First quote is actually more in reference to religious folk who take their personal belief - their personal, religious truth - into other domains, like science, where they are not appropriate. Second is sort of relevant to the first. If a religious person believes that god will protect them, then that is true for them, even if others may place a label like "delusion" on it. You and I see it differently, but because we would be evaluating that from a scientific/medical perspective. Do you see what I'm getting at?
