From the Preface: THE IDEA OF THIS BOOK came to my mind many years ago, after several conversations with my friend and colleague in Jewish educational studies Joseph Lukins professor at the Jewish Theological Seminary in New York. He had suggested that an educated Jew is, among other things, one who lives in some spiritual and cognitive proximity to the weekly Torah reading, the parashat hashavua, "portion of the week." He insisted that issues in the philosophy of education might be in the liturgy's scriptural readings，that even the way messages of tradition divided the Torah into "portions" reflected discrete modes of teaching Torah.In this book, theoretical conceptions, garnered from many places, even if they do not precede reading of Torah, are certainly prisms through whichI can read it.
