It sounds as if you are saying there is no rational reason for you to take the rationalist approach but that is your choice. However, I also get the sense from your well reasoned arguments - especially in the "Challenge of Creation" - that your beliefs go beyond a chocolate/vanilla dichotomy. Could you clarify? Isn't the choice between Charedi and CO or MO more than just a predilection for a certain kind of community? You say that you can not think of an objective method to determine which way is correct. However, in you other writings you argue convincingly that that there is such a method: the responsible use of one's sense and intellect. Perhaps I am misunderstanding you.
The sentence in my essay to which you referred was one that I didn't write it precisely enough, but what I meant was specifically in reference to whether we should view God as using miracles or not, I can't see how to objectively determine this.
You write that you prefer the rationalist approach. Isn't more than "prefer"? Don't you really believe it to be true and the other approach untrue? I know it can't be proven. Many things can't be proven, including G-d. But you and I still believe G-d exists. We don't simply prefer the claims that He exists.
Yes, I believe it to be true. I think that many aspects of it can even be proven (at least to my own satisfaction!)
You write that the non-rationalist approach is good for many people. I understand where you're coming from, but can a society based on untruths really be okay in your mind? Believing that maggots grow spontaneously may result in a wonderful mode of life, but it is untrue. Do you feel comfortable saying that a society based on untruth is perfectly fine (however great the society is)?
I know some of the medieval rabbis (and Plato etc.) believed the masses can and should believe untruths. Is that your position as well? I understand this position, but I am slightly uncomfortable with it. You, on the other hand, seem to be sanguine about it.
I really am fine with the masses believing untruths. The question of whether an entire community should be this way is slightly more complicated; I am a little bothered by whether those individuals who are truth-seekers have a way to find the right niche for themselves, and by the fact that spiritual leaders may be insufficiently educated in theology etc. But every society has its problems and drawbacks; in light of this, overall I am still basically comfortable with the existence of such societies.
