Abstract
Many of the basic elements of Maimonides' moral psychology are Aristotelian, but there are some important respects in which Maimonides departs from Aristotle. One of those respect concerns the possibility of changing one's character. There is, according to Maimonides, redemptive possibility that Aristotle does not recognize. There is, according to Maimonides, a redemptive possibility that Aristotle does not recognize. This is based on the fact of revealed law. That is, if there is revealed law, then there is guidance for the ordering of one's dispositions to what is good, even though the individual lacks practical wisdom. There is, in the Maimonidean account, both allowance for more plasticity of character, and at the same time a heightened responsibility for acknowledging what is ethically required
