My last comment on this thread and I'm out.
I guess my use blind faith is redundant. Believing without reason/empirical evidence/experience.
I do not think one should be very possessive of a belief to the point where they say "nothing will change my mind." I do not think that one should base their life on principals/stories/adages/etc. without having said reason to do so based on empirical evidence/experience to do so. A good point I want to raise is that the vast majority of people practice the same faith as their parents. If you were born in Iran, you would most likely be Muslim. If you were born in Israel, you would most likely be Jewish.
There are definite times when we won't have previous experience or evidence to know how to approach a situation/problem/ethical situation/etc. This is where we have to draw on related experiences and make our best judgement to approach said situation. But I do not think it is wise to hold a strong belief unless you have a reason (empirical evidence/experience) to back it up. I hope this makes sense and answers what you were asking. But I have packing myself to do to move into my new place. Pleasure to discuss this with you, see you around on the forums.
