"I sent to Rav Mazooz something from Rav Henkin's [Rav Yosef Eliyahu Henkin] newest volume in which He says that the Sephardim have something over us. They study dikduk and we all should study dikduk. And it's a problem and in the Ashkenaz world none of us study dikduk and we don't know dikduk and he has a whole piece there how important it is. Again showing Rav Henkin broke from the common way of thinking."
