 The question of peaceful coexistence of different faiths—Christian, Jewish and Muslim—was much discussed in the Middle Ages, especially in the 12th century. Abailard and Raimundus Lullus wrote inter-religious dialogues searching for ways of defending the truth of Christian faith while also seeing some truth—religious or at least ethical—in other religions. In Judaism and Islam, this was mirrored by writers such as Maimonides or Ibn Rushd (Averroes), whose defense of philosophical truth-searching against religious dogma is arguably the most innovative of the period (see esp. Averroes 1180).
