and received an account of the circumstances of the conversion. In brief it was that the king wishing to know which was the true religion invited representatives of the three dominant creeds, Judaism, Christianity and Mohammedanism, and questioned them concerning the tenets of their respective faiths. Seeing that the Christian as well as the Mohammedan appealed in their arguments to the truth of the Hebrew Bible, the king concluded that Judaism must be the true religion, which he accordingly adopted. This story gave Halevi the background and framework for his composition. He works out his own ideas in the form of a dialogue between the Jewish Rabbi and the king of the Chazars, in which the former explains to the king the essentials of the Jewish religion, and answers the king's questions and criticisms, taking occasion to discuss a variety of topics, religious, philosophical and scientific, all tending to show the truth of Judaism and its superiority to other religions, to philosophy, Kalam, and also to Karaism.

"The world is eternal, and so is the existence of man. The character and ability of a person depend upon the causes antecedent to him. If these are of the right sort, we have a person who has the potentiali-
