What then is the secular ideal? The most important secular commitment is to the truth, which is based on observation and evidence rather than on mere faith. Seculars strive not to confuse truth with belief. If you have a very strong belief in some story, that may tell us a lot of interesting things about your psychology, about your childhood, and about your brain structure – but it does not prove that the story is true. (Often, strong beliefs are needed precisely when the story isn’t true.)
