The video above is of Dr. William Lane Craig describing the moral argument for the existence of God. The moral argument is a very powerful argument as nearly everyone can relate with it. At first glance a skeptic would likely be hesitant to agree because of the obvious theistic implications associated with it. However, would an atheist stick to their worldview after seriously pondering the premises of this argument? Let’s take a closer look at what those implications are after reviewing the moral argument itself:
1) If God does not exist, objective moral values and duties do not exist
2) Objective moral values and duties do exist
3) Therefore, God exists
So, the first premise states that if God does not exist, there are not objective moral values. Before we progress, I’d like to define objective as “existing independently of perception or an individual's conceptions”. Now, let’s dissect that premise. For the argument to be valid, God would be the authority on morality if He existed. If He didn’t exist, all observable signs of morality would be pure illusory. That’s to say that these signs of morality would purely be a byproduct of socio-cultural evolution and nothing would be objectively right or wrong. Essentially, by natural selection, our species has developed behavioral patterns that are beneficial to the propagation of our human species.
However, do we witness the lack of objectivity in the moral sense? Do we consider the holocaust in Nazi Germany objectively wrong? How about the raping of a little girl? Or, when the terrorists crashed commercial jets into the Twins Towers on 9/11 and killed thousands of people? If someone were to deny the first premise, that person would then be committed to affirming that these actions are not objectively wrong. These people committing these atrocities are not morally guilty of anything objectively evil under an atheist worldview because there are no objective moral foundations. If God does not exist, these actions would simply be categorized as behaving outside of what would be considered culturally acceptable.
