He was a famed Rosh Yeshivah of Volozhin, and a chavrusa of the Rogatchover Gaon, who changed the face of Torah learning. Indeed, the Rav (R’ Yosef Dov HaLevi Soloveitchik) said that if not for R’ Chaim’s sophisticated models of analysis, many intelligent Jews would have been lost to academia and the enlightenment. Chochmas HaTorah, the genius of Torah, was embodied in his unique methodology.
So, what do you think R’ Chaim asked a potential student who wanted to learn in Volozhin? It wasn’t like today. A student who wanted to learn in Volozhin was already a known genius and had probably learned all they could from other teachers and Yeshivas. They were coming to Oxford. They knew Shas. They knew how to learn. They were coming to hear the famed Shiurim of R’ Chaim or the Netziv.
R’ Chaim would ask them
If you had a third eye where would you place it
Most of the students would wriggle uncomfortably at the unexpected question and eventually say
I’d put the eye on the back of my head. My eyes see what’s in front of me, but if I put one behind me, I can see what is behind me as well
R’ Chaim replied:
No. You’d put the eye on your finger. That way, you could freely direct your eye in any direction and see everything
I don’t know about you, but I found this answer, and the question most profound!
