"My purpose is to have American Jews look away from the success story with which they've cheered themselves up, and to have them remember the classical tradition, whatever it is"

In this quote, Arthur Hertzberg is encouraging American Jews to look beyond the success story they have been telling themselves and to bear in mind their classical custom. He is suggesting that American Jews ought to not be contented in their success, but ought to rather make the effort to reflect on their history and culture. He is emphasizing the value of remembering the classical tradition, whatever it may be, in order to remain linked to their roots and to make sure that their culture and history are not forgotten. Hertzberg is motivating American Jews to take pride in their heritage and to remember the struggles and successes of their forefathers. He is advising them that their classical custom is an important part of their identity and ought to not be forgotten.
