One idea is that the atheist in all his glory has a very limited knowledge, but bases his belief on that limited knowledge. Therefore, it is sort of an egotism about his superiority, which is a well known fault and goes back to the beginning of man according to the Bible. Likewise, as more is know in science, the greater the chance of understanding God. If that idea is accepted, the next thing is to review the early days of science and the conflicts with the Church and how that set into being the attitude of the academicians and their requirements into their church. From that, it should be obvious that non-believers are unsophisticated and their attitude is unworthy of the knowledge that they do have. The corruption is that most learned people who live off of their knowledge will never admit that they really don't know much.
