Lesson Highlight

The existence of objective moral values and duties.


This is Argument #9 in the 10 arguments we discuss and debate in our ‘Faith, Substance and Evidence’ class. The outline of this argument is presented in the slide below.

Come on to the new Abundant Life Church building at 6:30pm this Wednesday night and we will explore this argument in detail.

C.S. Lewis, in his brilliant book ‘Mere Christianity’, frames this argument for God under the heading “Implied Practice (people are inconsistent moral subjectivists)”. Here’s how he argues for the reality of objective morality:

“1) If ethics (‘the system of application of morals’) is subjective, people view actions they consider “wrong” to only be wrong from their point of view.

2) But without exception, people view wrongs against themselves as actions that are really wrong.

3) Therefore moral values are objective and not subjective.”

Lewis continues: “Whenever you find a man who says he does not believe in a real Right and Wrong, you will find the same man going back on this a moment later. He may break his promise to you, but if you try breaking it to him he will be complaining ‘It’s not fair’ before you can say Jack Robinson. A nation may say treaties do not matter, but then, next minute, they spoil their case by saying that the particular treaty they want to break was an unfair one. But if treaties do not matter, and if there is no such thing as Right and Wrong–in other words, if there is no Law of Nature–what is the difference between a fair treaty and an unfair one? Have they not let the cat out of the bag and shown that, whatever they say, they really know the Law of Nature just like anyone else?”
