One of the most popular arguments for the existence of God is known as the Kalam Cosmological Argument. In general, the “cosmological” family of arguments attempt to show that some initial condition necessarily pre-exists the universe, and declare this initial condition (or its cause) to be God. There have been many different versions of the cosmological argument, but the Kalam is particularly popular because it is composed of a very simple syllogism with premises that many people find self-evident. This simplicity makes the KCA very easy for laymen to remember and explain, while professional philosophers love the hidden nuances and depth which underlie the seemingly simple premises. The KCA was first developed and refined by medieval Muslim thinkers like Al-Kindi, Al-Ghazali, and Averroes in the time when the Arab world stood at the pinnacle of Western philosophy and science. Today, arguably the most avid and scholarly proponent of the KCA is Christian apologist, William Lane Craig (whose work has been a frequent focus of this blog), and it will be Dr. Craig’s particular formulation of the KCA which I will be discussing.
The argument is as follows:
- Anything that begins to exist has a cause.
- The universe began to exist.
- Therefore, the universe has a cause.
