\"Who Made God?\

If everything needs a cause, doesn't God need one too?

The objection, at its strongest:

1. The argument for God says everything that exists needs a cause.
2. God exists.
3. So God needs a cause, and then that cause needs a cause, forever.
4. Either everything has a cause (so God is not special), or something can be uncaused (so why not the universe?).

In response:

• It misstates the premise. The classical arguments never say everything needs a cause. They say everything that begins to exist, or everything whose existence is dependent/contingent, needs a cause. God is not proposed as one more contingent item, but as the one necessary being whose essence is to exist. Asking "who made the uncaused cause?" is like asking "what is north of the North Pole?"

• This is not special pleading. Special pleading would be exempting God for no reason. But there is a reason: a chain of dependent causes cannot be dependent all the way down, or it never gets started. The regress terminates in something non-dependent by definition: that is the whole point of the argument, not a cheat added at the end.

  St. Thomas makes exactly this move in the Second Way, and gives the uncaused cause its name:

  There is no case known... 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 if it is possible to go on to infinity in efficient causes, 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.

  — Summa Theologiae I, Q. 2, A. 3

• "Why not the universe?" is a fair question with an answer. The universe is the very thing whose contingency we observe: it changes, it is composite, it could have been otherwise. Those are exactly the marks of something that does need explaining, not the marks of a necessary ground.

  It does not help to say the universe is eternal, or self-contained, or that physics finds some uncaused quantum vacuum at the bottom. Those answers confuse duration with necessity. A universe that has always existed has merely been borrowing its existence for a longer time; age does not turn a contingent thing into a necessary one, any more than a debt becomes your own money by being owed for a century. And anything made of parts — fields, particles, space, time — depends on those parts being arranged as they are, and so still asks for a ground beyond itself. Whatever physics names as the deepest layer, if it is composite and could have been otherwise, it is one more thing that needs explaining, not the explanation. A necessary being is not the oldest or smallest item in the universe; it is of an entirely different kind: that whose essence simply is to exist.

This is exactly the reasoning of the Second Way — Causation.
