  This remark, “The intelligent will understand,” can be interpreted in various ways. According to some, it indicates that the argumentation presented in the dialogue must have been taken from the Book of Histories, which the narrator also mentioned. Others, however, maintain that it hints at the entire dialogue being a literary fiction. Still, others have suggested that it points to the fact that the dialogue may have been intended for very different kinds of readers and thus written on at least two levels. According to this last interpretation, the Kuzari is addressed on one level to the multitude of Jews in order to reinforce both their traditional opinions and their adherence to the forms of religious observance established by the Talmudic sages.  However, on a second level, it is addressed to those more inclined towards exercising independent judgment in the conduct of life, such as members of the courtier class, philosophers, and their protégés, with a view to providing instruction on how to live responsibly within their own community. These interpretations are by no means exhaustive, but collectively they suggest that Halevi's intentions should not be taken as transparently obvious either in the dialogue as a whole or even in specific exchanges between its interlocutors. Not even the narrator, who comes closest to speaking for Halevi himself, admits to being persuaded by all of the Jewish sage's arguments.  Accordingly, the intelligent reader is expected to follow the arguments and actions of the dialogue with a view to analyzing and identifying the spoken and unspoken assumptions of each speaker, the function of metaphors, analogies, and even oaths, the types and relative cogency of the arguments presented, and the significance of reformulations of earlier statements by the same speaker, if he or she is to understand what is recorded and how it might ultimately change one's life.
