Faith of some form is absolutely required. The alternative is to apply doubt to absolutely everything. I have some experience with this. At some point, some form of faith must be applied to keep all the questions from unravelling everything.

It’s like pulling a loose thread, except that each meme is tied many other memes, and the unraveling allows further unravelling until it exceeds the mind’s ability to process.

Some form of faith acts as a glue to hold the whole thing together, and give it some solidity, some basis for which to form patterns.

… and then, for any faith, there will be the zealots. I think that a combination of being Human and social Individuation. I think that Individuation is probably too deeply rooted in biology (down to the cell level) to be eliminated except through total eradication.
