A Reply to Mark Frank
This reply is too long to put in the comments section to the previous post, so I am making a new post.

BarryA replies: It depends on what you mean by “faith.” The first entry in the American Heritage Dictionary is what I mean: “Confident belief in the truth, value, or trustworthiness of a person, idea, or thing.”
Take your example. Yes, it is true that you don’t accept 2+2=4 on faith. But back up a couple of steps and you’ll find faith at a deeper level. You believe this mathematical formula is true, because you believe in the law of non-contradiction, which in turn means you believe we live in a non-chaotic universe in which there is meaning and in which logic prevails. You believe this not because you can demonstrate it to be true (Popper says, correctly I think, that universal statements can never be verified), but because you have a confident belief that it is true – i.e., you believe it on faith.
