The title of this volume by Masterson (emer., University College Dublin) is appropriately ambiguous. Is it God that one is approaching in philosophy and theology? Or merely discourses about ‘God’? According to Masterson, this ambiguity is necessary. To speak of God is always to speak about pre-philosophical experiences. And yet to speak of such experiences is to use the available philosophical (and/or theological) categories. Thus masterson’s book might be viewed primarily as a practice of metaphilosophy insofar as it attempts to think about the primary ways in which ‘God-talk’ occurs and the entailments regarding people’s models of God that such varying talk would yield. Suggesting that these primary ways are appropriately labeled ‘phenomenological,’ ‘metaphysical,’ and theological,’ Masterson offers sustained engagements with the representative figures for each approach: Jean-Luc Marion, Thomas Aquinas, and Karl Barth, respectively. The differences between these approaches are a matter of which first principles are in play in each: consciousness, being, and God. Ultimately, thought most of this volume is devoted to working through the differences between these approaches, the eventual, complementary account of how they must work together, given human limitations, is quite compelling. Summing Up: Recommended. Upper-level undergraduates through researchers/faculty.
