The Amazing Atheist vs. Aquinas: The Third Way

Welcome everyone to Deeper Waters where we are diving into the ocean of truth. We’ve spent a lot of time lately looking at the YouTuber known as “The Amazing Atheist” and his review of the five ways of Thomas Aquinas. Tonight, we’re going to look at the “job” that he did on the third way and see how lacking it is.

First, his summation of the argument.

#1-Contingent things exist.
#2-Each contingent thing has a time at which it fails to exist. Contingent things are not omnipresent.
#3-So if everything were contingent, there would be a time when nothing would exist, call this an empty time.
#4-That empty time would have been in the past.
#5-If the world were empty at one time, it would be empty forever, a conservation principle.
#6-So if everything were contingent, nothing would exist now.
#7-But clearly the world is not empty
#8-So clearly there exists a being who is not contingent.
#9-Hence God exists.

Let’s see what Aquinas himself says:

The third way is taken from possibility and necessity, and runs thus. We find in nature things that are possible to be and not to be, since they are found to be generated, and to corrupt, and consequently, they are possible to be and not to be. But it is impossible for these always to exist, for that which is possible not to be at some time is not. Therefore, if everything is possible not to be, then at one time there could have been nothing in existence. Now if this were true, even now there would be nothing in existence, because that which does not exist only begins to exist by something already existing. Therefore, if at one time nothing was in existence, it would have been impossible for anything to have begun to exist; and thus even now nothing would be in existence — which is absurd. Therefore, not all beings are merely possible, but there must exist something the existence of which is necessary. But every necessary thing either has its necessity caused by another, or not. Now it is impossible to go on to infinity in necessary things which have their necessity caused by another, as has been already proved in regard to efficient causes. Therefore we cannot but postulate the existence of some being having of itself its own necessity, and not receiving it from another, but rather causing in others their necessity. This all men speak of as God.

What Aquinas means by the possibility of to be and not to be is that such objects contain within themselves the potentiality of corruption and can corrupt to the point where they cease to be, that is, cease to be as they are. Keep in mind that for Aquinas, matter only exists when it is combined with form to make substance.

Aquinas says that that which is possible not to be is at some point not. What does he mean? He means that if anything has within it inherently such corruption, it was not at one time as it was depending on another to bring it into being. It is very important to learn what these terms mean and again, I refer the reader to Feser’s guide for an excellent treatment of the five ways.

Aquinas tells us that if all things were like this, there would be a time when there was nothing. Why? Remember Aquinas is open to a universe without a beginning. What he means then is that given infinite time, every potentiality would happen. We cannot speak of an infinite amount of time and that which is possible not happening.

Thus, since everything that is contingent in this way depends on something else bringing it into existence, then there must be something that is not contingent. At this point, the modern atheist can often think “Ah! Well let us suppose the universe is necessary! The third way is refuted!”

Well, no.

Note that Aquinas says that every necessary thing either has its necessity in something else or not. Why? How much sense does this make? What Aquinas means by necessary however is not what modern philosophers mean by talk of possible worlds. What he means is everlasting. As long as something has been, this has been.

Could it be that the universe is the end of the deal then? No. That is because the universe contains matter and matter cannot be the end deal. Matter is pure potential and as was said, it has actuality by being combined with form to make a substance. We could not say the substance is what has always been either because substances are always coming and going out of existence.

Thus, if matter is everlasting, it has to be combined with something else and that combination does not come from itself or it would be the cause of its own coming into existence, which is nonsense.

Now The Amazing Atheist thinks that what Aquinas has forgotten is existence. He tells us about the equipment necessary to make a YouTube video and then says that if you have a hard drive, you can bring back those items that are needed to make a video into existence. Existence itself is the hard drive. It is the universe that is used.

In saying this, he makes the universe the necessary being, which we have said won’t work, but even more embarrassingly, he reveals that he has not read Aquinas at all since he says that Aquinas is unaware of existence as the fallback position. In reality, being, that is, existence as existence, was the central doctrine of Thomistic thought. Only someone completely uneducated on Thomistic thought would make such a basic mistake.

Of course, The Amazing Atheist also gives the same canard of “Well why can’t it be a simple particle? Why must it be a complex God!” This one has been made by Richard Dawkins as well and when someone advances this argument seriously, you can rest assured they have not really read theology and they definitely do not understand Thomistic arguments.

As we said with Dawkins when we reviewed “The God Delusion” and as we said when we reviewed the simplicity of God in the Summa Theologica, if someone will simply read on ahead in the Summa, they will find that this is the very next doctrine God deals with. God is not complex in his being, but rather He is simple. People like The Amazing Atheist and Richard Dawkins and others assume a more materialistic understanding of God which goes against what Aquinas believes. Now you can say Aquinas is wrong in His concept of God, but you must give a reason why his philosophy on this matter is. Aquinas gives arguments for God’s simplicity based on his doctrine of being. Why are they wrong?

Honestly, in listening to this part of the video, I had to laugh when The Amazing Atheist made the statement about existence. Let this be a reminder as we will see later on this week that one really needs to understand the points one criticizes, lest one publicly embarrass themselves.

Tomorrow, we shall examine the fourth way.
