Amusing anecdote

I have a Chevrusa who told me an interesting story yesterday, one that I think is worth repeating. He learned at Rav Adin Steinsaltz's Yeshiva for several years. When my Chevrusa first heard about Mechkar, a method of study which involves looking at the different layers of editing in the Talmud and has its (modern) origins in academia, he was concerned that it might be heretical. When he asked Rav Steinsaltz, his Rosh Yeshiva, he got this response, "Any Apikorsus (heresy) that you can think of about the Talmud has already been explored by the Tosefos."
