content to count as a category, but enough vagueness to cover the disparate instances generally taken to be  ultimates.[5]  There are multiple contenders for such vague categories, including, e.g., Paul Tillich’s “object of ultimate concern” (1957a, e.g., 10–11), John Hick’s “the Real” (1989: 11ff); Keith Ward’s “the Transcendent” (1998); and the Project’s own proposal as “that which is most important to religious life because of the nature of reality” (Neville &amp; Wildman 2001, see 151ff for an explanation of each part of the phrase).
