To various modern theologians, the Noahide laws represent the inclusive nature of Judaism because they affirm the equality of Jews and non-Jews. To other intellectuals, these seven laws represent natural law which is accessible to all through intellect and does not require revelation. According to Robert Eisen, the second stream of thought ignores how a non-Jew could access these laws without the Jewish revelations. To Eisen, these set of laws impose a Jewish understanding of morality upon non-Jews. To Eisen, the Noahide laws represent more of a barrier between Jews and non-Jews, because non-Jews are forbidden to observe Jewish laws.
