In the late Middle Ages, some Jews first banned and then instigated the burning of the books of Maimonides, the greatest philosopher Judaism ever produced. The book burning of 1232 was one episode in a controversy that lasted for some two centuries. The fight was not over Maimonides as an individual, for all agreed he was a great scholar and a pious man, rather the dispute centered on his incorporating Greek learning into his philosophy. Maimonides revered Aristotle; he called him "the philosopher." His opponents attacked him and the intellectual battle raged.
