Note, I rushed through this really quick because I needed to have it done, but I’ll have a full version done by the weekend
There are many different formulations of the classic cosmological argument for God’s existence, with the Kalam version being the most popular. Within popular apologetics, many of these other variants are not considered. Thus, this series serves to present and defend several non-Kalam versions of the cosmological argument.
The Argument from Contingency (Simplified Version)
This argument can be traced back to Aristotle, though it was St. Thomas Aquinas who formulated much of the argument in his Summa Theologica. Aquinas reasoned for the existence of a necessary being based on the existence of contingent beings. That is, an infinite being must exist because finite beings exist, otherwise we would end up with an infinite regression. He writes:
The second way is from the nature of the efficient cause. In the world of sense we find there is an order of efficient causes. There is no caseknown (neither is it, indeed, possible) in which a thing is found to be the efficient cause of itself; for so it would be prior to itself, which is impossible. Now in efficient causes it is not possible to go on to infinity, because in all efficient causes following in order, the first is the causeof the intermediate cause, and the intermediate is the cause of the ultimate cause, whether the intermediate cause be several, or only one. Now to take away the cause is to take away the effect. Therefore, if there be no first cause among efficient causes, there will be no ultimate, nor any intermediate cause. But if in efficient causes it is possible to go on to infinity, there will be no first efficient cause, neither will there be an ultimate effect, nor any intermediate efficient causes; all of which is plainly false. Therefore it is necessary to admit a first efficient cause, to which everyone gives the name of God.1
Let us first define a contingent being. Winfried Corduan defines a contingent being as possessing any of the following characteristics:
1. It is restricted by time and space.
2. It can be changed by something other than itself.
3. It has a beginning in time.
4. It needs things other than itself to continue existing.
5. Its attributes, whether essential or accidental, are to some extent influenced by other things.2
Given this information, we can now formulate and demonstrate premise one — that the universe is contingent. Consider a pencil. When I write with the pencil, it undergoes change. It undergoes change because it is made of matter, and a characteristic of matter is that is is mutable. Now since the universe is comprised of matter (which is mutable), then it must be contingent. Says R. C. Sproul:
We know that the chief characteristic of matter is its mutability — it changes, and it changes from one state into another state so that it is nto stable, eternally, and therefore it is in process; it is in a state of becoming and not in a state of pure being. Anything that we find within the universe is changing; it manifests contingency, it is dependent on or derived from something else. These things cannot be the ultimate core of being of the universe.3
Critics usually charge the theist with the fallacy of composition, which is reasoning from a part to the whole. But if matter is mutable and matter makes up the entire universe, then it follows that a universe as a whole is contingent because all of its parts are contingent.
The Nature of Change
Aristotle and Aquinas defined change as moving from potentiality to actuality. That is, change is when the potential of a substance or being is actualized by another being. Consider a window, which has the potential to be broken. This potential is actualized when a force outside of the thing in question acts on it. In the case of the window it’s potentiality is actualized when a boy throws a rock at it or when the wind hurls debris into it. For an object’s potentiality to be actualized, it must already contain some actuality (all potentiality is nothing). The cause must also contain some existing actuality, for potentials cannot actualize themselves (this is analytically false).
Now if all things are contingent beings, then one reaches an infinite regress. For is everything is caused by another infinitely into the past, then ultimately nothing can be caused. How can there be a chain of casualty when there wasn’t a moment where it began. If it can’t even start, then how is it there? Therefore, there must be an beginning to this chain. The beginning is defined as a necessary being, as in that it is pure actuality. It is pure being (otherwise it would be a contingent being if it possessed any potency). Something that is pure actuality is not itself moved, so the “Who made God?” objection is not applicable to this argument (nor for that matter, most other non-Kalam cosmological arguments). It may be objected that the universe or that the laws of nature can be a substitute for this necessary being, but they both fail. The universe has already been shown to be contingent, and the laws of nature are acausal (lacking causal power).
The Argument
Based on what has been demonstrated, an argument can now be formed for God’s existence.
1. The universe is contingent
2. Contingent beings are grounded in a necessary Being (God)
3. Therefore, God exists
