  For a naturalist like Spinoza, Maimonides is too willing to dismiss science and take refuge in traditional concepts like creation and divine volition. Granted that medieval astronomy did not have a good explanation of planetary motion; with the advent of the scientific revolution, it found one – at least in Spinoza’s opinion. If Maimonides were to remain true to his word and accept the strongest argument wherever it leads, as far as Spinoza’s is concerned, he would have to embrace the new science, the eternity of the world, and the necessity of every event that takes place in it. In order to do this, he would have to abandon the idea that the Bible is a source of philosophic and scientific truth and look to it only for the light it sheds on how to live. Needless to say, this would be a disaster for Maimonides.
