Barbour’s recent position has shifted from what it was in the 1960s, when in the context of two rival models (steady state and Big Bang) he stressed the neutrality of theology to such specific aspects of cosmology as t=0. In his 1990 Gifford Lectures he suggested that if a clear scientific consensus should emerge on the issue of t=0, it would be relevant to theology. Compare Ian Barbour, Issues in Science and Religion (New York: Harper & Row, 1966), 366-368; 377; 380; 414; 458 with Religion in an Age of Science, op. cit., 128-129.
