Referring mostly to your other post quoting mine, I don't see how a lack of something can inform you about anything, unless you also stipulate that faith actually is also informing you. I don't see how a 'lack of faith' can focus on anything because it is the absence of something (state of being, point of view, whatever).
A lack of faith can inform a lack of confidence, such as my lack of confidence that there's some invisible, intelligent force trying to make the universe a better place. This informs my conclusion that if I want the universe to be a better place, I'd better get on the task myself.
... that or a lack of confidence that "I" will survive the death of my physical body, which informs my conclusion that I shouldn't waste the time I have.
I hardly think you can make that conclusion logically. :sarcastic At the most you can say that you believe faith is irrelevant to your life, but then to make that statement logically you'd have to compare 0.9 penguin with faith to 0.9 without faith.
Even if we found that 0.9 without faith really is a better person that 0.9 with faith, you can't extend your conclusion to luna with or without faith.
I don't know about that. We're both people, so presumably (hopefully) we share some commonality of experience. At the very least, together, we're a statistical sample that can be used to make inferences... and while a sample size of two would have a very large variance, it's still much more likely to be reflective of the "big picture" than a sample size of one.
