In a similar way, John Barrow uses the Anthropic Principle, not as an argument for design, but as a way of allowing biology to place constraints on physics (i.e., conditions that are required if the evolution of life is to be possible), and these constraints lead Barrow to the discovery of new explanations of hitherto disparate phenomena in physics. Such explanations seem like prime examples of what Murphy, using Lakatos, would call ‘novel facts,’ suggesting Barrow’s research program is progressive. See Barrow’s presentation and paper at the AAAS special conference, "Cosmic Questions", Spring, 1999 (to be published in 2000).
