The present volume contains Maimonides most significant ethical works, newly translated from the original sources by Profs. Raymond I., Weiss and Charles E. Butterworth, well-known Maimonides scholars. Previous translations have often been inadequate - either because they were not based on the best possible texts or from a lack of precision. That deficiency has been remedied in the present text. The translations are based on the latest scholarship and have been made with a view toward maximum accuracy and readability. moreover, the long 'Letter to Joseph' has been translated into English for the first time.
