Right, I absolutely agree with you. Like pretty much everything in life, we should take everything in moderation. I would argue that once logic fails, the only thing you have left is faith essentially. Let logic rule until it can't anymore, once that point is reached essentially only faith can replace it. No need to challenge existing and observable logic with faith.
And I've gotta disagree with the "when logic fails" part.
When logic fails, I don't rely on faith. I accept that I don't know what the heck's gonna happen, and I work with what I DO know and make educated guesses on what's gonna happen. Sometimes I'm right. Other times I'm wrong. And that's it. I don't believe that my beliefs affect reality around me in any way.
I'll use "reasoned confidence" over faith every time.
