A very rare copy of this classic of Medieval Jewish philosophy, presenting the fears of Spanish Jews, faced with two powerful religions, Christianity and Islam.
Written in 1140 in Arabic, the Kuzari is couched in the form of a dialogue in five books. Charles Touati, in his 1994 preface to the text, summarizes the narrative thread of the work thus: «The king of the Khazars or Kuzari, tormented by the religious question, interrogates – in turn – a philosopher, a Christian theologian and a Muslim one. Disappointed in their answers, he feels he must turn to a learned man of the mocked and vilified minority, a Rabbi, who ends up convincing him, at which the king converts to Judaism and continues his studies with the aid of this teacher.» This apologia allowed Juda Halevi to critique the appeal of philosophy, Christianity and Islam for his contemporaries. According to him, «philosophy denies all possibility of dialogue between Man and God, and does not understand the religious phenomenon» (ibid.). Right from his starting point, a proof of the existence of God, he believes that we need only look to history and the revelation of God on Mount Sinai, witnessed by thousands. Christianity and Islam are for him nothing but forgeries of Judaism: «they jeer at the humiliations and suffering of the Jews without realizing that they exalt, in the founder of their own religions, precisely that humiliation and suffering» (ibid.). The Kuzari is an emblematic text in the sense that it calls for the exiled community to return to Zion rather than submit.
«It is better to leave everything and go back to Zion and there regain Divine favor, instead of wearing ourselves out winning the favor of gentiles which in any case we will never have» (ibid.).
