" was Judaism a part of life, or the whole of it? If it was only a part, then a compromise with modernity was possible. But in that case the Jews might simply fade into the majority societies around them. If it was the whole, then they had merely replaced the ghetto of stone with the ghetto of intellect. So in that case, too, most Jews would choose to escape from the prison, and be lost to the Law for ever. All the compromises we have examined collapsed before the majestic logic of this stark choice. "

― Paul Johnson , A History of the Jews
