C.S. Lewis makes several impassioned pleas for the universality of moral instinct in his writings. I’m most familiar with his appeal to the sense of “fairness” in an argument for God’s existence in Mere Christianity, along with his defence of what he calls the “Tao” in The Abolition of Man. At any rate, in both locations, Lewis is appealing to something like conscience or intuition as the ground of ethics. Ethics are built-in. Right and wrong find their foundation in some innate sense within us. That sense is God’s gift, and is ultimately grounded in God’s own moral character.
Of course, acknowledging the lingering wastes of sin in humanity, Lewis argues that our consciences, as well as our inclination to listen to them, are “bent.” We are not whole and healthy, but twisted and shadowy representations of what we were meant to be.
Working on Bonhoeffer’s moral epistemology, it struck me how different the picture that he describes is. For Bonhoeffer, conscience is only the voice of self-defence. Conscience is the tool by which we usurp God’s judgment, and employ it against ourselves and others. With our consciences–our personal knowledge of good and evil (Genesis 3)–we alternately declare ourselves righteous and then cast ourselves on to the dung pile. Either way, this is an attempt to shield ourselves from God’s voice rather than God’s voice itself. The natural knowledge of good and evil, is nothing less than captivity to death in Bonhoeffer’s estimation. Continue reading “where do we stand? :: Bonhoeffer and Lewis on ethical ground”
