Revised Oct 12, 2020 new addition at the end
About a year ago several people mentioned the book Breaking the Kuzari by Shraga Lowenstein. He tries to refute the Kuzari Principle which plays the key role in my argument that there is enough evidence to regard the revelation at Sinai as a real historical event. The book is long and very detailed - it represents a considerable serious effort to ,make the case. Nevertheless, he does not succeed. I originally planned a very detailed and complete reply. Since then other matters became more important. I hope the document linked below will be enough to convince the reader that Lowenstein's efforts are not fruitful. Should anyone read a section of his book that seems persuasive, write to me and I will try to add the reply to this document.
