It's not religion versus science, or faith versus reason, or hope versus despair, or order versus chaos. We walk along a knife's edge between certainty and doubt. At a pathological extreme, it is between mania and depression. Faith is not about god or reason, but the necessary idea that we can -- and ought to -- maintain our balance as we continue forward. Whether it derives from religion or science or art or community doesn't matter; each of those is only as good as the persons who make it up. Each is equally subject to certainty and doubt. The difference between religion and science is in the former tending too often toward certainty and the latter too often toward doubt. Life "without god" isn't any harder than life "with god". In fact, they are not different.
