R’ Kook was respected by the Chazon Ish
The Chazon Ish said that it is Assur to read R. Kook’s Hashkafa works although it is permitted to read his non-Hashkafic works. (Yalkut Daas Torah p.46)
Yoshe Ber Soloveitchik was respected by all the other gedolim of his time.
Rav Aharon Kotler ZTL, who would under no circumstances even walk into YU (even for a funeral), once commented about Rav Soloveitchik, “He is respnsible for the majority of Tumah in America.” Also from the same Rav Aharon, “He destroyed an entire generation of Jews.”
In the recently published “The Rav Thinking Aloud” by Rabbi David Holtzer, Rabbi YB Soloveichik tells – and this is on tape – about his meeting Rav Kook:
Someone asked Rabbi Soloveichik:
You felt the presence of greatness?
R. Soloveichik’s answer:
“I wouldn’t say greatness. Uniqueness. Greatness – if you understand by “greatness” intellectual greatness – no, I was not impressed by his scholastics.”
That entire paragraph (above is just the beginning) was met with such outrage by the religious Zionist community that in the next printing of the book, it was edited out. It’s not to be found.
They excised Rabbi Joseph B Soloveichik’s comments – as told to his Talmidim and recorded on tape (taped with permission, btw).
