What is the correct way to interpret terms when they are used to signify divine attributes? In The Guide of the Perplexed Maimonides addresses this perennial problem. I shall discuss his solution, and on the basis of that discussion I shall attempt to shed light on the question of the relationship between Maimonides' solution and that of St Thomas Aquinas, Maimonides' most illustrious critic. I wish to argue that on this most important of issues the difference between these two universal figures is a good deal less than might readily be supposed. But first it should be said that Maimonides did not make things easy for those of later generations who have sought his help. Part of our difficulty with the Guide is rooted in the pastoral concern which Maimonides had for the strength of faith of those in his care. He recognized that certain of his doctrines lent themselves to misinterpretations which could lead to loss of faith. And we should scarcely expect the greatest leader of twelfth-century Jewry to ignore such a risk. His solution was to write the Guide on two levels, for two classes of people, the philosophically sophisticated and the multitude. Evidently a book which is both esoteric and exoteric leaves room for dispute about the author's intentions. And disputes have duly taken place. But there is a consensus on one critically important matter, namely, the purpose of the Guide. It was written in order to provide a philosophical interpretation of the Bible for conscientiously observant Jews who have at the same time been successful in their philosophical studies. Those studies might set the faith of such Jews at risk, and Maimonides’ intention is to protect their faith. In accepting this as his intention I am taking him at his word.
