When the hub gives way, the wheel flies to pieces

“Remember what Socrates tells Euthyphro, who supposed that the good could be defined by what the gods had willed: if what the gods will is based on some other criterion of goodness, divine will isn’t what makes something good; but if goodness is simply determined by divine will there’s no way for us to assess that judgment.  In other words, if you believe that God ordains morality–constitutes it through his will–you still have to decide where God gets morality from.  If you are inclined to reply, ‘ Well, God is goodness; He invents it,’ you threaten to turn morality into God’s plaything, and you deprive yourself of any capacity to judge that morality.” — James Wood, “Is That All There Is?” (emphasis in original)
