Argument From Morality

C.S. Lewis was a modern day proponent of this argument, which essentially points to the existence of universal moral truths that seem to be hardwired into every human being, regardless of race or culture, throughout all of history.

Lewis says in Mere Christianity, “My argument against God was that the universe seemed so cruel and unjust. But how had I gotten this idea of just and unjust? A man does not call a line crooked unless he has some idea of a straight line. What was I comparing this universe with when I called it unjust?”

While there are some differences in what cultures deem right and wrong, every society from the beginning of time has had an innate idea of order and justice.

For example, although societies have differed in their specific rules about murder and sex, every society has created laws to prevent killing at will and engaging in sex with just anyone at any time.

Where did this come from? Was it an evolutionary development, as some scientists today would contend? If so, what makes one person’s morality better than anyone else’s? If morality is not measured against a divine code, how are we to know which set of morals is correct?

This built-in morality serves as another clue to God’s existence.
