I did a liitle google for The Chosen Study Guide and got this:
After class, Rav Gershenson detains Reuven and asks him how his father might have resolved the passage’s contradictions. Reuven explains how his father would have reconstructed the text to make sense of it. Rav Gershenson is clearly impressed and praises both Reuven and his father. He says that he is not personally opposed to these controversial techniques but tells Reuven that he must never use them in his class. Afterward, Reuven looks for Rav Gershenson’s name in the school library’s card catalog, but does not find it. He realizes that Gershenson cannot publish, because if he expressed his belief in controversial Talmud scholarship, he would not be allowed to teach at the conservative college. Reuven realizes that his father’s controversial writings are the reason he is not teaching at Hirsch, even though he is a brilliant scholar.
