Ah, well in a hope to move this discussion along, perhaps you would be so kind as to submit something in which you have faith, in which you do not also have observational experience.
You can't possibly be that thick. Use the example I already gave. Based on experience and trial / error I have faith my friend will respond to a text of mine.
We can go bigger and say I have faith that objective reality exists based on extensive experience. However, it's never going to be a certainty, as you know if you've spent 5 seconds of your life studying knowledge. To not have faith in it would render life impossible though, stuck in a realm of absolute skepticism with no hope of any sense.
