The distinction between philosophical theology and philosophy of religion is examined in relation to the role of faith commitments in each, and the notion of doctrinal statements as ‘truth claims’ is examined in terms whether ‘natural theology’ can legitimately be pursued. It is argued that the praeambula fidei version of this pursuit is illegitimate, partly because of the way in which ‘design’ arguments have often been overturned and partly because of the kinds of theological considerations put forward by Thomas Torrance and Alister McGrath. The relevance of Thomas Kuhn’s understanding of the scientific enterprise is also noted, especially in relation to his notion of paradigms.
