As with a historical name, it is useful... to distinguish between the available referent (our imaginative construct of God) and the real referent. The real referent for "God" is never accessible to us or in any way open to our observation or experience.... God is a symbol -- an imaginative construct -- that enables men to view the world and themselves in such a way as to make action and morality ultimately (metaphysically) meaningful. [85, 109]
