Barry S. Kogan, “Judah Halevi and His Use of Philosophy in the Kuzari,” The Cambridge Companion to Medieval Jewish Philosophy, ed. Daniel H. Frank and Oliver Leaman,  Cambridge University Press, 2003, pp. 111–135.

From the Publisher:

“Influenced originally by Islamic theological speculation, classical philosophers and Christian Scholasticism of the Middle Ages, Jewish thinkers living in Islamic and Christian lands philosophized about Judaism from the ninth to fifteenth centuries. They reflected on the nature of language about God, the creation of the world, the possibility of human freedom and the relationship between divine and human law. This Companion presents major medieval Jewish thinkers in a comprehensive introduction to a vital period of Jewish intellectual history.”
