ABSTRACT
This article explicates the unified argument of James G. Hart’s 1200 page work Who One Is. Hart begins with an exploration of the non-objective self as propertyless ipseity; then relates that sheer ipseity to the concrete development a self; and then, that self to the ideal self which guides its development; and finally, the ideal self to God as its origin. Hart also shows the relevance of Jaspers’ notion of Existenz at each of these stages. The uniqueness and “mineness” of any “I” cannot be a matter of properties. Each “I” is a unique “haecceity” for which multiple instantiation would be meaningless. Hart concludes with a fully developed theology of selfhood according to which God’s creation of the “haecceities” is an act of sheer generosity.
