Abstract

In recent years attention has been redirected to the significance of the ethical rule that “good should be done and evil avoided.” It may be called the synderesis rule or principle, since in its most influential presentation it was associated by Thomas Aquinas with the intellectual habit called synderesis. In 1965 Germain Grisez published an article on this subject which attracted much interest in America and England. He argued that the principle as found in Aquinas’s treatise on laws in the Summa of Theology has been misinterpreted in the common Scholastic tradition. In particular Grisez maintained that the common interpretation is wrong in restricting the good and evil, as used in this formula, to the moral order. Further, he suggested that the SR does not have the obligatory force of an imperative.
