The Bnei Torah know that the vast majority of everybody and anybody agrees with Rabbeinu Avraham. Actually, he is being very traditional. The truth is even more rationalistic than that. The reason why they don’t go around correcting the record, is because it confuses the masses. But the truth is that we can’t study The Torah properly with dogmatic or fundamentalistic views.
I wouldn’t post this so bluntly, but I was recently reading some blather from that fellow who fancies himself a rationalist. Nobody would be offended by my post. They would think I am from his crowd. But really it is opponents of that “rationalistic fellow” that are cut from the same cloth as him. Him and his opponents can’t think straight. The truth is, that The Torah was meant to be studies diligently. That is it’s only dogma. Pontificating about what Chazal may have known or not known about some scientific fact, is not diligent study. It is pure intellectual laziness. Learn the whole sugya from top to bottom and back, and then try to come up with a nafka mina al pi the scientific metzius. Until then, it really doesn’t matter. Obviously, it is just an out to avoid studying entire sugyos. The diligent students that leave the beis medrash because of some doubts, are only diligent in the non-Torah parts of their learning. Look closely and you will find it to be so.
