Keith Parsons on Tentative Science
"Is There a Case for Christian Theism?" in Does God Exist? (Buffalo, NY: Prometheus, 1991), p. 190.
Scientific hypotheses are always tentative; they are designed to be held only so long as they conform to the evidence. Proponents of the theistic hypothesis, on the other hand, are already sure that their hypothesis is correct; they only seek evidence to buttress a foregone conclusion.
