"The Euthyphro dilemma has been addressed by many philosophers and theologians since the time of Plato, though not always with reference to the Platonic dialogue. According to scholar Terence Irwin , the issue and its connection with Plato was revived by Ralph Cudworth and Samuel Clarke in the 17th and 18th centuries. [61] More recently, it has received a great deal of attention from contemporary philosophers working in metaethics and the philosophy of religion . Philosophers and theologians aiming to defend theism against the threat of the dilemma have developed a variety of responses." SEE: http://en.wikipedia.org/wiki/Euthyphro_dilemma
