PBA: I don’t know enough about Heshel to comment. I know the Frum philosophers don’t like him because they think he wasn’t Frum and the non-Frum philosophers don’t like him because they think he was. I do know, however, that Shaul Lieberman was Frum his entire life and was a tremendous Talmid Chacham who was well-respected by his peers, even if they strongly disagreed with his attempted Agunah solution.
