Good. Okay, now we have to examine the argument in a little bit more detail. Let’s look at statement one, that everything has a cause. What is our justification for this? This statement is justified by inductive reasoning. All observed things have causes, and so by induction, we extrapolate this to be the general statement that all things have a cause.
The problem is that this extrapolation is done based entirely on the things which are contained inside the universe itself, and so it is unclear how these things can be extrapolated onto things which are not contained within the universe, such as the universe itself. Let me show you why.
When you try to extrapolate this principle to the universe itself, you run into a problem, as you are deriving a principle from the pieces of something (i.e. everything in the universe) and are then extrapolating it to the system as a whole (that is to say, the universe itself). This is the fallacy of composition. Allow me to illustrate the fallacy of composition.
- System A is made out of pieces
- All of the pieces of system A posses property B
- Therefore System A possesses property B
This is what the fallacy of composition looks like, and your argument is an example of it. Allow me to put your argument into this form to demonstrate:
- The Universe is made out of finite things
- All finite things are caused
- Therefore the Universe is caused
It is the fallacy of composition, just like in the previous example. It is fallacious deduce that a system possesses a property simply because every piece of it does.
This is just a general criticism of the form of your argument. We could examine other issues involved as well if you like.
