This slim volume translates from the Rabbi Bachye, who wrote one of the first systematic treatments of philosophical Ethics in 12th century Spain. This was during a period of Jewish intellectual cross-fertilization with Islamic culture. Although Bachye was an orthodox Rabbi, he treats Ethics (the Duties of the Heart, in his words) as a universal science, derived from first principles such as the belief in God. This short book also runs very deep.
