From the Theory Camp discussion of Charles Taylor's A Secular Age.
Charles Taylor spends much of the book considering the opposition between transcendental and immanent worldviews, which mostly boils down to Christianity vs. secular humanism. One of the most interesting points he makes is that we tend to choose these worldviews not because we are convinced by arguments for one side or the other. Instead, we are drawn to these positions for ethical reasons - what kind of life would I lead if I adopted one view or the other? What kind of life do people live who have already adopted one view or the other? We look at the narrative that each position would make in our lives. Then we consider arguments. And often we convince ourselves that the arguments were the reason we adopted the worldview in the first place.
One major story that atheists tell for being atheists is that "science disproves God." Really, though, Taylor argues, it is the moral authority of exclusive (atheistic) humanism that makes people think that they were made atheists by science. Science, by its very premises, could neither prove nor disprove God. The appealing atheist story is a narrative of coming of age, becoming mature.
