Logician, Don’t you think that reading comprehension is important to learning? In my experience it does not seem to require more than average intelligence (average for Ashkenazi Jews) to be successful in learning. What is required most is hasmoda and desire. Most of what is called “learning” is really nothing more than rote memory.
That is not to say that there aren’t true illuyim in the Beis Medrash but illuyis isn’t required for greatness in Torah. Many of our gedolim, past and present were not illuyim. They attained gadlus by dint of hard work and dedication.

It has already been long established that, when the tenor of the times requires it, women may be taught Torah (can you say “Beis Yaakov”?). As to the latter, why would a woman’s learning be less valuable or less worthy than her listening to shofar or benching esrog as mentioned previously. Here’s a thought. Since learning Torah is not a mitzvah shehazman grama, why wouldn’t a woman be just as mechuyiv in it as a man?
