Modern Halakhah for our time Book

Boy, Leibowitz is interesting. he's some kind of strange mix between Soloveitchik and Maimonides. His ideas about the halacha as an end in itself, the ideas the journey of halachic life, lishma, for it's own sake, flies in the face of so much of Western spiritual culture. I do like, however, that like Maimonides, and unlike say, Berkowits, his philosophy of God is totally rational--we can say nothing, there is nothing to say, end of discussion. Kant proved there's no way to prove or disprove God's existance, so Leibowitz doesn't twist himself into a pretzel, like Berkowits does, trying to prove the authenticity of the revelatory Torah. For Berkowits, everything about Jewish life is based upon the validity and historical truth of the Sinai encounter. For Leibowitz, it's all about man-made halacha. So awesome.
