Book excerpt: "In this provocative book, Christopher I. Beckwith traces how the recursive argument method was first developed by Buddhist scholars and was spread by them throughout ancient Central Asia. He shows how the method was adopted by Islamic Central Asian natural philosphers - most importantly by Avicenna, one of the most brilliant of all medieval thinkers - and transmitted to the West when Avicenna's works were translated into Latin in Spain in the twelfth century by the Jewish philosopher Ibn Dā'ūd and others. -- Book jacket.
