My answers to a couple of comments on this post -
I wasn't trying to give you a hard time for posting anonymously - sorry if it came across that way.
You're right - perhaps the word "retreat" is a poor choice. But I do not believe in rejecting empirical evidence because my religion claims it must be wrong. If I had always lived in caves and my religion had taught me that the sky was green, and I had always believed that, what would happen if I came to the surface and saw that the sky was blue? There would be 3 choices.
1) The sky isn't blue, despite the evidence of my own eyes.
2) The sky is green; therefore, my entire religion is wrong.
3) The sky is green, therefore my religion was wrong about this particular point. That doesn't invalidate the rest of the religion.
My beliefs would fall into the 3rd category. I love Hashem, I love Judaism. I am forced to concede that Judaism had it wrong on some counts, but that doesn't mean I reject it all.
You say that science is accelerating. But it cannot disprove an intangible. Science can never disprove my belief in God. Nor can science disprove that the Torah is, at the very least, divinely inspired by God and that there was some sort of revelation. This holds true even if the Torah was written by humans at a later date than is traditionally believed. If I choose to believe that many of the historical events and characters in the Torah are "true" only symbolically or allegorically, science cannot disprove that.
So, in answer to your question on what I believe that cannot be changed by scientific evidence: I believe in God and that the Torah is divinely inspired and that Judaism is an outgrowth of that Torah. I believe I am bound by the halachic system because we were commanded by God to create a process based on his revelation that resulted in said system of laws.
None of this can be disproved by science, so I am confident that I never need give up my basic beliefs.
I'm actually not really struggling with the conflict between science & Torah. I'm pretty comfortable with the middle ground that I carved out. I am fascinated by the challenges and possible solutions, but I don't feel my basic belief system is in danger.
