Logic, Science, and God: The Kalam Cosmological Argument

image

One of my favorite arguments for God’s existence is called the Kalam Cosmological Argument (KCA). It consists of two premises that lead to a logically deductive conclusion. The syllogism goes as follows:

1- Whatever begins to exist has a cause.

2- The universe began to exist.

3- Therefore, the universe had a cause.

Premise One

Let’s begin by analyzing the first premise: “Whatever begins to exist has a cause.” We see examples of this every day in our lives. Through the decay of uranium, lead is caused to come into existence, the car factory causes the car to come into existence, and your parents caused you to come into existence. This premise seems intuitively obvious.

Moreover, a primary metaphysical principle states, “out of nothing, nothing comes.” Consider the fact that if something could come from absolutely nothing, then anything and everything could come from nothing at any time. Moreover, we should be surprised that things don’t come into existence out of nothing all the time. Pizza, music, and Ferraris should just pop into existence out of nothing every day! If something can actually come from literally “no thing,” then why can’t anything or everything come into being from nothing? Why is it just universes? “What is it about nothingness that makes it so prejudiced against everything else but universes?” Obviously, this is a premise that is self-evident.

Premise Two

Since we have established the rationality of the first premise, let’s examine the second: “The universe began to exist.” One common argument against premise 2 is that the universe did not begin to exist but has always been here. Is this logically possible or even scientifically accurate?

Philosophy of Infinity

One philosophical argument promoting this premise involves the logical impossibility of creating an actual infinite number of events in physical space and time to exist. For example, if you start counting 1, 2, 3… you could count forever and never reach a time when you finish counting to infinity. You could count forever, but whatever number you were counting at that exact moment would be an actual finite number. You can always add one more to the number you were currently saying; therefore, you could never reach the end of infinity.

So, is there such a thing as infinity future? Yes, but it will never get here. Is an infinite past possible? If the universe did not begin to exist, then it had to have always been here from past infinity, but then the number of events that happen in the universe would have to be infinite because the universe would be infinite. It would then be impossible to answer many questions…

  1. I’m not as inclined to Classical apologetics (more into the Transcendental Argument) but I got to say the Kalam Cosmological Argument is my favorite of the bunch.
