Faith

There's a reason for faith commonly under-appreciated:

We humans can't function without faith. We know nothing without faith. When we bark our shins we're showing faith in our sensory system: faith that the pain in our leg represents contact with a physical universe. We don't know anything without faith.

Faith can be overdone. Witness St. Paul.

Which brings me to my point: humans use faith to displace whatever they want displaced: experience, reason, logic ... Faith can substitute for any of them. Schools, churches, media ... dispense faith.

A gallimaufry of examples may be the least misleading (just a couple to start):
We drop bombs on people. Common logic would indicate that that's bad, but no: with faith, we can see that that's how Americans help people. Americans are helpful. Isn't that what the papers say?

We murder Christ, drink his blood, eat his flesh. You'd think we're murderers, deicides, vampires, cannibals; no, with faith it proves that we're saved, God's Chosen.

We just lost nine bets in a row at the track. You might think that that means that gambling is for fools. No, with faith, it proves that we'll hit the jackpot next time.
