Much as a previous volume published by the Warburg explored the full range of philosophical developments in the 10th century CE, so this collection of 13 papers by leading scholars looks at philosophical literature of the 12th century. Several contributors discuss the most famous thinker of the period, the great commentator Averroes. But the volume casts a wide net, taking in theologians, “philosophical mystics”, and scientists as well as philosophers, and Jewish philosophy as well as Islamic thought. Apart from Averroes, figures emphasized in the volume include al-Ghazali, Ibn Tufayl, ‘Abd al-Latif al-Baghdadi, Abu l-Barakat al-Baghdadi and Suhrawardi.
