The book explores the relationship between Christology and theological anthropology through the lens provided by the theology of Karl Barth and the mind/body discussion in contemporary philosophy of mind. It thus comprises two major sections. The first develops an understanding of Karl Barth's theological anthropology focusing on three major facets: (1) the centrality of Jesus Christ for any real understanding of human persons; (2) the resources that such a christologically determined view of human nature has for engaging in interdisciplinary discourse; and (3) the ontological implications of this approach for understanding the mind/body relationship. The second part draws on this theological foundation to consider the implications that Christological anthropology has for analyzing and assessing several prominent ways of explaining the mind/body relationship. Specifically, it interacts with two broad categories of theories: 'nonreductive' forms of physicalism and 'holistic' forms of dualism. After providing a basic summary of each, the book applies the insights gained from Barth's anthropology to ascertain the extent to which the two approaches may be considered christologically adequate.
