Apparently, Francis Bacon once said, “A little philosophy makes men atheists: A great deal reconciles them to religion.” In his Natural History of Religion, David Hume explains how it works:

For men, being taught, by superstitious prejudices, to lay the stress on a wrong place; when that fails them, and they discover, by a little refection, that the course of nature is regular and uniform, their whole faith totters, and falls to ruin. But being taught, by more reflection, that this very regularity and uniformity is the strongest proof of design and of a supreme intelligence, they return to that belief, which they had deserted; and they are now able to establish it on a firmer and more durable foundation.

If nothing else, this makes a strong case for the need of Popper-style falsification.
